Full Description Specification

Automatic dosing pump and controller for pools, hot tubs and spas

The BL-100 pH controller and dosing pump series is designed to maintain the pH and chlorine balance within hot tubs, swimming pools and spas. This controller achieves this balance by measuring pH, allowing for a rapid increase to keep the balance of your pool, hot tub or spa consistent for comfort, safety and sanitation.

When the pH in a pool or hot tub increases above 7.4, a form of chlorine, known as hypochlorite ion (OCl-) increases. This form of chlorine is 100 times less effective at killing bacteria than the other form of chlorine known as hypochlorous acid (HOCl). As such, it's crucial to maintain the proper pH level to enable effective disinfection with hypochlorous acid, preventing potential sickness and infection while providing a clean, comfortable experience for yourself or your guests.

As an inexpensive non-portable solution for consumers, the BL-100 series offers high-quality, consistent, reliable functionality. Simply insert the probe and injection valve in-line with the recirculation pump and provide the chemical to be dosed, and this innovative instrument does the rest of the work for you. The BL-100-00 is also in-line with HSG282 guidelines for the testing and dosing of water in spa pools and hot tubs, ensuring full compliance with minimal effort.

BL-100-00 features

Peristaltic Dosing Pump

The BL-100 has a powerful built-in peristaltic chemical feed pump that utilizes a stepper motor which does not have any gears or brushes to wear out. This design allows for a long life and little maintenance.

Quick Connect Probe Input

The Quick Connect DIN connector creates a waterproof seal with the controller making it ideal for reducing electrical noise issues with the connection caused by humid environments.

Adjustable Flow Rate

The flow rate from the dosing pumps is adjustable from 0.5 to 3.5L/h. Larger bodies of water require more chemicals to be dosed than smaller ones per unit of time. The adjustable flow rate, like the proportional band, allows for better control in maintaining a desired set point.

Automatic Proportional Pump Control

The peristaltic dosing pump can be controlled by simple on/off or more advanced proportional control, which helps prevent overshooting of the set point. When using proportional control, the programmed flow rate will be impacted by the proportional band used. The closer the reading is to the set point, the longer it takes for the peristaltic pump to complete one revolution. If the reading is outside the proportional band, then the time it takes to complete one revolution is based on the programmed flow rate.

Acid Tank Level/Flow Switch Input

The BL-100 allows for a connection to an optional level controller or flow switch. This input can be used to disable the dosing pump when there is no chemical left in the reservoir tank, or there is no flow due to the pump being turned off.

Programmable Alarm System

Enables or disables the low and high-level alarms for pH. When an alarm is activated, all dosing will stop. For added safety, the alarm system also offers overdosing protection. The meter will go into alarm status if the set point value is not corrected within a programmed time interval.

Multi-coloured LCD Display

The BL-100 features a multi-coloured LCD that provides a quick way to see the status of the pool controller. The display will be green if in control mode and operating as intended. If control is not enabled, the display will be light green. While in an alarm state, the display flashes red.

HSG282-compliant technology

HSG282 guidelines defined by the HSE in 2017 provide clear advice on the practices to prevent infectious pathogens in hot tubs and pool spas. The BL-100 series offers a viable hands-off solution for the twice-daily monitoring of pH levels within hot tubs and spas, plus water dosing to maintain optimal sanitation. Learn more about HSG282 in our complete guide.

The BL-100-00 includes the HI-10053 Amplified pH/Temperature Probe

The BL-100 uses the HI-10053 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, reliable measurements. 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 additional feature is essential since a 0 mV potential will result when the internal glass is cracked and shorts with the reference cell.

For the HI-10053, 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.

BL-100 configurations

  • BL-100-10 pH Controller: The BL-100-10 includes the kit necessary for in-line mounting in addition to the HI-10053 electrode.
  • BL-100-20 pH Controller: The BL100-20 features an on-panel design with a flow cell, plus the HI-10053 electrode.

BL-100-00 pH controller FAQs

Is the BL-100-00 HSG282 compliant?

The BL-100 series includes a highly accurate pH and temperature electrode, the HI-10053, which is entirely in line with compliance requirements for HSG282. For measuring pH, recording and dosing, the BL-100-00 makes your job easier by automating the process and saving time out of your day.

How precise is pH control with the BL-100 series?

The closer the reading is to the set point, the longer it takes for the pump to complete one rotation to improve precision in dosing and pH control. For example, a controller is programmed to have a set point of pH 7.40 with a 1.00 pH unit proportional band and the flow rate at 1.0 L/h. Any reading above pH 8.4 will cause the dosing of acid to be at 1 L/h. If the reading is at pH 7.90, which is 1/2 of the band, the dosing pump will run at half speed or deliver 0.5 L/h of chemical.

Which BL-100 series model is best for my business?

The BL-100 series includes several variations for pH controllers, including an in-line mounting version and an on-panel design. Each model has the same high-quality functionality for high accuracy and fast balancing. Speaking to our knowledgeable pool ambassador directly is the ideal way to decide which solution best suits your requirements.
