The Foxcroft FX-421 pH Analyzer’s unique design and microelectronic technology provides savings during
installation, start-up, and operation to a degree unequalled in today’s market. The solid state pH
sensor’s proven performance is unmatched. It is nonglass, rugged and less likely to break compared to
standard glass electrodes. The solid state electrode is faster to respond, allowing tighter control and stability,
requiring less frequent calibration. Overall, it performs better than any other electrode in its class. All
Calibrations are carried out at the measurement site. There is no need to run back and forth between the
sensor and the receiver. The electronics provide a 4- 20mA output signal as well as a high and low relay. All
are sealed in a plastic, weatherproof, corrosion-resistant
