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.
Structural Features
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.
