Find Gas Detectors by Target Gas

Find products for methane, ammonia, carbon monoxide, carbon dioxide, oxygen and specialty gases by gas name or chemical formula.

Gas packages and sensor options depend on the model. This finder covers the active products technically mapped below; contact NOVEL for the wider portfolio. Acoustic FlexSonic is excluded from this concentration finder because it does not measure gas concentration.

New Cosmos PS-7

New Cosmos PS-7

Uses a sensor cartridge selected for one target gas. Full scale depends on the gas and cartridge; see the product table for 23 gas options.

PERGAM SELMA MPB2 Vehicle Laser Methane Detector

PERGAM SELMA MPB2 Vehicle Laser Methane Detector

SELMA MPB2 is a vehicle-mounted laser methane measurement system designed for bumper installation during mobile gas leak inspections. Utilizing a dedicated suction pump, it draws ambient air samples to measure methane (CH4) concentrations through optical laser absorption. According to manufacturer specifications, the unit delivers a high sensitivity of 0.03 ppm with a rapid measurement cycle of 0.04 seconds. Operating on a 12 V power supply, it is specified for mobile survey operations at vehicle driving speeds of up to 50 km/h.

PERGAM SELMA Duo Methane and Ethane Leak Survey System

PERGAM SELMA Duo Methane and Ethane Leak Survey System

SELMA Duo (Sniffer) is an extractive TDLS analyzer designed for both pedestrian walking surveys and vehicle-based mobile gas leak inspections. It measures methane (0–40,000 ppm) and ethane (0–1,000 ppm) with a 0.01 ppm display resolution. Notably distinct from resolution, the lowest detection limit is <=0.30 ppm for CH4 (<=0.15 ppm with 10-second averaging) and <=15 ppm for ethane (<=10 ppm with 10-second averaging). Field operations are supported via an Android smartphone app, Bluetooth data sync, and GPS route tracking.
