Main technical features

1. ★★Designed a replaceable particle cutter and achievedPM10、PM5、PM2. 5、PM1、TSPMultiple particle separation cutters compatible with total dust.
2. ★Designed an online filter membrane sampler that is compatible with continuous monitoring of dust concentration and filter membrane sampling. It can analyze the composition of collected particles and calculate the mass concentration conversion coefficient of the siteKValue.
3. ★Using a laser light source, the conversion coefficient of mass concentration is not affected by the color of particles.
4. Adopting a large screen LCD display of Chinese characters, Chinese character menu prompts have been implemented.
5. ★Designed a constant current controller, Ensure a constant sampling flow rate and correct cutting curve.
6. Equipped with built-in optical standard scatter board,Ensure high stability of the instrument.
7. ★Featuring a special protective air curtain, it prevents dust from damaging the core components of the instrument—Pollution from optical systems ensures high reliability of instruments .
8. The automatic zero adjustment of the instrument is achieved through computer software, which improves the measurement accuracy of the instrument and facilitates user use.
9. The instrument is designed with a timed sampling mechanism, which can perform timed sampling, start and stop according to the set time. The obtained data can be obtained through Micro printer records or importsPCThe machine processes data to make the instrument suitable for continuous monitoring of inhalable particulate matter in the atmospheric environment.
10. The instrument can set an alarm threshold for dust concentration exceeding the standard. When the dust exceeds the standard, it will automatically sound and light an alarm, or transmit the signal to the control center Conduct monitoring.
11. ★The instrument is designed with an analog output interface, which can draw a purification efficiency evaluation curve when evaluating the air purifier.
12. ★In addition to the general measurement mode suitable for dust monitoring in indoor public places and the timed sampling mode suitable for atmospheric environment monitoring, a new labor hygiene mode has been added. In this mode, according to the hygiene standards of industrial enterprises（GBZ1-2002）Exposure limit standards for harmful factors in the workplace（GBZ2-2007）Calculate the time weighted average（TWA）And the allowable concentration for short-term exposure（STEL）.
