NevadaNano Unveils Next Generation of Flammable Gas Detection

Nov. 2, 2021
Maker of programmable, multi-gas detection technology expands its Molecular Property Spectrometer (MPS) sensors line, adds new miniature-sized model.


RENO, NV, FALL 2021 -- For over four decades, gas leak detection sensor technology has remained relatively unchanged. Today, traditional NDIR and Pellistor gas sensors can be costly and unreliable in most instances. They are prone to conditions that may cause inaccurate readings, false positives, or worse, appear to work when malfunctioning. In addition, they are calibrated to accurately detect only a single gas, so other toxic or flammable gases may go undetected if present.

Realizing the implications of this technology gap, NevadaNano developed unique MEMS technology to create the next generation of flammable gas leak sensors, Molecular Property Spectrometer™ (MPS™) sensors. These sensors are designed to meet the unpredictable environments facing operators in today’s commercial, industrial and institutional building HVAC applications.

Companies who need to monitor atmospheric hazards and the wellbeing of personnel working alone in populated areas, indoors within complex facilities rely on MPS sensors to deliver accurate detection of multiple flammable gases in multi-species environments. They cite these advantages of the MPS sensor technology for operator and site operations:

  • Robust Design: eliminates drift or decay and the need for calibration or maintenance;
  • Multi-species gas: accurately detects multiple gases including hydrogen (H2) in seconds without interference from environmental conditions;
  • Poison Immune: operates reliably even in the presence of environmental contaminants, eliminating sensor failures, false alarms, and misreadings;
  • Fail Safe Design: alerts operators to errors ensuring peace of mind for personnel and assets in hazardous environments.

"MPS technology represents a tremendous leap forward in gas detection sensing," says Bob Christensen, senior director of product development at NevadaNano. "It overcomes the limitations of traditional sensors and delivers more accurate and reliable readings in nearly all environmental conditions. As such, it reduces maintenance costs and costly downtime, and helps create safer environments."


In September at Sensors Converge in San Jose CA, the company launched the “MPS™ Mini”, a miniaturized version of the highly popular MPS. The new sensor is the world’s most accurate hydrocarbon sensor in its class and eliminates the need for maintenance during its 10+year lifetime. 

“We have extended our market-leading reliability, accuracy, and lifetime with enhanced algorithms which extends our market-leading position of detecting 19 of the most common combustible gases found in residential, commercial, and other general use environments,” said Ralph Whitten, NevadaNano's president. “This new product in a lower cost package specifically targets IoT and high volume applications. This enables our customers to set new standards in connected gas sensors and helps companies create safer working environments in industrial, commercial and consumer applications.”

The newest addition to NevadaNano’s MPS product family, the MPS Mini Flammable gas sensor measures the thermodynamic properties of the air-gas mix and accurately reports 0-100% LEL across 19 flammable gases without the need for field calibration. This performance meets the need for flexible sensor platforms in a wide range of non-industrial applications and makes it ideal for residential and commercial applications like smart meters and IoT devices. In essence, the Mini Flammable creates safer environments for people and their surrounding communities.

Integrated, real-time measurements and built-in compensation for temperature, pressure, and humidity enhance the accuracy of all NevadaNano’s MPS flammable gas sensors. Gas concentration readings are accurate across the entire environmental range, including rapid environmental transients, delivering best-in-class accuracy. The Mini Flammable, like all MPS sensors, is inherently immune to drift, decay, or poison.
