Field-Proven Next-Generation Gas Detection
NevadaNano develops and manufactures MEMS-based gas sensors for demanding commercial and government applications. Our proprietary Molecular Property Spectrometer™ (MPS™) technology represents a fundamental leap forward in gas sensing, delivering unmatched accuracy, stability, and longevity with no need for calibration or maintenance.
Originally developed at the University of Nevada with support from the U.S. Department of Homeland Security, the MPS™ sensor platform is protected by 27 patents across 43 inventions. NevadaNano holds the exclusive license for this groundbreaking chemical analysis technology and continues to lead the industry in IoT-enabled, intrinsically safe gas detection solutions.
The MPS™ Sensor Family
- MPS™ Flammable Gas Sensor (0–100% LEL)
- MPS™ Methane Sensor (50 ppm – 1,000,000 ppm)
- MPS™ Refrigerant Sensor (detects A1, A2L, and A3 classes)
- MPS™ Configurable Sensor (analog output for drop-in replacements)
All models are available in multiple formats and certified to global safety standards. Each sensor is designed to last over 15 years, immune to poisoning or saturation, and requires no field calibration—a revolutionary advantage over traditional sensor technologies.
Real-World Validation: 8 Years and Counting
When it comes to reliability, nothing speaks louder than long-term data. In early 2017, NevadaNano manufactured and calibrated a batch of MPS™ sensors and placed them in a controlled test environment: 50% LEL methane at 20°C and 50% relative humidity. These sensors have now been running continuously for 8 years without a single recalibration. Throughout this time:
- Accuracy has remained within specifications
- No drift or deterioration has been observed
- Sensor performance remains unaffected by exposure to flammable gases
In parallel, NevadaNano has conducted extensive third-party comparisons against traditional catalytic bead and infrared sensors. These tests showed that while conventional sensors experience degradation, poisoning, or require frequent recalibration—MPS™ sensors maintain their precision and stability, even when exposed to challenging gas mixtures including methane, hydrogen, and propane.
