PH-113 Portable pH/Temperature meter High-precision; small size; simple, easy accessibility and the operation panel that makes machines easy to understand, easy to operate. Automatic temperature compensation, with the help of the temperature probe, can automatically correct the impact of temperature ...
This guide explains both practical and theoretical requirements in depth so that the measuring principle is understood and an accurate measurement made possible.Read more pH Calibration Guide pH systems with Intelligent Sensor Management (ISM) drastically minimize the maintenance and workload, meaning far...
And, yes... I have seen the cheap, widely available metal probe pH meters online and at the local gardening supply shop. I am just curious what principle is at work with these and what trade-off is being made as all of the industrial, or lab grade probes use glass electrodes. ...

Table 1. Critical micelle concentration (CMC) values calculated by spectrofluorimetry using pyrene as fluorescent probe as a function of pH (6.0, 7.0, 8.0, and 9.0), temperature (25 and 50 °C) and buffer concentrations (50 mM, 250 mM, respectively). Number of repeats, n = 3. Empty Ce...
Basic Principle of pH Electrode The polymer filling makes the reference junction potential very stable. The diffusion potential is very stable; large-area diaphragm surrounds the glass diaphragm bubbles, so that the distance from the reference diaphragm to the glass diaphragm is...

the pH values were measured with a standard laboratory pH meter and no pH-dependent dyes were used, which are not designed for use in these extreme temperature conditions and are not compatible with measurements in the entire pH range. However, since measurements using a pH meter are not possi...
Principle In PH measurement, the used electrode is also known as the primary battery. The primary battery is a system, whose role is to transfer chemical energy into electrical energy. The voltage of the battery is called the electromotive force (EMF). This electromotive force (...
