constant flow atmospheric sampler HL-1000
- Product description:
+ Digital display constant current sampler is composed of pump, control circuit, power supply and other parts. Self-contained battery power supply, long power supply time.
+ Can run continuously for more than 20 hours under normal sampling conditions, which is convenient for working sampling.
+ Digital display constant current sampler has additional functions such as power indicator and dust filtering at the inlet.
+ The flow rate can be directly and accurately set through the button without adjusting the knob or valve.
+ The sampling port can be conveniently connected vertically with the sampling tube during sampling, and the operation is simple.
+ Has the advantages of compact structure, small size, light weight, easy to carry, sturdy and durable, strong load capacity, accurate and stable flow display, low noise, etc.
+ Can be carried around when working, and it is a gas constant flow sampling instrument that is more convenient for users to use.
- Product overview:
+ Constant current sampler meets the basic requirements for air samplers such as GB50325-2010, GB/T 17061—1997, HJ/T 400—2007, etc.
+ Building indoor monitoring department, environmental monitoring department,
+ Ideal choice for industrial and mining enterprises and health and epidemic prevention departments to collect various toxic and harmful gases.
+ Can be sampled at the same time with dual flow paths for the determination of formaldehyde, ammonia, TVOC, benzene and other gases in the air.
+ The digital display of sampling flow is more intuitive and accurate.
