LTH Electronics HPT63
The HPT63 is a microprocessor based pH or Redox transmitter. Two different options of the HPT63 transmitter are available with the Base model offering a single industry standard 4-20mA output. The Advanced HPT63 will offer two 4-20mA outputs enabling the process temperature to be measured and transmitted as well as either the pH or Redox value. The Advanced HPT63 model will have 2 relay outputs for process control and also 3 digital inputs for on-line/off line and clean function selection via a plc.
The HPT63 is able to display the measured value either in pH or Redox (mV) as well as displaying the process temperature in °C or °F. (When using a suitable electrode). The 2 off independent relay outputs can be allocated to either process or temperature measurement, with on/off control, variable hysteresis and time delays along with time and pulse proportional relay operation that is all configurable from the user menu. Relays can also be programmed to energise on a variety of different functions including errors, instrument status, e.g. off-line/calibration mode, or if a dose alarm time has been exceeded.
