The reliable „WATERFRIEND exclusive MRD-2“ measurement and control system for pH and Redox, is now also available with a built-in osf server.

This enables an easy connection to a computer, a computer network and the Internet.

The „WATERFRIEND exclusive MRD-2“ informs the pool owner or pool professional by e-mail in case of any malfunction about the current situation. The dosing „WATERFRIEND exclusive“ metering system incorporates the latest modern control technology and also a host of other technical features. Several microprocessors continually monitor water quality and carry out high-quality digital controls. The built-in RS-485 interface allows connection to the osf bus system. Two powerful metering pumps are driven by variable-speed stepper motors. The flow rate can be maintained in a range from 0 to 10 liters per hour. This intelligent flow speed controller ensures greater versatile possibilities. Thus the WATERFRIEND exclusive MRD-2 can be adapted to different size pools, water temperatures and user profiles of the pool.

Another special feature is the flow gauge housing with its multi-colored RGB LEDs. They show the maintenance interval of the individual electrodes and serve as an indicator during calibration. The large back-lit display is child‘s play to use. With the osf „WATERFRIEND exclusive MRD-2“ metering system, the glass electrodes have a connecting plug with an integrated transmitter and digital data transmission. Its modern technology allows the use of robust coiled cable. A temperature sensor in the flow gauge housing permanently detects the temperature of the water and causes an automatic temperature adjustment of the controls. As a result the water temperature variation is tested by the electronic controls and the temperature is compensated for depending on the hygiene levels. A digital flow meter calculates the amount of current flowing through the flow housing and thus provides the exact dosage for the metering and control system.
