2、 Purpose:
The application of the national standard solution absorption method to collect toxic and harmful gases in the ambient air, and the national standard filter membrane weight method to collect particulate matter in the ambient air, is a new type of comprehensive atmospheric sampler that integrates the collection of harmful gases and particulate matter. It is suitable for unmanned all-weather work and is equipped with a high-strength aluminum alloy PM2.5 multi-stage particulate cutter to collect particles such as TSP, PM10, PM2.5, PM1, etc. It can be widely used in environmental monitoring, health and epidemic prevention, labor protection, scientific research institutions and other departments for sampling harmful gases and particulate matter.
3、 Performance characteristics
1. It has the advantages of small size, light weight, low noise, high degree of intelligence, stable flow rate, and reliable operation. It is equipped with a built-in constant temperature box and illustrated with text, and integrates the collection of harmful gases and particulate matter from the atmosphere.
2. Adopting imported wide temperature OLED display screen, with a good human-machine interface and vivid graphics, easy operation, and user-friendly Chinese graphic display, it can work in ultra-low temperature environments.
3. The microcomputer simultaneously controls three sets of sampling systems for two atmospheric channels and one particulate matter channel, with multiple sampling methods including simultaneous sampling, individual sampling, multiple sampling, alternate day sampling, and cyclic sampling.
4. The dual channel atmospheric and particulate matter three-way sampling systems both use imported DC brushless vacuum pumps and all three channels are electronic flow meters, with high flow accuracy and a fault free usage time of over 20000 hours.
5. The instrument is a dual-purpose AC/DC device with a built-in large capacity imported lithium battery cell. It can work in situations without AC power supply and has a continuous working time of more than 3 hours (when all three channels are fully open and working continuously).
6. Adopting imported pressure and flow sensors, the sampling flow accuracy is high and the stability is good. It can measure atmospheric pressure and temperature, and automatically convert states based on pressure and temperature.
7. Parameters such as sampling flow rate, startup time, sampling time, interval time, and number of cycles can be set.
8. Automatic fault protection function, users can set their own limit protection flow pressure, and if the set flow rate is not reached within the specified time, automatic shutdown protection will be implemented to prevent damage.
9. Built in rechargeable battery for storing data during AC power outages, automatically restoring sampling during AC incoming calls, deducting the power outage time during the sampling process, and allowing users to query the power outage time.
10. The unique three in one design of drying, filtering, and anti backflow suction in the drying cylinder can efficiently dry moisture, filter dust, and reduce the impact of backflow suction on flow rate, achieving long-term operation without cleaning.
11. Users can calibrate various parameters of the instrument through the waterproof keyboard, but they need to enter with a password to ensure the security of the instrument data.
12. Sampling settings and automatic memory settings for sampling data, priority should be given to the next startup, achieving one click sampling.
13. The XA-100 comprehensive atmospheric sampler has a built-in constant temperature box device, which can set the temperature and display the temperature of the absorption bottle. When the ambient temperature is higher than the set temperature, the instrument starts the refrigeration system, and when the ambient temperature is lower than the set temperature, the instrument starts the heating system;
14. Data printing can be done by selecting a micro printer through the RS232 interface, or it can be exported through a USB flash drive.
15. The tripod cloud desktop design is convenient for users to use, and the XA series cutters are made of high-strength aluminum alloy material with anti-static adsorption.
