XA-1 Intelligent Constant Current Atmospheric Sampler
1、 Execution standards
JJG956-2000 Atmospheric Sampler
GB50325-2020 "Code for Indoor Environmental Pollution Control of Civil Building Engineering"
HJ/T375-2007 "Technical Requirements and Testing Methods for Environmental Air Samplers"
2、 Purpose:
This instrument is an intelligent instrument developed by our company specifically for GB50325-2010 "Code for Indoor Environmental Pollution Control of Civil Building Engineering". This instrumentAdopting solution absorption method or activated carbon tube, etcMethod: Collect harmful gases such as formaldehyde, ammonia, benzene, TVOC, SO2, NOx, etc. in the environment and indoor environmentCan be used as a smoke sampler. It is environmental monitoring, engineering quality supervision, and hygieneThe ideal choice for epidemic prevention and other departments to collect various toxic and harmful gases. instrumentIt has the advantages of dual constant current sampling function, good stability, and high accuracy. When adding a large load (connected to the adsorption tubeIn the case of an activated carbon sampling tube,Within the specified flow range, the actual sampling flow can still be accurately displayed.
3、 Performance characteristics
1. Controlled by a microcomputer, it is easy to use, reliable in performance, compact in size, and convenient to use. It uses a wide temperature OLED screen to display images and text.
2. Adopting imported DC brushless motor vacuum pump, with high suction negative pressure, stable flow rate, and a fault free operation time of more than 20000 hours.
3. AC/DC dual-use, built-in high-performance lithium battery can be used in the absence of AC power, with a continuous working time of more than 30 hours, and built-in intelligent heater can be used inLow temperature downsampling is automatically heated by an intelligent heater on the sampling bottle.
4. The unique three in one design of drying, filtering, and anti backflow suction drying cylinder can efficiently dry moisture, filter dust, and reduce backflow suctionSmall impact on traffic, achieving long-term operation without cleaning.
5. It has energy-saving automatic protection function and automatic shutdown function after sampling is completed.
6. Equipped with a rechargeable battery, it can store data during AC power outages, automatically restore sampling during AC incoming calls, deduct the power outage time during the sampling process, and allow users to query the power outage time.
7. Tripod cloud desktop design, easy to operate, can be equipped with a micro printer for data printing through RS232 interface, and can also be exported through USB flash drive.
