pH600 with wand and probe
The pH600 is a microprocessor controlled, loop powered isolated pH
transmitter with all power being supplied from the two wire current
loop connection. Isolation enables the pH probe to be at a potential
relative to ground without affecting the integrity of the pH
measurement. The two wire connection eliminates the requirement of a
separate supply in addition to the loop supply voltage.
- Temperature-compensated pH or ORP measurement.
- Two-wire field mounted transmitter – suitable for multiple-loop installations with a central controller.
- Local display of pH/ORP and temperature – suitable for use as a stand-alone pH monitor.
- Isolated 4-20mA signal.
- Simple pushbutton operation.
- Tough IP65 die-cast Aluminium enclosure.
- Plug and socket connectors for easy installation and maintenance.
- Tool-free operation – no dip-switches or potentiometers.
- Suitable for masthead mounting (as pictured) or wall mounting.
The pH600 two-wire field mounted transmitters, with the appropriate
sensors, are designed to continuously measure the pH or ORP in
industrial processes. The pH600 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 pH600 can also temperature compensate pH
readings using a 100 ohm TC element.

Model 762 Probe Assembly
With the addition of a Model 762 probe assembly and
electrodes, the pH600 becomes a complete pH sensing unit. The most
common usage of the 762 is with a wand, as shown above. Wands are
available in lengths of 40, 70 and 100cm, although other lengths are
available to special order.
