Total Grow Control pH Probe These industrial combination pH or ORP sensors use the conventional measurement technique, employing a process pH glass electrode (platinum for ORP) which is compared to a reference electrode in KCL solution. Total Grow Control's combination sensors have been completely modernized with several major upgrades. A new, more durable CPVC shell material provides excellent chemical resistance, and temperature compensation (PT1000RTD) is now a standard option. The temperature element is now embedded in the glass electrode for a faster response. One cable now includes both pairs of wires for process and temperature output. The reference chamber now contains a rugged ceramic double junction, replacing the single junction used in the past. This results in an approximate doubling of the sensor’s lifespan. The convertible design of these probes allows them to be used in both flowthrough and submersion applications, minimizing specialized inventory requirements. These models are installed using a standard 3/4” MNPT compression fitting, giving this sensor drop‐in compatibility with any off‐the‐shelf 3/4” tee. With this design, the probe does not screw into the process line, but is simply inserted through the compression fitting. No more twisted cables mean probe cleaning and system calibration has never been easier.
