Wireless Infrared Gas Detector for Hydrocarbons

LEL Combustible Gas Sensors & Detectors

The Ultra1000 IR-LEL is a low power wireless gas detector to detect and monitor combustible hydrocarbon gases in air. Detection range is 0-100% LEL (Lower Explosive Limit) using miniature non-dispersive infrared sensing technology (NDIR). The Ultra1000 LEL gas detector is powered by internal rechargeable lithium batteries. The unit can also be connected to an external power supply or a solar panel for continuous operation. The interface and the Radio Transceiver are housed in a flameproof instrument enclosure.
