Features:
1. 6 individual controller , one for each unit
2. Each unit provides 5 stations (totally 30 stations), which ensures high test efficiency.
3. With automatic water compensation system
4. Application of double stirring motor reduces temperature fluctuation inside thermal tank and the design of circulation flow road makes the temperature zone more uniform.
5. Easy to observe test condition as the usage of transparent covering lid between test stations.
6. Automatic control of medium temperature and water level, record sample rupture time automatically, all the test records can be printed out.
7. Auto alarm function for temperature or water level abnormal.
