GQC-2 Explosion proof individual gas samplerDetailed product description：

GQC-2 Explosion proof Individual Gas Sampler is a type of individual sampler specifically developed for long-term low flow sampling in the "Determination of Toxic Substances in Workplace Air" (GBZ/T160). It consists of an air pump, a flow meter, a timing control circuit, a power indicator, and a power supply. This instrument has a compact structure, small size, light weight, easy portability, simple operation, durability, and stable performance, making it an ideal choice for individual sampling in occupational health.

Characteristics of GQC-2/GQC-1 Explosion proof Individual Gas Sampler
1) This product uses a specially designed flow lock card to regulate the flow rate, ensuring that the flow fluctuation during low flow long-term sampling is less than 5%.
2) Choose a more stable suction pump suitable for low flow rates, with a suction negative pressure greater than 5000Pa.
3) 4-digit display timing.
4) Voltage undervoltage indication accompanied by buzzer alarm.
5) GQC-2 type is the same as GQC-1 type and has explosion-proof performance Exia Ⅱ CT4
Attention: 1) It is strictly prohibited to disassemble and charge instruments in explosive gas environments!
2) Battery replacement and maintenance must be provided by our unit to ensure explosion-proof performance.
