1、 Model Introduction
The JS-4Pro freeze strength tester developed and produced by our company is a high-precision, professional grade gelatin freeze strength measuring instrument. The measurement accuracy of freezing strength is 0.001 g, and the deformation displacement accuracy is 0.001 mm, which is the higher accuracy level of current domestic gel measuring instruments. The dynamic mechanical architecture of JS-4Pro; Optimal imported precision motion module configuration with high-precision closed-loop servo motor to ensure displacement accuracy; The high configuration of core components ensures the high-quality comprehensive performance of JS-4Pro. The accuracy, reproducibility, and consistency of measurement results under different detection modes and speeds all prove the value of this instrument: it can provide authoritative, reliable, and verifiable measurement results for professional users.
