Universal dosing station for controlling and maintaining pH (hydrogen ion concentration), Cl (free chlorine), and Rx (oxygen-reduction potential) of swimming pool water.

For pools of volume from 1 to 1000 cubic meters.

Built-in remote access via Bluetooth and Wi-Fi.



High-precision adaptive logic dosing algorithm for any type of chemistry allows achieving the best parameters while maintaining the required concentration of chemicals in the water with maximum precision.

Automatic chlorine cleanup of the amperometric sensor. By applying a voltage to the sensor electrode, the station performs an automatic cleanup of the sensor's metal base from oxidation. This function allows significantly extending the sensor's lifespan and reducing the need for servicing.

Three gas-discharge entrances allow significantly increasing the accuracy of pH, Cl, and Rx measurements and, consequently, subsequent chemical agent dosing control.
Control of the sensor states of pH, Cl, and Rx. The station uses a special algorithm to analyze the sensor readings at the end of each dosing cycle. If no response is received from the sensors, it sends a notification to check the sensor states and calibrate them.

Two membrane dosing pumps with a performance of 10 L/h and one peristaltic pump with a performance of 1.5 L/h can be set up to dosing any type of chemistry for swimming pools. The second dosing pump can be assigned to any type of chemistry for the swimming pool (default: 1 - pH, 2 - Cl, 3 - Floc).

The ability to connect an unlimited number of duplicate dosing pumps up to 2.2 L/h.

Exclusion of simultaneous dosing of agents Cl and pH-, as their mixing leads to the formation of toxic chlorine in gas form.

Built-in overdosing protection - a regulated maximum allowable daily dosage limit for chemical agents is set to ensure the required concentration in the pool water. The daily dose is set for each type of chemistry. When the upper limit is reached, the station stops the dosing process until the current day is finished. In the following days, if no response is received from the sensor, the station switches to uniform daily dosing until the measuring sensor is re-calibrated, thereby excluding the sudden drop in the daily limit.

Chemical level control in the canister. The level sensor prevents water from backflowing in the dosing line, which prevents chlorine crystallization. The pump stops when the chemical level in the canister is monitored (ACON WEB CONTROL and ACON Bluetooth CONTROL are included in the package).


The station has three types of flow control:

  • Connecting to the station via 220 V with a filtering pump;
  • Connecting a filtering control block;
  • Connecting a flow sensor.

Possible measurement and indication of water temperature in the pool with a temperature sensor (available separately). 
Dosing, measurement, and event logs. The station keeps logs of the consumption of chemical agents, pH, Cl, Rx, and temperature, as well as event logs, which records emergency situations and daily reporting on dosing for each type of chemistry.



Matrix display with intuitive interface in both Russian and English. 6 control buttons allow you to easily navigate through the station's menu.

Built-in Wi-Fi and Bluetooth modules. Remote control is carried out through mobile applications ACON WEB CONTROL and ACON Bluetooth CONTROL.

Access to the application is divided into 3 levels:

  • Work. The user section with the ability to monitor values and changes within the range set in the service section.
  • Settings. The service section with the ability to monitor statistics.
  • Service. The service section with the ability to change all the functions of the dosing station via Bluetooth. In the WEB version, some functionalities are not available because certain settings such as sensor calibration or changing the dosing pumps assignment require physical presence at the site.
    By default, the settings and service sections are assigned passwords that can be changed. This level of division allows you to provide access according to the competence of the employee or user.

Email notifications. The station itself forms a message and sends it to the specified email addresses in the settings. This feature allows for immediate reaction to problems in the swimming pool, thereby preventing potentially dangerous situations from becoming critical. In the settings, you can specify up to 3 email addresses to receive emails.

RS-485 interface for connection to "Smart Home" systems.
