The Nevada Nano Methane Gas Sensor quickly and accurately measures methane gas at the parts per million molecule (ppm) level.

These methane sensors use a patented Molecular Property Spectrometer technology. MPS™ employs a robust micro-electromechanical system (MEMS) that is inherently poison and drift-resistant. This enables service intervals that can be measured in years.

The sensor's built-in environmental compensation enables reliable, accurate performance across a range of harsh conditions, from -40 to 75ºC and 0-99% relative humidity. This makes the MPS™ Methane Gas Sensor a natural choice for accurate 24/7 methane gas leak detection in harsh, remote, and complex environments both above ground in a grid pattern or in-ground for soil gas analysis.

Sensor Evaluation Kit

The Molecular Property Spectrometer™ Flammable Gas Sensor Evaluation Unit is a user-friendly system developed for assessing flammable gas detection performance. The sensor connects to a provided PCB for communication with a PC (USB) or breakout to individual sensor signals (optional 5-wire harness). A quarter-turn plastic gas mask and housing are included to provide a sealed headspace above the sensor using a tube cap inlet and outlet.

Evaluation Kit part no. MSP999-S40000-99
