Sensorex SD7500CD-ORP Differential ORP Probe, Universal

Overview

Continuous online ORP monitoring in applications like metal finishing and chrome waste treatment wears down ORP sensors, leading to reference contamination. A differential ORP probe utilizes three electrodes instead of two, which extends the sensor’s working lifetime in challenging applications. Replacing the sensor reference ( salt bridge ) and buffered electrolyte solution can prevent sensor replacements, saving time and money. The SD7500CD-ORP is a self-powered differential ORP probe, allowing use with any conventional ORP transmitter. Differential measurement technology with solution ground Buffered electrolyte reference resists fouling Compatible with any conventional pH/ORP transmitter Replaceable double junction salt bridge Refillable reference solution Two Year limited Warranty
