Product Introduce: HD***0A is a standalone gas detector alarm, adopting highly accurate gas sensor with excellent sensitivity, stable performance and little drift.With relay output, when the detector senses thecombustible concentration runs up to the preset alarm point( threshold), it will start the acoustic-optical alarm and drive the shut off valve or exhaust fan if any.

Application:HD***0A series Detector is for detecting the combustible gas leakage in in the indoor space where the combustible gas exists, such as house kitchen, hotels, building, etc.
