Characteristics


1.After long-term natural aging, the internal stress disappears completely without deformation, so the accuracy is high.

2.It is not afraid of acid and lye; it will not rust, no need to be oiled, and it is not easy to stick to dust; it is convenient and simple to maintain and has a long service life.

3.There will be no scratches, and the accuracy of temperature measurement can be maintained at room temperature.

4. It is not magnetized, can move smoothly during measurement, has no sense of stagnation, and is not affected by moisture.
