Measurement Principle:
PPH-500 pH sensor is a combination electrode combined precious metals indicator electrode with reference electrode. Firstly measure the potential difference of working battery made up of measuring electrode and reference electrode in the solution,then use linear relation of pH value of the measuring solution and potential of working battery to realize the on-line monitoring.
Features:
1. Good repeatability and stablity. Suitable for fresh water and sea water testing, PH 0-14pH.
2. Simple cleaning and activation,quite high balance speed.The function of automatic temperature compensation.
3. Optional analog-digital conversion module to achieve digital signal output,high anti-jamming capacity and far transmission distance.
4. Quick and easy field installation,plug and play.
Applications:
1. PH online monitoring in technological process of inlet/outlet of sewage treatment plant,sedimentation basin and biochemical reaction basin and so on.
2. PH online monitoring of municipal water supply industry,surface water and aquaculture and so on.
3. PH online monitoring of industrial process water and in waste water treatment process.
