Electrochemical Gas Detectors
Durable and High Performance Solutions
It’s a durable and high-performance solution for all gas detection needs in flammable, explosive and toxic environments. Suitable for use in Group II (Zone I and Zone II) and ATEX certified as per international standards.
It’s an intelligent product without need for an additional control system, thanks to its advanced microcontroller, embedded software algorithm, a high quality sensor with a fast response time, and relay outputs that are developed for use in high/low alarm levels.
It provides 4-20mA output support for easy integration to your industrial control and automation systems. Modular wireless communication support is also available which you can easily convert it to an IOT device, whenever you want and you can monitor gas measurement values remotely.
