Pressure is one of the most commonly measured quantities in engineering, which is why exact and reliable pressure measurement is especially important. However, the characteristics of the even best sensor or transducer can be altered by a wide variety of factors. This drift cannot be prevented, and it leads to incorrect readings. Calibration allows these deviations to be measured and documented in a certificate. All pressure measuring devices that significantly affect processes or activities should be calibrated before being used. SIKA‘s mobile test and calibration devices are effective aids for performing the necessary test and calibration tasks quickly.
