Product Information

Product Overview

The Manning EC-F2 Sensor is a three-wire, 4/20 mA sensor for Ammonia available in ranges of 0-100 ppm, 0-250 ppm, 0-500 ppm and 0-1,000 ppm.

The Manning EC-F2 exhibits excellent accuracy and precision, with negligible response to common interference gases and dramatic changes in relative humidity. Reliable trip levels as low as 25ppm can be expected with the 0-100ppm sensor. The unit exhibits extremely high reliability with no moving parts.

Monitoring equipment must be configured to indicate a fault if the signal is less than 1.5 mA. All signals over 20 mA must be considered a high gas concentration
