1. Oxygen bomb is automatically raised and lowered, oxygenated and deflated automatically.
2. The advanced refrigeration technology ensures that the temperature difference between the barrel inside and outside the instrument meets the national standard requirements.
3. Compressor cooling and heating technology can be used to work continuously for a long time.
4. Stainless steel vacuum inner barrel. Stirring system uses Germany imported motor.
5. Fast test speed, test cycle ≤8min (fast method), ≤15min (GB / T213-2008)
6. Thermal capacity stability Within three months, the thermal capacity change is ≤0.2%, precision is <0.1%, and temperature resolution is 0.0001K.
7. This product has very good performance and reliability even under severe environment.
8, compact structure, beautiful appearance, easy installation and maintenance, low failure rate.
9, small size, a large number of mold manufacturing, high precision.
10. The repeatability and reproducibility of the calorific value test is better than the national standard GB / T213-2008.
