Measuring instruments with microprocessor (1 or 2 channels), pH, Redox (mV), Chlorine (ppm) • Setting the values of 2 SET POINTS for each measurement input • Adjustable hysteresis with respect to the SETPOINT • Relay activation mode ON / OFF or PROPORTIONAL to the measurement value • Relay activation delay time with respect to the SET POINT value
• Minimum and maximum measure alarm • OVER alarm, if the measurement does not reach the SETPOINT value in the selected time • 4 - 20 mA galvanically separated output (one for each measurement channel) • Relay output for alarm status signaling.
