UNI20+PPH500
Warmly welcome online / on-site meeting with us to show you around our factory and know each other better.
Introduction
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,thenuselinearrelationofpHvalueofthemeasuringsolutionandpotentialofworkingbatterytorealizetheon-line monitoring.
What is pH sensor?
A water pH sensor is an essential device used to measure the acidity or alkalinity of water. The pH scale, ranging from 0 to 14, serves as a numerical indicator of water's chemical nature. A pH value of 7 represents neutrality. Values below 7 signify acidic conditions, while those above 7 indicate alkalinity.
Main Features
² Good repeatability and stablity.
² Simple cleaning and activation,quite high balance speed.The function of automatic temperature compensation.
² Optional analog-digital conversion module to achieve digital signal output,high anti-jamming capacity and far distance transmission .
² Optional analog-digital conversion module to achieve standard digital signal output(RS485),can achieve integration and networking with other equipment without controller.
² Quick and easy field installation,plug and play.
² Sensor power supply positive and negative reverse connection protection
² Sensor RS485 A/B terminal is connected to the power supply protection
² With time display, data storage and historical data viewing function;
² Optional data wireless transmission module.
Application
² 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.
² PH online monitoring of industrial process water and in wastewater treatment process.
