How to calibrate an aquarium thermometer?

<> ornamental shrimp The thermometer in the aquarium is an effective device for us to test the water temperature, so its accuracy is very important, and we must do a good job of calibrating the thermometer before putting the thermometer into the aquarium.

1. There are two accurate temperature points that we can obtain at ordinary times, one is 0 of the ice-water mixture, and the other is 100 of the boiling water. The Celsius itself, which we commonly use, is defined by these two temperatures (in the case of a plateau with a standard atmospheric pressure on the plains, this is not the case with the plateau). If you have a long glass thermometer that is minus 100, you can measure it accurately with these two points.

Ice water mixture: Remember to mix the water with the ice and let it sit for a while to allow the temperature of the water to stabilize.

2. The more accurate thermometering instrument that we can usually come into contact with is the thermometer. This is a medical device, and it is generally strictly checked and will be more accurate. Traditional mercury thermometers have some of their own characteristics that need to be taken into account:

First of all, the measurement range is relatively small, 35 42 (in fact, the lowest point is about 32-33 when shaken, but the minimum scale is only 35), and secondly, it can only heat up.

Traditional mercury thermometers have a capillary tube at the upper end of the vacuole, from which the mercury will disconnect when the temperature drops, and the mercury column will not come down. This is designed to ensure that the thermometer does not change its readings due to low outside temperatures after it is taken out of the body. So after using it, you have to shake it off.

This design also made it difficult for us to calibrate the fish tank thermometer with a thermometer.

3. How to calibrate? Take a basin of water, just the right amount, too little is not suitable, too much is a waste of water. Put a heating rod in and adjust it to 35 or more.

Put in the fish tank thermometer and let the temperature stabilize (i.e., the heating rod starts to stop heating). Then put in the thermometer when the heating rod light is on, and compare the thermometer and the fish tank thermometer after 2 or 3 minutes, and the difference is the error of the fish tank thermometer. If you want to be more punctual, remember to put a small pump in the water to stir the water.

The higher the room temperature, the more accurate this method is.

That one is broken, and it can only be replaced with a new one.

Question 1: How to use a fish tank thermometer There are many kinds of fish tank thermometers:

1. The use of glass tube thermometer and pointer thermometer is not as simple as the beam talk car, only need to place the thermometer in the water and fix the thermometer on the wall of the fish tank with a suction cup;

2. For liquid crystal thermometer, the thermometer can be glued to the corner of the fish tank, and the highest part of the thermometer needs to be kept lower than the water level;

3. The built-in electronic thermometer is used to adsorb the thermometer in the wall of the fish tank with the suction cup configured with the thermometer, and completely sinks into the water.

4. The external + probe thermometer adsorbs the probe inside the fish tank and completely sinks in the water, and the thermometer is placed outside the fish tank or adsorbed on the outer wall of the fish tank.

Regardless of the form of thermometer, it is generally placed away from the heating rod so that the actual temperature in the fish tank can be better understood.

Question 2: How to use the fish tank thermometer Mine is pasted on the upper part, and the temperature display is exactly the same as the pointer thermometer in the middle of the fish tank.

Question 3: How to use the new thermometer "Warm Rubber Meter for Measuring Water Temperature in Fish Tank" The thermometer comes into contact with water.

Wait about 10 minutes.

Then read Question 4: How to use the thermometer that comes with the five-star fish tank The thermometer sensor head can be submerged in water.

Question 5: What kind of thermometer is used in the fish tank Hook aspect, fish fun home.

Question 6: The best fish tank thermometer is the cheapest, the glass one, one or two dollars a piece, better than anything else, such as what electronic stickers, pointers, even if you use it for a period of time at the beginning, the money is quite expensive.

You can buy two glasses at a time, take the median value, the heating rod is not very accurate, the temperature difference of 2-5 degrees has occurred, so you can only trust the glass thermometer, the lower the water temperature is (if the filter pump is always on, there is no such problem).

Haha, this is all an exclusive secret, and I don't tell him about it.

Question 7: What kind of thermometer is better to use to measure the water temperature in the fish tank? Mercury thermometer.

A mercury thermometer is a type of expansion thermometer. Measuring temperature with a mercury thermometer is not only simple and intuitive, but also avoids errors from external remote thermometers.

Question 8: Can the use of the digital thermometer in the fish tank be put in the water Take a look and see that there are many kinds of thermometers in the fish tank.

Question 9: How to put the fish tank thermometer for help The patch, the glass is in the water, and the digital display probe is in the water, and the display screen is outside.

Question 10: How to measure the temperature of the water in the fish tank. A home thermometer can't measure it. You have to use that kind of liquid gauge that is very long.

Summary. 1. For the fish tank with two lamps, a halogen and a superlight are generally used, and the color temperature of the halogen lamp is generally above 10000K, and the superlight is also called the aquatic plant lamp in many places, and the color temperature is about 6000K. Due to its strong penetrating power, the halogen tube can also get enough light from the aquatic plants at the bottom of the fish tank.

Three lamps are generally two superluminous tubes plus one halogen tube. If it's four, it's basically the same half of the preparation situation.

1. For the fish tank with double lamps, a halogen and a superlight are generally used, and the color temperature of the halogen lamp is generally above 10000k, and the frank or superlight is also called the aquatic plant lamp in many places, and the color temperature is about 6000k. Due to its strong penetrating power, the aquatic plants at the bottom of the fish tank can also get enough light. Three lamps are generally two superluminous tubes plus one halogen tube.

If it's four, it's basically the same half of the preparation situation.

2. The ultra-light tube is generally relatively high in brightness, which is suitable for improving the brightness of the whole vertical group of fish and strengthening the photosynthesis of aquatic plants. The color temperature is pure and pure and all over the 6000K. The brightness of the halogen tube is relatively soft and penetrating, and it is very popular in the seawater tank, and the color temperature is generally above 10000K, such as 12000K for Xirui halogen tube and 10000K for Xiwannian halogen tube.

However, if the fish tank only uses halogen tubes, the overall brightness will not be enough, so it is best to use it with ultra-light tubes.

Summary. Hello, generally there are three kinds of thermometers: kerosene thermometer, bimetal thermometer, and digital thermometer.

Hello, generally there are three kinds of thermometers: kerosene thermometer, bimetal thermometer, and digital thermometer.

These have scales on them.

Just follow the scale above.

This kind of is to see where the red line is, what is the temperature<> yes, it is to look at the red line.

28 degrees.

Large Fish Tank|Aquarium|Aqua World |Transparent swimming pool|Acrylic Fish Tank|The aquarium my tank is meters, how many watts is suitable for it, and where is the best place to put it:

If you are raising big fish in a large fish tank, you must fix the heating rod, because the power of large fish is very large, and it is easy to make the heating rod touch the wall of the fish tank and break it, so we recommend that in addition to fixing the heating rod, it is best to choose a metal heating rod in addition to fixing the heating rod.

The heating rod should avoid direct contact with the glass as much as possible and should not be buried in the bottom sand. Because these practices will lead to uneven heating of the fish tank glass, it is easy to break the tank block.

In the aquarium, the heating rod is placed obliquely or flat near the bottom of the cylinder, so that the heat dissipation effect is better, because the water will rise after heating, and the temperature difference between the hot water generated by the lower part of the rod and the upper part of the rod is relatively small, and the heat conduction will be slower, which undoubtedly reduces the heating efficiency, prolongs the heating time, and wastes energy. And the temperature control device is at the upper end of the heating rod, which will cause the heating rod to stop heating early. However, it really doesn't look good in this way, so many people are still willing to use the heating rod vertically.

At this time, it is necessary to cooperate with a thermometer to adjust the water temperature. The thermometer should be placed away from the heating rod to ensure that the water temperature obtained is not from the hot water that has just been heated.

Do not expose the heating rod to the surface of the water except for the power supply.

If two heating rods are installed in the aquarium, try to install them separately on both sides of the tank to facilitate even heating.

For some insensitive fish, it is best to add a sleeve to the heating rod, which can prevent the fish from being burned.

Personally, I think it should be placed next to the pump, so that because the water is circulating, the water inlet can reflect the problem of the whole fish tank, I don't know what you think, I hope it will help you.

Place it at the end away from the heating rod, in the middle of the water, not too low, not too close, just stick to the cylinder wall.

It's okay to be far away from the heating rod and still see the degree
