Peristaltic pump eTwin pH-Rx

for chemicalssolenoid-drivenstationary

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. • Over dosing alarm • PP or PVDF Pump head • O-Ring: Viton® • Valves: Ceramic • Supplied with complete installation kit: Suction hose: PVC Cristal®; Discharge hose: Poliethylene • level control, alarm output relay • three relay selectable from the user, set-point (measures + temperature) or timer • antacid plastic box, backlighted graphic display, wall mounting, IP65 protection degree, complete of installation kit (injection valves, foot filters, suction/delivery tubes). • Backlighted graphic display, 5 keys keypad • 3 relays completely selectable: on timer mode (weekly/daily) or as an additional set-point (including the temperature) • 3 programming menus: set-point, calibration, settings • Measurement range: pH 0 ÷ 14; Redox: - 1000 / + 1400 mV; Temperature 0 – 100 °C (PT100) • Inputs: level probes; flow sensor; PT100 probe; proximity switch • Manual dosing (ON-OFF) 0 ÷ 120 pulses/minute • Proportional dosing by self-regulation of the stroke frequency • Hysteresis • Activation delay when switched on • 1 additional relay dedicated to alarm signals • 4-20mA output fully programmable
