The TS4000H Toxic Gas Detector is now compatible with the HART communication protocol. It offers protection against a wide range of hazardous industrial gases and is able to safeguard against oxygen deficiency. Its design offers features including event logs, a visible LED and an indicator for remaining sensor life. The TS4000H is also available in a Modbus configuration and with three 8-Amp relays. All electronics are contained within an explosion-proof housing so that sensor information can be processed at the sensor site. The interface module's design supports sensor field replacement without special tools or hot work permits. The detector is easy to install and can self calibrate by activating a magnetic switch and applying gas.
