Peristaltic pH pump Hanna BL100-00 with pH and Temperature control

The BL100 uses the HI10053 amplified probe that incorporates pH and temperature sensors and connects to the controller with a single waterproof quick-connect DIN connector. The built-in amplifier helps reduce electrical noise from recirculation pumps to provide a stable and reliable measurement. The pH glass used is ideal for low conductivity water and provides a fast response. The PVDF probe body has a 1/2" threaded fitting for insertion into an in-line "T" fitting or flow cell. The probe body has a hex fitting for tightening with a spanner.

As an additional safety feature, the pH sensor is designed to have a value of 0 mV at pH 4 and not at pH 7 as typical pH electrodes do. This is very important as a 0 mV potential will be produced when the internal glass is cracked and shorted to the reference cell. For the HI10053, the 0 mV value will be pH 4 and this type of reading will produce an alarm condition (when programmed) and disable pump dosing. A standard pH electrode would have a pH value close to 7 and could result in no dosing or over dosing depending on the actual value and programmed set point.
