DID YOU KNOW? WIKA’s vehicles in Gauteng and Western Cape are also ISO 17 025 accredited for pressure and temperature. The Eastern Cape vehicle will be upgraded to SANAS status as the need for this type of certification increases in the region.

make use of the best-in-class calibration equipment. Mobile pressure calibration is facilitated by the Mensor CPG 2500 reference standard which has an accuracy of 0.01% of full scale. Pressure generation is handled by the CPP1200-X Hydraulic Comparison Test Pump. Temperature calibration is done using the CTB9100 oil bath or the CTD9100 dry-block calibrator. Temperature measurements are performed using the CTP2000 Standard Thermometer or the CTP5000 Reference Thermometer. Climate control is recorded using the CPU6000-W weather station. All of these items are available for purchase from WIKA. All WIKA metrologists are not only all experienced calibrators, they also have a lot of insight into best-practice methods for instrument installation and are ready to share this experience. •
