Calibration of anemometers using Rotary Jib Standard (PNE) and Wind Tunnel Standard (TTE) |
price according to agreement |
We carry out calibrations of anemometers using two standards. For lower air flow velocities we use the Rotary Jib Standard constructed by UT Testing Centre and for higher air flow velocities we use the Wind Tunnel Standard that is obtained by the support of EU. We also calibrate thermometers that belong to anemometers. For more information you are welcome to contact Mr. Martin Vilbaste (contact data on our contact page).

| Wind Tunnel Standard (0.5…20) m/s | (0.08…0.6) m/s |
Calibration of air humidity measuring devices |
price according to agreement |
For calibrating air humidity measuring devices we use the secondary humidity standard obtained by the support of EU. The main parts of the standard are the climatic chamber and the chilled mirror dew-point hygrometer. We also calibrate air thermometers that belong to humidity measuring devices. Estonian relative humidity calibration and measurement capabilities (CMC) have been published in the BIPM database.
