pH Probe

1. pH/ORP-1110/1120 series integration type sensor with wide compatibility;

2. The liquid junction is stronger than other sensors, the Gel won’t separate when under high temperature or negative pressure;

3. The sensor with gel electrolyte, anti-pollution Teflon ring liquid junction;

4. A new type of glass membrane is used with a fast response;

5. Platinum ring ORP electrode enables REDOX reaction stability;

6.NPT3/4″ thread， it can be Compatible with all the online pH/ORP sensor installations;

7. Works with P34A pin valve flow adjustment device. Stable measurement to meet requirements of ultra water measurement;

8. P34A can provide pressure-bearing, sample testing measurement.

NOTE:

1. Pressure-bearing operation-maintain the operating mode in the pipeline

2. There is no need to shut off the flow.
