Fluoride Analyzer and Control System

The ECD Fluoride analyzer utilizes a Fluoride ion selective sensor that converts the analog signals from the electrode cartridge into a digital protocol that allows two way communications with the transmitter. The identity of sensor, measurement type and serial number, are stored in the sensor’s memory along with three calibration registers. When connected to an ECD digital analyzer the sensor’s information is uploaded to the analyzer. This configures the display and outputs of the transmitter to the values appropriate to the sensor’s measured parameter.
