The series of high precision platinum resistance thermometers consists of three types: YET-620, YET-620L and YET-620X. This series of instruments uses a cyclic measurement technology, so the sampling rate is still 2 times per second under the condition of dual-channel simultaneous measurement and low power consumption. Thanks to the high-precision circuit principle and high-precision reference source inside the instrument, coupled with accurate factory calibration, the resolution of the instrument reaches 0.01°C, and the factory precision reaches ±(0.3%|t|+0.40)°C.

This series of instruments can support two channels to measure temperature at the same time, the temperature difference of the two channels can be displayed in dual channel mode, and the temperature change curve can be displayed in single channel mode. And support the data alarm function, when exceeding or below the set value, the buzzer alarm, so as to detect the abnormality at the first time during quality inspection and adjust in time.

This series of instruments also opens the point calibration function for users, and the accurate calibration of multiple points can greatly improve the measurement accuracy of the whole machine (system composed of host and probe). This series of instruments supports the most commonly used K, T and J thermocouple probes. This compatibility with multiple types of probes expands the application fields of the instrument.
