 pH Measurement Explained
 
All pH probes and sensors comprises of two main elements a glass sensing membrane electrode and reference electrode working together in a single unit measuring the hydrogen ion activity in an aqueous solution to determine it's acidity or alkalinity hence the term combination electrode, by measuring the voltage difference between the pH sensitive glass membrane and reference electrode which provides a known stable reference potential completing the electrical millivolt circuit proportional to the pH measurement value.

Epoxy Body
 
Robust industrial-grade single junction pH Probe with PTFE pellon diaphragm a highly-durable clog-resistant porous interface between the reference electrolyte inside the probe and the liquid sample being measured being unaffected by flow fluctuations and drift associated with contaminated sensors, built to withstand the rigors of continuous monitoring it provides a fast linear response an ideal reliable workhorse for processes such as chemical manufacturing where downtime for recalibration isn't an option.
 
 

The Right Junction for Every Application
 
     Single Junction Probes: The cornerstone of electrochemical analysis and economical choice for general-purpose applications designed to measure the oxidizing or reducing power of an aqueous 
      solution particularly favoured for their economical design and rapid response in harsh environments where contaminants are low and applications where rapid fluctuations must be caught in real-time
 
     Double Junction Probes: Engineered specifically for challenging environments the secondary internal junction adds an extra physical barrier to prevent the reference element from contamination
      of substances that contain heavy metals, sulfides and proteins significantly reducing the frequency of sensor replacement and minimising calibration drift.
