SIKA manufactures deadweight testers with an accuracy of 0.015 % of reading and are delivered with a SIKA calibration certificate which is traceable to national and international standards. Without additional costs they can be calibrated according to the local gravity instead of the standard gravity of 9.80665 N/kg. Also certification by a national or international accredited laboratory as DAkkS is available to additional costs. We recommend a recalibration every 2 to 3 years depending on the amount of use.
Deadweight testers are the basic primary standard used and its principle is worldwide accepted for the most accurate measurement of pressure. No other piece of equipment for pressure measurement can match the stability, repeatability and accuracy of the deadweight tester. It is ideal for calibrating pressure transducers, pressure gauges, transfer standards, recorders, digital calibrators, etc.and can also be used to measure directly the pressure in systems and processes where precise measurements are important.
