What Makes the MPS Sensors Different?

The MPS Sensor Family delivers next-generation multi-gas accuracy for safe operation. Disrupting the Industrial Safety, HVAC, Oil and Gas, as well other markets and applications, the MPS offers the first new technology to these industries in over 40 years.

About NevadaNano MPS Gas Sensors

The MPS Gas Sensors automatically and accurately detects and classifies 12 different flammable gases with high accuracy, eliminating the need for expensive manual field calibration processes or re-programming for different gases. In addition, the sensors are inherently immune to drift and poisoning, thus allowing the original factory calibration to provide high accuracy readings for many years and saving the high cost of frequent calibration and/or replacement. As the world’s first smart flammable gas sensors, they provide accurate readings even when exposed to rapid temperature and humidity changes, unlike other sensors that may temporarily shut down when faced with common environmental changes. These new capabilities eliminate false positives, nuisance alarms and false-negatives providing improved ease of use and safety for users. Equipped with built-in environmental monitoring, the advanced algorithms of the MPS enable accurate results in temperatures from -40˚C to 75˚C, relative humidity ranging from 0 to 99%, and atmospheric pressures from 80 to 120 kPa making the MPS sensors ready to plug and play for the most demanding applications.
