Calibration laboratory

Checking the detector includes checking that these devices are capable of achieving the given check value. Detectors are verified as to whether they respond to a leak of 5 g of refrigerant per year. If the detector is working properly, a positive inspection certificate is issued, which is valid for twelve months from the date of the inspection. The leakage control value and the validity period of such a certificate are specified in the Commission Regulation (EC) No. 1516/2007 of December 19, 2007.

In the case of vacuum pumps, it is checked that they are capable of creating a vacuum of 270 Pa or less. The inspection certificates of these devices, unlike the detectors, do not have a validity period. It is, however, recommended to regularly check the vacuum pumps in order to ensure the appropriate operating parameters of the device.

Calibration of scales, manometers and vacuum gauges allows you to check the measurement error of these devices. This process consists in assigning specific reference values and comparing the indications of the calibrated device with a standard of a higher class and greater accuracy. The measurement standards available at PROZON of the Climate Protection Foundation have certificates issued under the EA MLA agreement in the field of calibration. The standards used confirm the consistency of the measurement results with the units of measurement of the International System of Units (SI). As with the inspection of vacuum pumps, the calibration certificate has no validity period. Despite this, it is worth checking these devices at least once a year to eliminate any errors and confirm the complete efficiency of the devices.
