One of the advantages of the DHI PPC3 we use for our high-end calibration work is that we are able to calibrate all types of barometers. Each sensor in the PPC3 is an absolute pressure sensor of ultra high accuracy so we can test your barometer with ease. We even have pressure ports and chambers for doing the barometers with external air pressure. Please contact us for further information regarding getting your barometer calibrated.
