Description
Features
A wide variety of pressure sensors, oering various
measuring ranges of up to 6,000 bar, are available to
the operator, always ensuring a solution matched to the
application. The individual sensors can be exchanged quickly
and without tools (plug and play) and are automatically
recognised by the digital indicator. Also, as an option, very
accurate temperature measurement with a Pt100 resistance
thermometer is possible. In addition, this instrument
features a large, easily-read display with backlighting (on/o
selectable), a durable housing and simple, clear operation.
Functionality
In addition to mobile and high-precision pressure and
temperature measurement, the CPH6400 also opens up
other helpful applications e.g. recording of pressure and
temperature curves (via the logging function), leak testing
(via the pressure rate function) and peak value determination (via the Min/Max function). These useful functions can
be easily activated or deactivated by pressing the respective
keys.

with optional model CPT6400 reference pressure sensor
Software
Using WIKA's PrintCal software, the logged data, stored in
the CPH6400, can be transferred to a PC via a USB connection, where it can be stored in an EXCEL
®
le for documen-
tation and further evaluation. In addition to this, PrintCal
oers the possibility of PC-supported calibration of pressure
measuring instruments using the CPH6400.
Complete test and service set
For maintenance and service applications, various service
case systems are available. These include pressure service
sets with or without pressure pump, charger, adapter, etc.
Certied accuracy
For each reference pressure transmitter and Pt100 resistance thermometer, the accuracy for the complete measuring
chain is certied by a factory calibration certicate which
accompanies the instrument. Alternatively, on request, a
DKD/DAkkS calibration certicate can be supplied.
