Molecular Property Spectrometer (MPS™) Flammable Gas Sensor

A leading gas detection program begins with leading and reliable gas sensor technology.

Proven, reliable sensor technology that can accurately detect and identify over 14 hazardous gases. 

Blackline Safety’ G7 connected combustible gas detectors the use industry leading Molecular Property Spectrometer (MPS™) Flammable Gas Sensor by NevadaNanotech Systems, Inc. This MPS sensor’s innovative technology delivers TrueLELTM, offering the most accurate readings in the market for over 14 of the most common combustible gases and gas mixes — including hydrogen — while eliminating common issues found with traditional sensors.

MPS sensor can be used complex industrial environments such as Oil & Gas, Petrochemical, Industrial Manufacturing, Water and Wastewater, Hazmat and Fire Response.

Key Features

  • Accurate readings without correction factors
  • 5+ year lifetime
  • Poison immune
  • Fail-safe and self-diagnostic
  • No more false alarms

Automated Gas Classification

In addition to the MPS sensor accurately detecting multiple gases at once, it automatically classifies them into one of six gas categories. All data streams directly to the cloud for industry-leading data analytics, providing visibility into your worksite like never before. In contrast, conventional LEL sensors can accurately detect only a single gas that they were calibrated for, delivering inaccurate readings when exposed to other gases.
