YSI ProDSS Digital Water Quality Meter Multiparameter 4 Port Cable 100m Depth
Industrial Gas Alarm Controller for Fixed Gas Detectors and Ventilation Control TH100-4
Product Description
The TH100-4 provides centralized supervision for gas detectors using standard 4 to 20 mA analog transmission.
Measurement information received from connected detectors is displayed locally, allowing operators to check gas concentration, measurement units, alarm conditions and detector faults from one monitoring point.
When gas concentration reaches a configured alarm level, the controller generates sound and light warnings. Relay contacts can simultaneously activate connected safety devices, enabling the gas monitoring system to interact with ventilation fans, solenoid valves and related equipment.
Its wall mounted enclosure is intended for installation in safe locations, while the IP54 protection rating supports reliable operation in typical industrial monitoring environments.
