Product Description

Product Description

ZH85 Series Household Combustible Gas DetectorsProduct Introduction
The household combustible gas detector continuously monitors the concentration of indoor gas leaks. When the leakconcentration reaches the preset alarm value, it automaticallyactivates audible and visual alarms and can control connected equipment such as solenoid valves or exhaust fans. Thiseffectively helps prevent severe accidents caused by gas leaks,including explosions, fires, poisoning, and asphyxiation.Product Features→MCUmicroprocessor control, offering powerful functionality.
→High-reliability sensor with fast response speed.
→Automatic fault detection and prompt.
→High detection accuracy and resolution.
→Control output modes: one set of passive switch output, one setof DC12V active pulse output.
→Manufactured using SMT process, ensuring strong stability.
→Equipped with wireless remote transmission capability; regularlyuploads device concentration data and real-time status to a remote networked alarm system.
→Automatically places phone calls and sends SMS messages via the supervision platform.
