Peristaltic pump Hanna BL100-10 with pH and Temperature control (in-line mounting)

Peristaltic pH pump Hanna BL100-10 with pH and Temperature control

The BL100 pH controller and dosing pump is a system designed to maintain the correct pH of pools, hot tubs and spas.

The BL100 is available in three configurations: a meter and electrode option (BL100-00), one that also includes an in-line mounting kit (BL100-10) and a third that includes hydraulic circuitry and a panel-mounted flow cell (BL100-20).

why is it important to maintain a correct pH level in the water?

Chlorine, whether liquid or solid, is alkaline and will raise the pH of the water. As the pH rises above pH 7.4, a form of chlorine known as hypochlorite ion (ClO-) increases. This form of chlorine is 100 times less effective at killing bacteria compared to the other form of chlorine known as hypochlorous acid (HClO). For this reason, it is important to maintain the correct pH level to ensure that the most potent form of hypochlorous acid is available for disinfection. The BL100 has been designed to be an economical solution for the consumer to maintain the ideal pH at all times. Simply insert the probe and injection valve in-line with the recirculation pump to dose the chemical.

HI10053 Amplified pH / Temperature Probe

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 stable and reliable measurement. The pH glass used is ideal for low conductivity water and provides 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 wrench.

As an additional safety feature, the pH sensor is designed to have a value of 0 mV for pH 4 and not at pH 7 like typical pH electrodes. This is very important as a 0 mV potential will occur 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.
