The eTwin is a compact, easy-to-use equipment consisting of two dosing pumps and two parameters controllers
designed to measure pH, Redox and Chlorine plus the temperature. Mainly conceived for pool’s industry, the
dosing pumps are available either in peristaltic and solenoid versions.
On request the device could be equipped with complete calibration kit, including sensors and mounting
accessories.
