The calorimeter must be verified, which is the core premise to ensure accurate detection. As a core instrument for accurately measuring the heat of substances, the calorimeter is widely used in energy, chemical industry, quality inspection and other fields. Its measurement data is directly related to product quality judgment and energy accounting. If the data is inaccurate, it will lead to quality risks and waste of resources, so verification is a rigid requirement.

The core basis for verification: national mandatory specifications. The current calibration of calorimeters strictly follows the "JJG 672-2018 Oxygen Bomb Calorimeter Verification Regulations", which clearly requires the measurement performance, verification items, and operation procedures of the instrument. Only through verification and obtaining a certificate of conformity can the instrument be legally put into use, which is a mandatory requirement to meet the metrology law and related industry standards.

The key scenario of the current verification. First, the newly purchased calorimeter must pass the first verification before it can be used to avoid factory errors affecting subsequent inspections; second, after the instrument has been repaired, relocated or core components replaced, it needs to be re-verified to ensure that the performance is not affected by changes; third, in daily use, regular verification needs to be carried out according to the cycle, and the routine verification period does not exceed 1 year. If it is used frequently or in a harsh environment, the cycle can be shortened and the long-term stability of the instrument can be guaranteed.

The core value of verification. Through verification, the system error of the calorimeter can be corrected in time to ensure that the measurement results are traced back to the national measurement benchmark, which not only guarantees the authority and credibility of the testing data, but also helps enterprises avoid the compliance risk caused by data inaccuracy, and provides reliable technical support for production and testing.

In summary, the calorimeter needs not only verification, but also strict implementation of the verification work according to the specifications. This is a necessary measure to ensure the performance of the instrument and ensure the accuracy of the data, and enterprises must attach great importance to it.
