PRODUCT
GAS DETECTOR
DA-30
Home Use
FEATURES
- With a waterproof structure, it can be used in places with a lot of moisture and water.
- In case of gas leakage, when the set alarm concentration is reached, the sensor detects and informs of the gas leakage with an alarm sound.
- It stabilizes the sensor by using the initial delay circuit for the stable movement of the sensing element.
- It is safe against temperature changes or voltage fluctuation at the place of use.
- It minimized power consumption and stabilized the sensor with the switch constant voltage method

DA-50/51
INDUSTRIAL, 1 CHANNEL
FEATURES
- As a separable type, it consists of an explosion-proof detection unit that detects gas leakage and a receiver unit that receives the detected signal and displays the gas concentration.
- As the receiver unit and detection unit are separated, it is easy to check the gas leakage status of gas facilities at remote locations.
- Accurate detection even in case of minor gas leakage.
- Built-in artificial intelligence algorithm to prevent malfunction by noise.
- Industrial single circuit.
