If the accuracy requirements for hygrothermographs are very high, or if you do not have the conditions and capabilities for calibration, you can choose to send the hygrothermograph to a professional calibration institution for calibration. Professional calibration institutions usually have advanced calibration equipment and professional technicians, and can provide accurate and reliable calibration services.
For example, an electronic manufacturing enterprise needs to calibrate the high-precision hygrothermograph used in its workshop. They sent the hygrothermograph to a professional metrology calibration institution. When choosing a calibration institution, pay attention to choosing an institution with qualification certification to ensure the legality and effectiveness of the calibration results. After sending the hygrothermograph to the calibration institution, you need to fill in the relevant calibration application form and explain the usage and calibration requirements of the hygrothermograph. The calibration institution will perform calibration according to the requirements and issue a calibration report.
