1、 Model Introduction
The JS-4U cryometer developed and produced by Tianjin Chuangxing is a professional grade gelatin freezing strength measuring instrument. It has a production and sales period of 13 years and is a classic model with a large number of users. The 2022 new JS-4U launched this time is already the Nth upgrade of this model. The upgraded measurement accuracy is 0.01 grams. Real time measurement characteristic curves of freezing force, displacement, and time functions have been added, accurately displaying physical property indicators such as freezing strength, brittleness, viscosity, toughness, creep recovery characteristics, and stress relaxation characteristics of gelatin samples.
