It is a new-type multi-channel sampler aiming at the current problem of waste of time and energy, high sampling cost due to frequent change of absorption bottles at the intervals during the monitoring of ambient air sampling. The equipment has independent sampling mode, cyclic isokinetic sampling mode etc. and extremely reduces the labor intensity, it is suitable for atmospheric routine monitoring and environmental assessment for factories and mines, environmental protection, labor and hygiene, scientific research, meteorology and other relevant departments, and is currently the optimal ambient air sampler at home and abroad.
HJ/T 375-2007 Technical requirement and test procedures for ambient air sampler
JJG 956-2013 Air sampler
HJ2.2-2008 Technology guide of environmental impact assessment atmospheric environment
Accomplishable simultaneous four-channel sampling, single-channel can also be arbitrarily set
Adopt electronic flow meter, flow rate can be tested via microcomputer system to automatically control the flow rate at the set value and automatically compensate flow fluctuation caused by the change of voltage and resistance.
Adopt new-type brushless diaphragm pump, low power-consumption and low noise
Channel A and B are 24-hour constant temperature sampling, one sample each channel
Channel C and channel D are equal interval cyclic isokinetic sampling, two samples each channel, valid sample can be arbitrarily selected, sampling time and sampling interval can be arbitrarily set
Constant temperature sampling: Adopt electronic semiconductor refrigeration, rapid-heating apparatus, adjustable temperature (15~30)℃, high temperature control accuracy
Accomplishable Real-time sampling, timing sampling, interval sampling
Accomplishable automatic fault protection function: If the flow rate does not reach the set value in a certain time, the equipment will stop operating for protection
Accomplishable power-off protection function: If power off during sampling, it can automatically save data and continue to sample after power resume
Automatically accumulate sampling volume, convert it into sampling volume under standard condition in accordance with atmospheric pressure and temperature
Add high-capacity storage chip, channel A and B can each save 999 files, while channel C and D can each save 250 groups
The above parameters are totally up to the requirements of the relevant national standards. If product upgrades, or image does not match with real machine, please refer to the real machine.
