The invention provides a calibrating device for calibrating a dissolved oxygen tester and a working method thereof. The calibrating device comprises a central control processing system, a first watertank, a second water tank, a third water tank, a fourth water tank, a displacement assembly and a camera shooting mechanism. The first water tank, the second water tank and the third water tank are respectively provided with a constant-temperature water bath assembly, a bubbler and a temperature sensor. A detected meter probe is detachably installed on the displacement assembly. The displacement assembly can drive the detected meter probe to move to the first water tank, the second water tank, the third water tank or the fourth water tank. The camera of the camera shooting mechanism is alignedwith a detected meter. The constant-temperature water bath assembly, the bubbler, the temperature sensor, the displacement assembly and the camera shooting mechanism are all in communication connection with the central control processing system. According to the calibrating device provided by the invention, the requirements of verification regulations are met in terms of hardware; automatic controlling is performed, the camera collects the meter number, and the number is identified automatically, so that the full automation of the verification process is realized; the verification result is inputted automatically and source tracing is performed; and a certificate and an original record are stored and generated automatically.
Description
technical field [0001] The invention relates to the technical field of calibration equipment for experimental instruments, in particular to a verification device for calibrating a dissolved oxygen tester and a working method thereof. Background technique [0002] As an important water quality analysis instrument, the dissolved oxygen meter needs to be calibrated regularly to ensure the accuracy and reliability of its measurement results. For this reason, the JJG291-2018 "Verification Regulations for Dissolved Oxygen Meters" issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China lists the verification standards for dissolved oxygen meters in detail. Guarantee, preparation of anaerobic water, preparation of saturated dissolved oxygen water and measurement of atmospheric pressure values, etc. The final measurement result of the dissolved oxygen concentration is related to the temperature, atmospheric pressure an...
