pH/ORP Sensor Electronics & Instruments

pH is a measure of the acidity or alkalinity of a solution, numerically equal to 7 for neutral solutions, increasing with increasing alkalinity and decreasing with increasing acidity. The pH scale commonly in use ranges from 0 to 14. ORP (oxidation reduction potential) is a method of measuring the degree of completion of a chemical reaction by detecting the ratio of ions in the reduced form to those in the oxidized form as a variation in electrical potential measured by an ORP electrode.

Multi Parameter Transmitter Signet 9900

Single channel interface for various parameters including flow

Signet's 9900 multi parameter transmitter provides a single channel interface for parameters including flow, pH/ORP, conductivity/resistivity, salinity, temperature, pressure, level and other sensors that output a 4 to 20 mA signal. The 9900 transmitter (generation II) has the added capability of supporting the batch module for batching control.
