working principle
The instrument uses β -ray method. β rays is a high speed flow of electrons through the material when it is partly absorbed , causing strength degradation . Under certain conditions, the amount of attenuation size only to absorb the mass of matter , but not with other physical properties of absorbing material ( such as particle dispersion degree , color, luster , shape, etc. ) has nothing to do , they are able to directly measure the mass concentration of atmospheric particulate matter . TH - 2000 - PM atmospheric particulate concentration monitor with low energy C14 beta source in particulate matter sampling through twice before and after clean filter paper and a particulate filter paper, according to the two's beta is absorbed variation for collecting the quality of the particles on the filter paper. Instrument on the whole design is reasonable, beautiful and easy, easy to use, easy to maintain. Product features
1. The instrument adopts continuous sampling and testing with position detection method, fundamentally solves the measurement error brought by the mobile tape.
2. The instrument is equipped with multiple sensors, which can automatically determine the load on the filter paper and automatic shift paper when its load.
3. The flow measurement instrument USES the digital sensor, accurate control flow control part adopts the PID regulator, the outdoor temperature (30 ~ 60 °C accurately control the import of the cutter when the flow stability in 16.67 L/min.
4. According to user requirements by the native query, print and digital communication methods such as historical data for record.
5. With the outdoor temperature and humidity measurement, the use of digital transmission to ensure the reliability of the measurement, calculation and control.
6. With a variety of digital communication and analog signal interface, can adapt to various external connection of equipment.
7. The instrument has the function of remote transmission (optional), at the same time within the remote monitoring instrument parameters.
8. The instrument input using the buttons and touch two ways, at the same time.
9. The instrument can be extended to the TSP, PM10, PM5, PM2.5, PM1 monitoring (cutter has the national authoritative department inspection report).
