The pH800 is a microprocessor controlled, loop powered isolated pH transmitter with all power being supplied from the two-wire current loop connection.  Isolation enables the probe to be at a potential relative to ground without affecting the integrity of the measurement. The two-wire connection eliminates the requirement of a separate supply in addition to the loop supply voltage.

Features

 

  • Temperature-compensated pH, ISE or ORP measurement.

  • Two-wire field mounted transmitter – suitable for multiple-loop             installations with a central controller.

  • Local display of pH/ORP/ISE and temperature – suitable for use as a stand-alone pH monitor.

  • Isolated 4-20mA signal.

  • Simple pushbutton operation.

  • Tough IP65 die-cast Aluminium enclosure (optional).

  • Push terminals for easy installation and maintenance.

  • Tool-free operation – no dip-switches or potentiometers.

  • Suitable for masthead mounting (as pictured) or wall mounting.

​

The pH800 two-wire field mounted transmitters, with the appropriate sensors, are designed to continuously measure the pH, ORP or electrode potential (mV) in industrial processes.  The pH800 transmitters include all the circuitry necessary for the measurement and transmission of an isolated 4-20mA linear signal. All the transmitter’s functions are accessible through the pushbutton interface – there are no potentiometers or dip-switches.  Two-point calibration of the signal is accomplished using the standard calibration routine.  The pH800 can also temperature compensate pH readings using a 100Ω TC element.
