Product Description

Hazardous chemical detection sensor

Acid sensor

Product Overview

The acid sensor is a hazardous chemical detection sensor for the prevention, monitoring and response of hazardous material warnings. In manufacturing, we found a sensor that uses chemicals to respond faster than conventional products, prevent malfunctions, and react only to hazardous chemicals. Serial (RS-485) communication output is available to enable the network configuration of the controller and sensor, and it is easy to manage and the stability for industrial safety is improved.


  • Sensor reacts only to the harmful chemicals selectively and the leakage amount and harmful materials can be discriminated

  • Carbon reacting materials using direct chemical reacting type sensor is used instead of electric short circuit type sensor

  • Prevent malfunction due to water and humidity

  • Can be installed directly at the leak location

  • Fast reacting speed

  • Reacts to low concentration hazardous substances

  • Integrated monitoring possible

    : Sensor data accumulation function
    : Mobile communication function
    : Detect product status in real time
