ZR-3731 malodorous gas sampler Introduction
The ZR-3731 malodorous gas sampler uses the air bag method to collect the odor pollution emitted by the ambient air and various malodorous sources (including waters) in different forms, and other toxic and harmful gases suitable for air bag collection.
Executive standard
GB/T 14675-93 "Air quality, determination of malodor, three-point comparison of stinky bag method"
HJ/T 905-2017 "Technical Specifications for Environmental Monitoring of Odor Pollution" Features
> Adopt negative pumping passive sampling method, the sample gas directly enters the air bag from the sampling tube to avoid sample contamination;
> Built-in high-performance lithium battery, can be sampled without external power supply, battery life is more than 6 hours;
> Built-in large-flow sampling pump, fast sampling speed and strong ability to overcome load;
> Built-in inert material solenoid valve to realize automatic detection of air circuit tightness, automatic cleaning, and the number of cleaning times can be set;
> With detection air bag pressure, air pressure automatic protection function, exceeding the air bag pressure setting value, automatic stop sampling function
> The gas pipeline is made of inert material PTFE to ensure no adsorption of the sample;
> With speed control function, three-speed control to meet the sampling requirements of different working conditions;
> Applicable to 1L-10L multi-model sampling air bag;
> Gas sampling tube with filtering function for fixed source collection. Technical parameters
