E2630-LEL Combustible Gas Detector

Features

• Stable long-life metal-oxide sensor
• Range 0...100% LEL
• Two SPDT relays
• UART digital interface

Description

Combustible gas detector E2630-LEL is an easy-to-use instrument intended for underground parkings, boiler houses, kitchens, and other confined spaces, where potentially explosive concentration of combustible gases can accumulate.

The instrument utilises a fully calibrated metal-oxide gas sensor with excellent repeatability, stability and long lifetime.

Two relays with switch-over contact may be used for remote signalling or ventilation control. Flashing LED and internal buzzer give visual and sound alarms.
