| EC 23: Reliable and Simple |
GfG's EC 23 transmitter for detecting toxic gases in ambient air is an inexpensive gas detection solution for use in a wide variety of today's industrial applications.. |
Robust housing
The robust aluminum casing protects the transmitter's electronic components from the harshest environments. The corrosion resistant casing protects the electricalcomponents from atmospheric hazards and is dust-tight. |
Simple gas detectionThe EC 23 is the simplest way to monitor ambient conditions. Simply attach the EC 23 to a GfG controller or a PLC to continuously and efficiently monitor the concentration of
hazardous toxic contaminants in air. The EC 23 is also reverse-wire protected to prevent damage due to incorrect wiring of the device. The power connector has a "quick disconnect" feature to simplify transmitter installation and service. |
