Based on the previously focused hot runner response speed testing scenario and the relevant background of the full-process calibration of high-precision thermometers, the core tools required for calibration are as follows:
Core reference equipment: A high-precision constant temperature bath, providing a stable constant temperature environment covering the commonly used temperature range of hot runners, paired with a first-class standard platinum resistance thermometer as a traceability reference, achieving an accuracy of ±0.005℃.
Supporting auxiliary tools: A 0℃ freezing point thermostat, providing a stable zero-point reference for calibrating probe zero-point drift; a high-precision multi-channel digital multimeter for accurately acquiring and comparing the difference between two temperature measurement signals.
Environmental assurance tools: A constant temperature test chamber, used to complete environmental stability calibration, simulating performance verification under different temperature ranges and anti-interference conditions.
These tools fully meet industrial-grade metrological calibration requirements, ensuring that the final accuracy of the thermometer is adapted to the hot runner testing needs.
