GDR403EAH - AMMONIA Gas Detector (NH3) 0-100 ppm, 4-20mA - With remote Electrochemical cell - Tecnocontrol

The GDR403 detector is ideal for industrial environments requiring reliable monitoring of refrigerant gases.
It features analog outputs (4–20 mA, 1–5 V, 2–10 V), three configurable relays, and Bluetooth for remote diagnostics and maintenance.
Compatible with a wide range of gases, it is equipped with a remote sensor, allowing optimal installation when the detection point is difficult to access.
