The El home GD-04A4 gas detector is used for continuous monitoring of the presence of explosive gases in the ambient air, as well as for detecting and warning about exceeding the maximum safe concentrations of such gases. The El home GD-04A4 gas detector is intended for installation in enclosed spaces where there is a possibility of gas leakage from the device or the equipment supplied with it. For it to function properly, no other additional equipment is required. It is small, enclosed in a single housing.

It only requires a single 230 V/50 Hz power outlet. It uses a technologically advanced semiconductor sensor and an electronic control system, which allows it to achieve a high detection level. When the factory-set gas concentration <23% LEL' is exceeded, an optical and acoustic alarm is activated. This increases the likelihood of protecting the user from the risk of poisoning or explosion due to leaking gas.

Natural gas is a colorless, odorless gas that is lighter than air. When combined with oxygen in the air, it forms a flammable and explosive mixture. The greatest danger arises when releasing gas from a tank or a leaking gas stove - ignition can occur from devices above, such as a light switch.
