How Often To Calibrate A pH Meter?
To ensure accurate pH measurements, it's important to calibrate your pH meter regularly. The frequency of calibration depends on the specific pH meter you're using, how often you use it, and the precision required for your measurements. However, as a general guideline: Frequent Use: If you use your pH meter daily or frequently, it's recommended to calibrate it before each use or at least once a ...

pH measurement: Six technical tips
The pH value is one of the most important and therefore also one of the most frequently measured quantities in analytical chemistry. Sometimes, a simple pH test strip is sufficient for making a rapid check; precise pH meters are, however, required whenever accurate measuring results are needed. Such a pH meter is available in nearly every laboratory and is generally ready for use at a moment's ...

New ISFET pH meter PCE-ISFET
The new PCE-ISFET pH meter from PCE Instruments has been designed for food applications. The glass free electrode makes it particularly safe to use in food production as no glass splinters can get into the food if the electrode breaks. Unlike glass pH electrodes, ISFET pH sensors are highly resilient and do not require wet storage. They give reliable results under tough conditions. The PCE-ISFET ...

pH Electrode Architecture
A pH Electrode can be compared to a battery in that an electrical voltage is generated between two points that is a function of water chemistry. In the case of a pH electrode the voltage potential is a function of the acidity or alkalinity of the solution in which it is immersed. Note: The terms pH electrodes and pH probes are often used synonymously, despite the fact that there are differences. ...

How can I measure the pH of food?
Measuring pH in food is a useful indicator of consistency over batches for quality control but can also be used to monitor foods where the pH changes over time – for example in yogurt production, brewing or to test the freshness of foods. Standard pH electrodes will often struggle when used in food samples, as the reference junction becomes blocked the reaction time will get slower and ...

Accuracy of different sensors for the estimation of pollutant concentrations (total suspended solids, total and dissolved chemical oxygen demand) in wastewater and stormwater
Many field investigations have used continuous sensors (turbidimeters and/or ultraviolet (UV)-visible spectrophotometers) to estimate with a short time step pollutant concentrations in sewer systems. Few, if any, publications compare the performance of various sensors for the same set of samples. Different surrogate sensors (turbidity sensors, UV-visible spectrophotometer, pH meter, ...

How should I clean a pH electrode, or revive a damaged electrode?
Traditional glass pH electrodes are very delicate and need regular care to keep them in good working order. If your electrode has been damaged by exposure to incompatible chemicals such as proteins, heavy metals or sulphides, you may be able to clean and revive it using specialized cleaning solutions… pH electrodes that have a single junction are particularly susceptible to damage, and ...
