Built-in intelligent water tank with heating and cooling function, water temperature can keep constant, non-stop working available.

① Stainless steel oxygen bomb, unique stirring method by solenoid pump. Faster heat transfer of oxygen bomb, higher stirring efficiency, test time is greatly reduced.
② High automation: identify oxygen bomb, determination of bucket water volume and control of water temperature and test can be finished automatically.

Reasonable structure, reliable operation, safe and environment friendly

① Reasonable structure, no mechanical failure, stable operation.
② With self-diagnostic function, malfunction can be detected accurately, easy to maintain.
③ Build-in power inverter. System will not be affected by fluctuation of voltage and frequency.

Good environment adaptability, precise, accurate and reliable test result

① Helix tube multi-point isothermal technology, create a controllable and stable internal environment (consists of jacket and jacket lid, temperature difference <0.1℃), stop the interference of external environment ( such as air flow, temperature) to bucket, test result is reliable.
② Independent jacket and bucket water system. After the test, bucket water automatically flow back into water tank, no affection between inlet and outlet of bucket water and jacket water. Jacket water temperature is stabilized.
③ Result of first test is reliable and valid, continuous working time can be 72 hours.

Intelligent control, easy operation

① With Ethernet bus communication technology, several calorimeters can be controlled by one PC, no interference between each other.
② Strong data processing capability, statistics report and printing function.
③ Capable of connecting with network and balance by RS232 interface.
