Semiconductor H2 gas sensor Introduction

Semiconductor H2 gas sensor is a gas sensor that uses advanced semiconductor gas detection technology to detect the concentration of hydrogen gas in the environment. The semiconductor H2 gas sensor uses solid metal oxide with high sensitivity to hydrogen as gas-sensitive material, which has fast response speed, small volume, light weight and easy installation of the whole equipment. It can be carried on the portable, fixed, pipe type and other appearance of the gas detector. The hydrogen sensor is widely used in household gas alarm, industrial gas leak alarm, and portable gas detector.

Semiconductor H2 gas sensor Parameters

Product type: Hydrogen semiconductor gas sensor

Detection gas: hydrogen

Measuring range: 100-1000PPM

Standard package: Plastic seal

Loop voltage: ≤24V DC

Load resistance: adjustable

Ambient temperature: 20°C and 2°C

Humidity environment: 55% soil 5%RH

Attention:

1. Avoid exposure to volatile silica vapors.

2, avoid sensor exposure to high concentration of corrosive gas.

3, avoid alkali, alkali metal salt, halogen pollution.

4, avoid the sensor contact with water or immersed in water, easy to cause the sensor sensitivity characteristics decline.

5, avoid applying too high voltage, if the voltage applied to the sensor heating is higher than the specified value, even if the sensor has not received physical damage or damage, it will cause damage to the lead/or heater, and cause the sensor sensitive characteristics to decline.

FAQ

What is hydrogen?

Hydrogen is a kind of elemental form of hydrogen, with chemical formula H₂ and molecular weight of 2.01588. At normal temperature and pressure, hydrogen is a colorless, tasteless, highly combustible and insoluble gas in water. Hydrogen has a density of 0.089g/L (101.325kpa,0°C), which is only 1/14 of that of air, making it the least dense gas known in the world.

What is a hydrogen sensor?

Hydrogen sensor is very sensitive to hydrogen at room temperature and has good selectivity, which can be used as a sensor to detect hydrogen concentration in the environment. Due to the safety requirements in production and life, fast, sensitive and accurate hydrogen sensor is very necessary to avoid the possibility of explosion in time.

What are the applications of hydrogen?

1. The use of hydrogen is determined by the nature of hydrogen. For example, hydrogen is the least dense of all gases and can be filled into a sounding balloon.

2. Hydrogen can be inflatable ball or air boat, used as heat conduction material in the dihydrogen internal cold generator, smelting non-ferrous metals and high purity germanium, silicon, synthetic ammonia, hydrochloric acid, petroleum hydrogenation, hardening oil, high efficiency fuel, hydrogen and oxygen flame.

3. Hydrogen is the lightest gas and is most commonly used to fill hydrogen balloons and airships. Hydrogen is an important chemical raw material.
