5. Long standby time, working continuously for more than 10 hours.
6. Supports more than 30 types of Sensors, and can customize gases according to customer needs.
Principle
This product is a diffusion sampling Gas detector. The target gas (formaldehyde) in the environment enters the instrument by natural diffusion and reacts with the built-in Sensor. The Sensor converts the gas concentration signal into an electrical signal, which is processed by the microcontroller and displays the real-time concentration value on the display screen. When the concentration exceeds the preset Alarm threshold, the instrument will trigger a triple alarm of sound, light and vibration.
Applications
Industrial safety, environment monitoring, occupational health, emergency testing, chemical, oil, gas, municipal, laboratory
