HI10053 Amplified pH/Temperature Probe The BL100 uses the HI10053 amplified probe that incorporates both pH and temperature sensors and connects to the controller with a single waterproof Quick Connect DIN connector. The built in amplifier helps to reduce electrical noise from recirculation pumps to provide for a stable, reliable measurement. The pH glass used is ideal for low conductivity water and provides for fast response. The PVDF body of the probe has a 1/2” threaded fitting for insertion to an in-line “T” fitting or the flow cell. The probe body has a hex fitting for tightening snuggly with a wrench. As an additional safety feature, the pH sensor is designed to have 0 mV value for pH 4 and not at pH 7 like typical pH electrodes. This is very important since a 0 mV potential will result when the internal glass is cracked and shorts with the reference cell. For the HI10053 the 0 mV value will be pH 4 and this type of reading will produce an alarm state (when programmed) and disable the pump from dosing. A standard pH electrode would have a pH value close to 7 and could result in either no dosing or excessive dosing based on the actual value and programmed set point. 15 Process Instrumentation 15.44 | www.hannainst.com controllers
