Validated 15+ year life, multiple safety certifications, including Intrinsic Safety, robustness, and poison resistance make the Hydrogen Specific MPS™ Sensor the choice for your clean energy transition applications.

The Molecular Property Spectrometer™ (MPS™) Sensor Technology

The heart of the Flammable Gas Sensor is NevadaNano’s proprietary Molecular Property Spectrometer™ (MPS™). NevadaNano originally developed the MPS for demanding military applications and thirty patented inventions and over one hundred trade secrets power the technology. As a truly smart sensor with Built-In-Self-Test, analog or digital outputs and integrated environmental compensation, these sensors perform dozens of measurements to monitor the environment, verify the gas composition and measure the concentration of gas in the air during each measurement cycle to ensure that the reported concentration is more accurate than any other sensor.  In addition, the use of rugged materials and self-cleaning technology ensures that these sensors provide best-in-class performance as the industry’s first sensor not requiring field calibration. Eliminating the requirement for calibration allows customers to use the sensors in demanding, cost sensitive, applications, knowing that expensive calibration or replacement is unnecessary. All of this creates a highly attractive total cost of ownership compared to traditional sensors.
