Sel Watch reagent

The professional choice for control and dosing. The integrated panels based on AP PR Series controllers provide the best authentically ‘plug&play’ solution, preassembled on a panel. There are versions to control pH, ORP and FREE CHLORINE in the water. In addition, they are 100% compatible with saline electrolysis systems.
Our range of controllers provide practically unlimited possibilities, as all our equipment has been designed for integrated work, such as a single communication protocol. This enables the simple integration of third-party devices, as it uses the Modbus protocol, one of the most widely used open network protocols on the market. AP PR-200 equipment is compatible with the Easy Salt, ProChlore Salt, Nature Salt and Neolysis ranges. It is also the recommended professional solution to control several electrolysis systems at the same time with a single regulator-controller panel (multiple control through the TRI kit).

The panels in the CONTROLER range as systems that are fully equipped and assembled. There are therefore ideal for use in water treatment.

Their simple, compact design makes installation and start‑up extremely easy.

They come with all of the components and accessories required for rapid assembly. All assemblies are made of PVC sheets, in various sizes depending on the model.
