When measuring the temperature, aim the temperature measuring instrument at a hot object or person, keep a certain distance, and then press the switch to measure the temperature.

There are options for °C and °F on the thermometer, press this button, you can choose the Celsius and Fahrenheit temperature, and we are more commonly used to use Celsius, that is, °C.

When using an infrared thermometer to measure a person's temperature, you can aim the thermometer at the person's forehead or wrist and press the switch to measure the temperature.

In the process of using the thermometer, it is necessary to pay attention to the use environment, and the use of the thermometer in the environment with smoke and dust will affect the accuracy of the thermometer.

When a thermometer measures temperature, it can only measure the temperature of the surface of the object, not the internal temperature of the object.

Temperature measurement is a quantitative measurement of the temperature of an object with a thermometer. The measurement of the physical quantity of temperature is actually a certain quantity of the object, and the physical quantity should make a monotonous and significant change with the change of the temperature of the object within a certain temperature range. According to the laws of physics, the temperature of the measured object is displayed by the numerical value of the physical quantity.

Pressure thermometry uses pressure as a marker of temperature. There are three types of thermometers in this category: industrial pressure gauge thermometers, constant volume gas thermometers, and vapor pressure thermometers at low temperatures.

The closed system of the pressure gauge thermometer consists of a warm bubble, a connecting capillary tube and a manometer spring, and a certain medium is filled in the closed system. When the warm bubble is heated, the increased pressure is transmitted from the capillary tube to the manometer spring. The elastic deformation of the spring causes the pointer to deflect to indicate temperature.

There are three working mediums in a warm bubble: gas, vapor, and liquid. If the gas medium thermometer uses nitrogen as the medium, it can measure up to 500 550 °C; Using hydrogen as a medium, it can be measured down to -120°C.

Vapor medium thermometers are often used as some low-boiling liquids such as ethyl chloride, methyl chloride, and ether. A portion of the volume of the warm bubble is filled with this liquid, and the rest is filled with their saturated vapors. The liquid medium is usually mercury.

These thermometers are suitable for industrial temperature measurements where measurement accuracy is not required.

The temperature and humidity measuring instrument is a precision measuring instrument that measures instantaneous humidity, temperature and average temperature and humidity by means of a fixed connection to a temperature and humidity probe (humidity module) or a radio temperature and humidity probe (with optional radio module).

The temperature and humidity measuring instrument is composed of three parts: the measurement part, the instrument body, and the PC interface. Apply.

Apply. The temperature and humidity measuring instrument is mainly used in food storage and transportation, museum cultural relics, archives management, building materials experiments, agriculture, forestry and animal husbandry applications, building acceptance, important medical and health places, pipeline maintenance, etc.
