WIKA CPH65I0 intrinsically safe pressure calibrator

Click2Contact

The WIKA CPH65I0 is an intrinsically safe pressure calibrator. With an accuracy of 0.025% of span and various additional functions, this instrument is suited to a wide range of applications and, due to its ATEX approval, these also include hazardous areas.

The instrument is available with either one or two built-in reference pressure sensors. This allows 24 different measuring ranges of up to 700 bar to be covered. In addition, the pressure calibrator accepts transmitter output signals (0-24 mA) and the ambient and medium temperature (-40 to +150°C) is measured by a resistance thermometer. A pressure switch test function completes the functionality.

Although it is multifunctional, the robust instrument is simple to operate using three keys. On the 5-digit, backlit display, three measurement parameters can be displayed simultaneously. The battery power supply is designed for at least 35 hours of operation.
