Detector Accessories

菱形图标.png Detector Controller

The detector controller is used to supply power and process data for the gas detector. It is based on two-wire and three-wire systems.

Product model: GC-1010-AA/AE, GC-1010-CA, and GC-1020-AA/AE.

Note: The system consists of a detector and a controller. The detector is responsible for sensing toxic and harmful gas in the environment, and sending these signals to the controller or industrial computer in the safety zone through (4~20)mA output.


菱形图标.pngExplosion-proof wiring box

The explosion-proof box is used for all kinds of electrical connection industrial site with explosion proof requirement. The box is also corrosion prevented and easy to use.

菱形图标.pngRC-1000

Our RC-1000 overcomes limitations from traditional potentiometer, magnetic bar and one-way infrared remote control. It can be used to remotely acquire data and set parameters. With the ability to restore setting parameters, one RC-100 can be used for parameter setting and calibration for several detectors.

菱形图标.pngSG-100

SG-100 can be integratively installed on GT detector to give audible alarms and emits red flash light when gas concentration detected exceeds. The locknut design ensures alarm can be observed at any direction. It can be used in combination with all other GT series detectors except two-wire ones.
