SE 554 Memosens pH/ORP Sensor

The special design provides high accuracy, stability, speed, and a long life cycle. Through 2 open junctions, the reference system is in direct contact with the measured medium. There is hardly any risk of contamination or blocking of the junction. The high content and special distribution of potassium chloride in the polymer reduces measurement disturbances which could be caused by liquid junction potentials.

Highly Accurate pH Probe System

Our pH Probe system is a revolutionary technology that can measure the acidity or alkalinity of a given liquid. This device is incredibly precise and reliable, allowing us to get accurate readings in real-time. The smart probe design allows users to monitor these levels with ease, while also reducing calibration time and cost. Additionally, data from multiple probes can be wirelessly transmitted over various distances with minimal lag time. With our unique pH Probe system, businesses are guaranteed more efficient sample handling for all their testing needs.
