IKM Instrutek PC705M Specifications
Digital Pressure Calibrator
PC705M
• Range: 0 to 700 Bar
• Accurate to ± 0,05% FS
• RS485 interface
• EEx/IS approved for
hazardous areas
• Portable - light weight
High accuracy and stability - is achieved by use of a piezoresistive transducer with a built-in temperature
compensation. Unlike some other pressure calibrators, accuracy is maintained when decreasing pressure which
makes the unit ideal for verification of hysteresis. All units are calibrated in positive as well as in negative direction.
Compact and rugged - originally designed for use on offshore drilling rigs, the pressure calibrators offer reliable
performance under the most severe conditions.
Portable - the low weight of only 8 kg makes the units ideal for one-site calibration.
Traceable - each unit is calibrated against precision pressure equipment which is traceable to national standards
and each unit is supplied with a calibration certificate.
Simple and easy - test pressure is established by the integrated hydraulic pump, and the calibration pressure is
read on the graphical LCD display. There is no need for fragile reference gauges.
