Brief introduction

GQC-1Individual gas sampler/GQC-2explosion-proofThe Type I individual gas sampler is specifically designed for the determination of toxic substances in workplace air（GBZ/T160）An individual sampler developed for medium to long term low flow sampling. 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.

twoStructural characteristics

1）This product uses a specially designed flow lock card to regulate flow, ensuring that flow fluctuations during low flow long-term sampling are less than5%.

2）Choose a more stable suction pump suitable for low flow rates, with negative suction pressure>5000Pa.

3）4Digital display timing.

4）Voltage undervoltage indication accompanied by buzzer alarm.

5）GQC-2Same typeGQC-1Type and have explosion-proof performanceExiaⅡCT4

be careful: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.
