NevadaNano’s Molecular Property Spectrometer™ (MPS™) Flammable Gas sensor is powering the next generation of combustible gas detection.

The MPS delivers unprecedented reliability, accuracy, and worker safety by simultaneously detecting over a dozen of the most common combustible gases, including Hydrogen. We call this TrueLEL™. No other sensor can accurately report 0-100% LEL across over a dozen different gases with just one factory calibration, the MPS™ never requires field calibration.

With its robust industrial design, the MPS™ doesn’t drift, decay, or poison and requires no maintenance over its lifetime. And with its data-rich reporting capabilities, the MPS™ will instantly let you know if a fault exists and why. The MPS™ Flammable Gas sensors accuracy is enhanced by integrated, real-time measurements and built-in compensation for temperature, pressure, and humidity. Gas concentration readings are accurate across the full environmental range including rapid environmental transients, delivering best-in-class false positive accuracy.

The MPS™ Flammable Gas sensor is certified intrinsically safe certified, stable, inherently immune to poisons, and never requires servicing or calibration. Sensor readings are output on a UART digital bus providing industry first gas classification or industry-standard analog output for easy integration and improved performance into existing designs.

Legacy flammable gas detection products cannot promise the same combination of accurate and reliable detection of multiple gases across the full environmental range.
