Turbidity Controller TU7685

The Instrument is equipped with two SPDT control relays. Each control relay may be programmed for set-point, high/low, hysteresis or delay time actuation.The unit recognizes automatically standard solutions. The operator may calibrate at any Turbidity value. Analog output Either a 0/20 mA or 4/20 mA programmable and isolated output may be selected, for use as an interface with computers or data loggers. The input range corresponding to the output is programmable. The unit contains a SPST relay designated as an alarm relay. This relay may be used to warn of conditions that may indicate operational problems. The relay will activate on either high/low value conditions, or on failure of the control relays to maintain proper control. In addition, this relay may be activated for dirty probe, lack of water in the cell and external light too high.
