5. Display system

SIEMENS, Germany, unit control using Siemens PLC touch screen. Both Chinese and English can be switched.

6. Water analyzer, (imported from abroad) brand material: British MICHELL/ (according to customer use environment decision) non-domestic or domestic assembly, third-party data to ensure credibility.

1) Measurement range: 0-1000ppm

2) Accuracy: ±1% ppm

3) Display: The output of the analyzer is connected to 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 Settings to achieve circulation drop.

5) Environment: -10℃ -- 50℃

7. Oxygen analyzer, (imported from abroad) brand materials: AVCRAY (in accordance with the customer's use environment) non-domestic or domestic assembly, third-party data to ensure credibility.

1) Measurement range can be set: 0-1000ppm

2) Environment: -10℃ -- 50℃

3) Accuracy: ±1% ppm

4) Installation position: The oxygen sensor is installed on the box. Regardless of gas circulation or not, the oxygen sensor can continuously detect the atmosphere in the box and display the oxygen content in the glove box.

5) Sensor: electrochemical material battery, its advantages are accurate zero, small drift, avoid other battery materials easy to be corroded; Low replacement cost (only oxygen battery replacement).

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