Features
A wide variety of reference pressure sensors, offering various measuring ranges of up to 6,000 bar (87,000 psi), 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/off selectable), a durable case 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).

Software
The WIKA-CAL calibration software is available both for the reading of the logger data stored in CPH6400 and for online calibrations in conjunction with a PC. Using this software, the calibration data is automatically transferred into a printable calibration certificate. WIKA-CAL also offers, over and above PC-supported calibration, the management of the calibration and instrument data in an SQL database. Complete test and service set
For maintenance and service applications, various service case systems are available. These include pressure service sets with/without pressure generation, power supply unit/charger, connection adapter, etc. Certified accuracy
For each reference pressure sensor and Pt100 resistance thermometer, the accuracy for the complete measuring chain is certified by a factory calibration certificate which accompanies the instrument. On request, we can provide a DKD/DAkkS calibration certificate for this instrument.
