Introduction
Thank you for choosing our pHix® Compact pH/Redox transmitter. We have done
everything possible to make a pH / Redox transmitter that can fulfill all your demands.
pHix® Compact is very simple to install and connect, as electrode, fitting and transmitter
is built together in the sameNEMA 6X / IP 68 class enclosure. By doing so, all error
sources like e.g. bad cable connections and leaking fittings are eliminated.
As pHix® Compact is equipped with an union flange in one end and male thread in the
other, the transmitter is very easily mounted in open tanks as well as pipes.
You can always contact your representative or the MJK Support for advice and
guidance. Also, take a look at www.mjk.com1
pHix® Compact is registered trademark of MJK.
Measurements and standards used
This manual uses both the US standard measurement system (inches), Fahrenheit and
North American industry standards and the metric measurement system, Celsius and
European industry standards and side by side.
Safety instructions
Read this manual carefully.
Be aware of the environment on the installation site. Wear necessary protective
equipment and follow all current safety regulations.
Always ensure that connected machinery and other equipment are effectively
being put out of service (i.e.by log out/tag out) before commencing setting, fault
finding, service and maintenance work etc.
Repair
Repair must only made by MJK or by a service representative approved by MJK.
Explosion hazardous areas
Note! pHix® Compact must not be installed in explosion hazardous areas!

Construction
pHix® Compact is a loop powered 4-20 mA 4-wire transmitter with power supply and
measuring signal transmitted over the same pair of wires.
pHix® Compact also has Modbus® communication capabilities via the seperate RS485
wires where both the primary measuring signal (pH or redox) and the secondary
measurement signal can be read. Modbus® communication also gives the possibility to
configure nearly all parameters like measuring ranges, electrode parameters and also
buffer settings for buffer adjustment.
Modbus® communication requires that pHix® Compact is connected to a RS485
Communication device or a PLC with RS485 interface. The pH loop must be applied with
10-28VDC supply.
pHix® Compact is delivered as standard for pH or redox (ORP) measurement and
temperature, but can also be delivered with non-standard cable length.
Product identification
Check that the item(s) delivered corresponds to the ordered item(s). The item number is
printed on a label that is sticked onto the packing. Shown in the following, is the label for
a delivery including a pHix® Compact transmitter with pH electrode with zero point at
pH 4,6:

Mounting
Electrode types
The electrode housing is marked with information about electrode type and measuring
range for the actual electrode:
pH electrode, item no. 160310, 1 - 14 pH, 50-176° F /10-80° C, 0 = 4.6 pH.
pH electrode, item no. 160311, 1 - 14 pH, 50-176° F /10-80° C, 0 = 7.0 pH.
Redox electrode, item no. 160312, 176° F /0-80° C.
Mounting the electrode
Upon delivery of pHix® Compact, the electrode is not mounted.pHix® Compact is
configured for the electrode type included in the delivery, and therefore it must only be
used together with the electrode with which it was delivered.
