Description

Applications & Features:
  • PM series transmitters/controllers are designed for monitoring & controlling environment air quality
    ( particulate matter).
  • PMD is suitable for duct 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.
  • Digital technology applied, over voltage and reverse polarity protection, high reliability and anti-interference
    capability.
