PMW : Particulate Matter Transmitter
Applications & Features:
- PM series transmitters/controllers are designed for monitoring & controlling environment air quality
( particulate matter).
- PMW is suitable for wall mount Sensor with good long-term stability, consistency accuracy up to +/-10% readings or +/-10 ug/m3, real-time response and support continuous acquisition.
- MBTF more than 3 years for continuous service (service life up to 8-10 years in typical stable concentration change working conditions and auto(intermittent) work mode), free maintenance.
- All electrical terminals are on the inside bottom, avoid any possible destroy to PCB when wiring Digital technology applied, over voltage and reverse polarity protection, high reliability and anti-interference
- LCD & touch function keys.
- Optional relay output, can set various parameters and functions with LCD and keys, support almost all alarm or
control mode, so the product can be a stand alone controller.
