Product description
Compact and digital measuring and dosing equipment for private swimming pools and spas
The Security Pool Plus combines 2 controllers and 2 dosing pumps in 1 device, controlled by a digital multi-parameter electrode! The Security Pool comes with a complete installation kit, including: combined pH and ORP electrode
with temperature sensor and earth pin, suction and injection lines, tapping saddles (diam. 50 mm), coupling for injectors, calibration fluids, pH and redox, manual.

- 'Intelligent' dosing depending on the correct pH value
Complete kit
The Security Pool comes with a complete installation kit:
- Combined pH and ORP electrode with temperature sensor and earth pin
- Suction and injection lines
- Tapping saddles (diam. 50 mm)
- Coupling for injectors
- Calibration solutions pH and redox
Automatic logging
The values for each parameter are automatically logged every 10 seconds: pH, ORP and °C values, last calibration data, configuration settings and any event data. For review and storage, data can be easily transferred to a PC using a flash drive and the USB port.
Proportional dosage
The BL121-BL122 is equipped with proportionally controlled dosing pumps. Based on the sensitivity of the process to chemical addition, the proportional band can be adjusted. This setting determines the time that the pumps dose as a % of the deviation from the set point. For example, a large amount of water will use a small proportional band. A small band (e.g. 0.1 pH) will cause the pumps to dose more often when the value is close to the set point. For Jacuzzis or spas it is more useful to set a larger proportional band (e.g. 1.0 pH). When the value is close to the set point, the time that the dosing pump operates is minimal, to avoid large fluctuations of pH or ORP. This valuable feature provides very fine control in maintaining the desired set point.
Adjustable flow
The flow rate of the dosing pump is adjustable from 0.5 to 3.5 l/h. Larger pools require more chemicals to be dosed than small ones because it takes more chemicals to see a change in the reading. The adjustable flow rate, like the proportional band, provides better control in maintaining a desired set point.
Programmable alarm
Low and high alarm levels can be enabled or disabled for all parameters. When an alarm is activated, all dosing stops. The system also provides protection against overdose, if the value is not corrected within a specified time interval, the meter will go into alarm status.
Digital outputs
The digital outputs ensure that you can add a number of interesting options to the system: for example, a flow switch to control the circulation of the pump or a level controller to check the liquid level in the chlorine or acid tank.
