1. Gas detection
The combustible gas detector mainly detects combustible gas, and uses methane as the standard to detect the concentration of combustible gas. Depending on the flammable gas in the user's place of use, it can be set according to its main gas as the standard detection gas concentration.
Toxic gas detectors need to know which gas or types of gases to detect. You can choose a single toxic gas detector and alarm instrument, or you can choose a composite toxic gas detector. Yes, or a variety of gases need to be detected.
2. Gas sensor
The combustible gas detector uses a catalytic combustion gas sensor, while the toxic gas detector uses an electrochemical sensor, an infrared sensor or a PID sensor, etc., and the unit concentration of the detected gas is different. Convert.
3. Core components
The alarm of the combustible gas detector adopts a catalytic combustion gas sensor, and the alarm of the toxic gas detector adopts an electrochemical toxic gas alarm method.
If you want to detect toxic gases, you need one-to-one sensors, because different toxic gas sensors are different, such as ammonia, chlorine, hydrogen sulfide, etc., common toxic gases.
If it is to detect flammable gas (flammable and explosive gas), the sensor can be used in general, but the calibration coefficient of each gas is different. Different flammable gases have different chemical properties and different explosion limit values.
The above differences between combustible gas detectors and toxic gas detectors are shared here. The development and application of gas detectors conform to the development of the times and meet the requirements of social production development; with the rapid development of science and technology, high-tech content The gas detector will spring up like mushrooms after a rain.
