RKI S2 MPS type LEL Sensor/Transmitter with XP J-Box 65-2380

Ships in 6 - 8 weeks


RKI S2 MPS (Molecular Property Spectrometer) type LEL Sensor/Transmitter are encased inside a potted package to avoid damage from mechanical abuse or corrosion, and housed in an explosion-proof enclosure.

RKI Molecular Property Spectrometer LEL Sensor internally identifies the gas or gases being detected, and applies the appropriate LEL conversion factor so that it will read a variety of flammable gases or vapors correctly by just utilizing a methane calibration. Capable of detecting over a dozen different combustible gases simultaneously, including Hydrogen, the Molecular Property Spectrometer is unsurpassed in reliability, accuracy, and worker safety. No other sensor can match the accuracy of the MPS in reporting 0-100% LEL across multiple gases. The MPS’s robust design means it won’t drift, decay, or poison over time. Expected sensor life is over 10 years in normal applications.

Key Features:

  • Explosion proof housing
  • Patented water repellent sensor coating
  • Remote mount sensor with calibration adapter
  • 4-20 mA transmitter
  • Operates from 10-30 VDC

Sensor Features:

  • Responds accurately to over 14 gases, with a calibration to methane
  • No conversion factors needed
  • Immune to poisons such as H2S, Silicone, and HCFC’s
  • Requires only annual field response checks
