Product Description
The GD-02A4 gas detector is used for continuous monitoring of the presence of explosive gases in the surrounding air, as well as for detecting and alerting about exceeding the maximum safe concentration of such gases. It is installed in confined spaces where there is a probability of gas leakage from the installation or equipment supplied with it.
It does not require any other additional devices, power cables or batteries for proper operation. It is small in size, enclosed in a single housing. It uses a high-tech semiconductor sensor and electronic control system, allowing it to achieve a high detection rate at a relatively low price of the device. When the factory-set gas concentration <25% of LEL* is exceeded, an optical and acoustic alarm is activated. Such a solution increases the probability of protecting the user from the risk of poisoning or explosion of leaking gas.
Natural gas is a colorless gas with a faint odor and lighter than air. When combined with oxygen in the air, it forms a flammable and explosive mixture. The greatest danger is during a release from a tank or a leak in a gas stove - ignition can occur from appliances above, such as a light switch.
Propane-butane (or LPG) in the gaseous state, unlike natural gas, is heavier than air, so it accumulates first in the lower parts of the premises, the other risks are very similar.
Examples of the lower explosive limits (LEL)* of some gases:
- Gas LEL*
- Methane 5.00%
- Propane 2.10%
- Butane 1.80%
*LEL (Lower Explosive Limit) - the lower explosive limit of gases.
