5. Third-party metrology fieldwork: Conduct temperature testing on-site, retain calibration data, and fill out calibration records.

III. Calibratable products

1. Thermocouple

It can calibrate thermocouples of type K, J, E, T, etc., with a measurement range not exceeding 650℃.

2. Thermal resistance

Compatible with PT100, PT1000, and Cu50, suitable for temperature measurement within the range of 35~650℃.

3. Temperature transmitter and display device

4~20mA, 0~10V output temperature transmitter, as well as the supporting digital temperature display and recorder.

4. Plug-in temperature instrument

Bimetallic thermometer, portable temperature probe, surface temperature probe.

IV. Non-verifiable Products and Instructions

1. S-type, R-type, and other high-temperature thermocouples are not applicable.

2. Sensors with temperatures below 30℃ or above 650℃ cannot be calibrated.

3. Non-intrusive devices: Thermal imaging cameras and radiation thermometers. These devices require calibration using a blackbody furnace.

4. Sensors with a protective tube diameter greater than 12mm cannot be placed in the measurement and control system for calibration, and require special customization of the furnace core aperture.

5. Insufficient probe length (such as a short-stem thermistor less than 70mm) results in significant heat dissipation effects and excessive temperature measurement errors.
