The JA-60G detects all mixtures of air and combustible gas (Natural Gas, Methane, Propane, Butane, Acetylene, GPL). It has 2 concentration levels with 2 different reactions. The main detector features are: high reliability and sensitivity, compact size, 230V (110V optional) power supply and long stability & lifetime. It has a built-in transmitter to wirelessly send an alarm signal.

Detector specifications
- Sensitivity (concentration):
* Methane: 1st level - 10 ± 3% LEL (0.50% vol) / 2nd level - 18 ± 3% LEL (0.80% vol)
* Propane: 1st level - 18 ± 3% LEL (0.30% vol) / 2nd level - 30 ± 3% LEL (0.50% vol)
* Iso-butane: 1st level - 23 ± 3 % LEL (0.30% vol) / 2nd level - 40 ± 3 % LEL (0.50% vol)
LEL = Lower explosive limit (100%) according to IEC 60079-20-1: for Methane is 4.4% volume concentration for propane 1.7% vol, for iso-butane 1.3% volume, calibrated in the production of iso-butane
