HACH Digital Differential pH/ORP Sensor
Differential pH sensors from Hach® use patented technology to ensure reliable measurement and long-term dependability. Our differential pH sensors come with replaceable salt bridges that hold higher volumes of buffer and protect their reference electrodes. Choose the body material of your differential pH sensor, mounting type, and electrode type depending on your desired usage.
Sensors & Probes for pH and ORP measurement
Elevate your pH and ORP measurements with Hach®'s line of trusted pH sensors and probes. Our patented diff erential electrode measurement technique guarantees precision and reliability, minimizing downtime and maintenance compared to traditional pH sensors and probes. By seamlessly integrating with Claros, Hach's revolutionary Water Intelligence System, our pH sensors gain real- time access to instrument data and process management — anytime, anywhere.
pH Sensors with Less Maintenance
We built our pH sensors to minimize the dilution of internal standard cell solution. This results in a longer- lasting pH sensor that you can trust.
pH Probes and Sensors Made to Last
Because of our unique replaceable salt bridge design, you can trust our pH sensors to last for longer in harsh process conditions.
