EC 21 0-100 ppm NH3 (NH3) Fixed Transmitter

Features:

• Simple to use and extremely economical
• Robust housing is corrosion resistant and dust-tight
• Linear 4 to 20 mA output signal

The EC 21 is the simplest way to monitor ambient conditions. Simply attach the EC21 to a GfG controller or a PLC to continuously and efficiently monitor the concentration of hazardous toxic contaminants in the air.

The EC 21 is 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.

To determine the mounting position of the EC 21 it is important to know and consider the ambient conditions. To achieve the best results, the ventilation conditions and the density of the gases need to be considered.
