Flyability Elios 3 Flammable Gas Sensor
The Elios 3 Flammable Gas Sensor adds real-time, in-flight detection of 14+ combustible gases — including hydrogen — to your Elios 3. Factory-calibrated with NevadaNano MPS™ technology and built-in self-test, it needs no field calibration and reports gas type and concentration in % LEL directly in the Cockpit app for fail-safe operations in hazardous environments.

Early warning, live in the Cockpit
Get advance notice of explosive atmospheres from hard-to-reach areas. Gas type and concentration in % LEL stream straight to the Cockpit app, with a user-adjustable pre-flight alarm threshold and a built-in MPS self-test.
Real-time LEL detection in flight
The sensor samples the air as the Elios 3 flies, alerting your team to combustible gas the moment it is detected — long before a person needs to enter the space.
NevadaNano MPS™ technology
The Molecular Property Spectrometer is factory-calibrated and self-cleaning, with environmental compensation that eliminates field calibration — so the sensor is always ready when you are.

Detects 14+ combustible gases
From methane and hydrogen to propane, butane, octane and more — the sensor classifies and quantifies a broad range of flammable gases at 0.1% LEL resolution for fail-safe operation.
