HNL's field proven micro-controller based, long-life, accurate, gas-specific transmitters are configured with minimal cross-interference.

It continuously monitors dangerous concentrations of gases. The output transmission can interface directly with any receiving instrument / system.

The standard transmitter consists of a compact electronic module housed in a weather-proof or explosion proof metallic or polyster box, with an application specific sensor. and have :

  • Relay output
  • Explosion proof & IP65, IP55 rating
  • Easy sensor replacement
  • One-man calibration, standard 4-20 mA
  • 2 or 3 wire output, amart sensor interface, HART / MODBUS (RS485).

This state-of-art transmitter is carefully designed and manufacture with industrial grade components for reliability, accuracy and long life. These transmitters are equipped with micro-controller and are optionally featured with self diagnostic, auto-calibration functions through embedded software.
