Description
Sensepoint Toxic NH3 0-50ppm. Sensor M25
The Sensepoint range of flammable, toxic and oxygen gas detectors offer users a high quality, low-cost solution to their industrial gas monitoring needs. Installation in potentially explosive atmospheres is made by the use of a suitable Exd or Exe approved junction box. The industry standard outputs from Sensepoint are connected to either a choice of Honeywell Analytics’ controllers or 3rd party DCS/PLC systems. both flammable and toxic versions are certified to ATEX and IECEx.
