Description

Features

A wide variety of pressure sensors, oering 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.

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

oers 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.

Certied accuracy

For each reference pressure transmitter and Pt100 resist­ance thermometer, the accuracy for the complete measuring

chain is certied by a factory calibration certicate which

accompanies the instrument. Alternatively, on request, a

DKD/DAkkS calibration certicate can be supplied.
