What is the function of a 4 in 1 gas detector?

The four-in-one gas detector can detect oxygen, hydrogen sulfide, carbon monoxide and combustible gas at the same time, of which hydrogen sulfide and carbon monoxide gas can be selected with other gases according to the detection needs of the place.

Applications: agriculture, chemical industry, construction, electric power, fire protection, natural gas, general industry, toxic materials, iron and steel industry, petroleum and petrochemical, sewage treatment.

Applications: combustible gas environment, narrow space, leakage, lack of oxygen, toxic gas environment.

K-600 pump-type four-in-one gas detector is a portable instrument for flexible detection of real-time gas concentration in various scenes, using pump-type detection method, which can quickly and sensitively detect 4 6 gas parameters at the same time.

1) Authoritative explosion-proof certification.

2) High-quality industrial-grade sensor, accurate and durable.

3) Fast and accurate test results.

4) 10 hours long battery life.

5) Waterproof, dustproof and explosion-proof, sturdy and durable.

6) Two-level alarm value setting, frequency conversion reminder.

7) Quadruple alarm of sound and light vibration.

The four-in-one gas detector detects four gases: oxygen O2, hydrogen sulfide H2S, carbon monoxide CO and combustible gas EX.

1. Oxygen O2

o (oxygen molecule, oxygen) is a gas composed of diatomic molecules. It is widely used in nature, chemical production, and medical care. Industrial oxygen is usually produced by separating liquid air, and is usually produced in laboratories by accelerating the decomposition of hydrogen peroxide solutions by manganese dioxide, heating potassium permanganate, or heating compounds of potassium chlorate and manganese dioxide.

2. Hydrogen sulfide H2S

Hydrogen sulfide is an inorganic compound with a chemical formula of H2S and a molecular weight, which is a flammable acid gas under standard conditions, colorless, smelling of rotten eggs at low concentrations and sulfur at very low concentrations.

3. Carbon monoxide CO

A carbon oxide with the chemical formula CO and molecular weight, it is usually a colorless, odorless, and tasteless gas. In terms of physical properties, the melting line point of carbon monoxide is -205, the boiling point is, and it is insoluble in water (20 when the solubility in water is, it is not easy to liquefy and solidify.

4. Combustible gas EX

Combustible gas refers to any gas that can be ignited when exposed to fire, heat or contact with oxidant. The combustion of gases is different from liquids and solids, and does not require processes such as evaporation, melting, etc., which is faster and easier**.

Four-in-one gas detector detection principle and range range:

1. Detection principle.

Depending on the specific gas to be detected, the principle of catalytic combustion and the principle of electrochemistry can be selected.

2. The principle of catalytic combustion.

Combustible gases, methane, hydrogen and other combustible gases.

3. Principles of electrochemistry.

Such as oxygen, carbon monoxide, hydrogen, ammonia, sulfur dioxide, hydrogen sulfide, ozone, etc.

4. Measuring range.

Depending on the specific detection gas, 0-1ppm, 5ppm, 10ppm, 20ppm, 50ppm, 100ppm, 200ppm, 500ppm, 1000ppm, 2000ppm, 5000ppm, 10000ppm, 50000ppm, 10000ppm, 100 lel, 0-2 vol, 5 vol, 10 vol, 30 vol are optional.

5. Resolution.

Or;;; 1ppm (1000ppm and above); Or;;;

6. Support sensors.

Catalytic combustion sensor, electrochemical sensor can be combined in any combination, and can be flexibly configured.

7. Combination.

Single. One, two together.

One, three-in-one. 1. Four-in-one optional (there must be a combustible gas sensor in the four-in-one), and the sensor with more than two-in-one configuration can be independently opened or closed to avoid gas interference and prolong the service life of the sensor.

Hello dear, <>

I am asking a code to answer the main Ze Wu San, I am happy to answer for you: Under normal circumstances, the conventional range of Sihe Chi Stool Changyi gas detector is: 0-1ppm, 5ppm, 10ppm, 20ppm, 50ppm, 100ppm, 200pppm, 500ppm, 1000ppm, 2000ppm, 5000ppm, 1000pp5pm, 100% E, 0-2%, 10%VO, 30%vol optional, 0-30% vol for oxygen, 0-100 ppm for sulfur gas, 0-1000 ppm for -carbon oxide, and 0-100% lel for combustible gas.

Dear, I am very happy to answer for you! The four-in-one gas detector is usually able to monitor and measure a variety of gas parameters at the same time, and the common four-in-one gas detector mainly includes the measurement range of the following parameters:1

LeL Test: Usually expressed as a percentage (%lel) or a lower explosive limit (leL), the measurement range is usually between 0-100% LeL. 2.

Oxygen concentration (O2): Usually expressed as a percentage (%vol), the measurement range is generally between 0-25%vol or 0-30%vol. 3.

Toxic gases (e.g. sulphur dioxide, carbon monoxide, hydrogen sulfide, etc.): The measurement range is usually expressed in parts per million (parts per million) or milligram (milligram per cubic meter), depending on the specific gas being detected. 4.

VOCs (Volatile Organic Compounds): The measurement range is usually expressed in ppm (parts per million) or mg m (milligram per cubic meter), depending on the specific type of VOCs being detected. Hello, the above is mine for your reference.

I hope it will be helpful to you, if you have other questions, you can continue to consult me, I will do my best to answer for you! Have a great day!
