The Molecular Property Spectrometer™ (MPS™) Flammable Gas Sensor is a multi-gas sensing platform that delivers accurate detection and quantification of a wide range of combustible gases using a single factory calibration. Powered by proprietary TrueLEL™ technology, it identifies and measures gas concentrations with high precision, eliminating the need for manual gas selection or field calibration. 

Designed for long-term reliability, the sensor is immune to poisoning and saturation, resistant to drift, and offers a 15-year operational life. Built-in environmental compensation and continuous self-testing ensure stable, fail-safe performance across extreme conditions, from -40°C to 75°C and up to 100% humidity. With ultra-low power options and both digital and analog outputs, the MPS™ sensor enables seamless integration into fixed and portable safety systems while significantly reducing maintenance costs and total cost of ownership.

The MPS™ Pellistor Replacement Sensor is a drop-in replacement for catalytic bead (pellistor) sensors, delivering modern performance without requiring changes to existing device designs. 

Built on NevadaNano’s Molecular Property Spectrometer™ technology, it provides stable, accurate %LEL measurements across methane, hydrogen, and other flammable gases using a single factory calibration. Unlike traditional pellistors, it is inherently resistant to poisoning, immune to saturation, and eliminates issues like masking and drift—removing the need for frequent calibration. 

With a configurable analog output that mirrors legacy sensor signals, it enables seamless integration while significantly improving reliability and safety. The sensor is intrinsically safe, compliant with global performance standards, and offers a 15+ year lifetime, reducing maintenance requirements and total cost of ownership for gas detection systems.

The MPS™ Refrigerant Gas Sensor delivers precise, reliable detection of A1, A2L, and A3 refrigerant gases commonly used in HVAC and refrigeration systems. Built on Molecular Property Spectrometer™ technology, it accurately quantifies refrigerant leaks with high resolution while eliminating false positives through advanced environmental compensation for temperature, humidity, and pressure. Designed for long-term performance, the sensor requires no field calibration, is highly resistant to poisoning and saturation, and offers a 15+ year operational life—dramatically reducing maintenance and total cost of ownership. With a wide operating range (-40°C to 75°C, up to 100% RH), built-in self-test capabilities, and intrinsically safe certifications, the MPS™ Refrigerant Sensor ensures dependable, fail-safe monitoring in demanding environments. Available in multiple configurations with digital and analog outputs, it integrates seamlessly into HVAC, refrigeration, and smart building systems.

The MethaneTrack™ Automated Emissions Monitoring System is a wireless, close-proximity continuous monitoring solution that detects, quantifies, and pinpoints methane emissions in real time. Designed to replace periodic leak surveys, it delivers continuous, automated detection with precise localization and best-in-class quantification—enabling operators to identify and prioritize leaks quickly and reduce LDAR costs.

Intrinsically safe, wireless IIoT sensors can be mounted directly on or near assets, capturing emissions before dispersion for higher accuracy and ultra-low false positives. The system provides real-time alerts, enterprise-wide dashboards, and compliance-ready reporting to support regulatory frameworks such as OGMP 2.0.

With rapid, wireless installation, low maintenance, and automated reporting, MethaneTrack™ improves operational efficiency, reduces emissions, and helps energy operators meet environmental and regulatory goals.
