Gas detector is a kind of special instrument for detecting gas leakage or gas concentration. Gas sensor is the core part of the whole instrument. Gas sensors are good or bad, the most important factor to determine the performance of a device.

The classification of gas detection instrument according to the method of use: Portable / handheld / suction pump / diffusion type, fixed type / online / circulation / wall-mounted.

Advantages and disadvantages of portable and fixed gas detector:

1. Portable gas detector: as a portable instrument convenient operation, small size, with built-in sampling pump, detection quickly, high precision, can be carried to different places, the boot can be used. As a kind of instrument in all kinds of factories and the application of the environmental protection department is more and more widely. But the instrument needs to be charged, not long time detection.

2. Fixed gas detector: can be installed at a specific point of detection for a specific gas leak for 24 hours of continuous detection. This is in the industrial device and the production process using more testing. But the instrument needs to be connected to the power supply to work, not easy to move, and the use of the environment (pressure, temperature and humidity) requires a higher.

Gas detector commonly used detection principle: catalytic combustion, electrochemical, infrared, PID, etc..

Gas detector commonly used concentration units: mg/m3, PPM, Vol%, LEL%, PPHM, ppb, mg/L.

Application of gas detector: furniture, flooring, wallpaper, paint, gardening, interior decoration and renovation, dyes, paper, pharmaceutical, medical, food, fertilizer, antiseptic, resins, adhesives and chemicals, raw materials, sample, process and plant breeding, waste treatment plants, perm places, workshop in biological pharmacy Home Furnishing, environmental protection, animal husbandry, greenhouse cultivation, logistics, fermentation and agricultural production.
