R1234YF Gas Detector GDR453S11
R-1234yf refrigerant Gas Detector, HFO-1234yf Gas Detector 0-1000 PPM 4-20mA Relay, Display & Buzzer - Semiconductor sensor, for non classified area GDR453S11 - Tecnocontrol
GDR453S11 - R1234YF, HFO-1234YF Gas Detector 0-1000 PPM, 4-20mA - With remote Semiconductor sensor - Tecnocontrol
The GDR453 is an industrial gas detector with a remote sensor, designed for installations where it is necessary to separate the sensor unit from the main body.
It supports all standard signals (analog, Modbus, relays) and includes Bluetooth for configuration and diagnostics.
Compatible with refrigerant gases and CO2, it is ideal for complex systems or critical environments.
