In the field of medical devices, the normal operation and accurate diagnosis of many equipment rely on accurate temperature measurement and control. Dry-block calibrators have crucial applications in temperature detection of medical devices. For example, in the calibration of medical thermometers, whether it is a traditional mercury thermometer or an electronic thermometer, dry-block calibrators can provide a stable and accurate temperature standard source to ensure that the measurement error is within an acceptable range, thereby ensuring the accuracy of clinical body temperature measurement. For some high-precision medical imaging equipment, such as the temperature sensor of the superconducting magnet cooling system in magnetic resonance imaging (MRI) equipment, dry-block calibrators can be used for regular calibration to maintain the stable operation of the equipment and ensure the imaging quality. In addition, in some medical devices involving hyperthermia treatment, dry-block calibrators can simulate the temperature environment required for treatment and calibrate and verify the temperature control and monitoring system of the equipment to ensure that patients can obtain a safe and effective treatment temperature during hyperthermia treatment and avoid medical accidents caused by temperature deviation.
