GDR453IC25 - Carbon Dioxide (CO2) Gas Detector 0-5000 PPM, 4-20mA - With remote Infrared 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.
