Automatic box body cleaning function. Different nature of the gas environment replacement and misoperation into the water, oxygen fast box body automatic cleaning. Box automatic cleaning valve to the box body pipeline integration using KF25 with steel wire pipe firmly connected to the external interface KF25 Pagoda connector.

III. Main technical parameters

1. Water analyzer, (imported from abroad) brand material: British MICHELL / (in accordance with the customer's use of environmental decisions)

Non-domestic or domestic assembly, third-party data to ensure credibility.

1) Measuring range: 0-1000ppm

2) Accuracy: ±1% ppm

3) Display: The output of the analyzer is connected to the PLC, the detection value is displayed on the touch screen, and the alarm value can be set.

4) Control: The gas circulation system can be controlled according to the user's setting to realise the circulation drop.

5) Environment: -10℃ -50℃
