4Performance characteristics:

1The human-machine interface is friendly, with a large touch screen displaying Chinese characters and Chinese voice. Highly intelligent, the entire experimental process is intelligently controlled by the program, and users only need to input the sample weight and wait for about five minutes to obtain the test data.

2Optimized heating program, adoptingPIDThe mode control of furnace flow not only expands the selection range of resistance values for silicon carbon tubes, but also fully protects them, significantly extending their service life.

3The sample delivery mechanism adopts electronic travel switches, magnetic Hall devices, and non-contact sensing of the sample delivery position.

4The instrument automatically determines the endpoint of the titration test and exits in a timely manner, accompanied by a buzzing prompt, to improve work efficiency.

5Allow users to make overall or segmented corrections for measurement deviations caused by testing conditions, with built-in overall coefficient calculation function, automatically stored after calculation, and simple and easy error correction.
