Ph Meters
A pH meter consists of three essential parts: a pH measuring electrode, a reference electrode and a high input impedance meter. The reference electrode has a known, constant and stable potential.
The pH electrode can be considered as a battery, with a voltage that varies according to the pH of the measured solution. The pH-determining electrode is a hydrogen ion sensitive glass bulb, with a millivolt output that varies according to alterations in the relative concentration of hydrogen ions inside and outside the bulb. The output of the reference electrode does not change with the activity of hydrogen ions. The pH electrode has a very high internal resistance, which makes it difficult to measure voltage variation with pH. Therefore, the impedance of the pH meter input and the dispersion resistances are important factors.
Types of Ph Meters Your Laboratory may need
Portable
Portable pH meters are essential tools for accurately measuring the acidity or alkalinity of a substance on the go. With advancements in technology, portable pH meters have become more compact, user-friendly, and reliable. These devices are ideal for fieldwork, outdoor research, or any situation where mobility is required. Kalstein offers a wide range of portable pH meters that guarantee precision and ease of use, allowing scientists and researchers to obtain accurate pH measurements with convenience.
Our portable pH meters under the category of Medidores de pH ensure high performance and durability, providing accurate readings in various environments.

Table pH meters
The pH Meters category includes a wide range of tools essential for measuring the acidity or alkalinity levels of various substances in laboratory settings. One of the subcategories within pH Meters is “Sobremesa,” which translates to “Benchtop” in English. Benchtop pH meters are designed to be placed on a table or workbench, providing easy access and convenience for conducting pH measurements. These devices are user-friendly and come in compact sizes, making them suitable for smaller laboratory spaces.
In the Sobremesa subcategory, customers can find a selection of high-quality benchtop pH meters with advanced features such as automatic calibration, data logging capabilities, and compatibility with various types of electrodes. These instruments are ideal for researchers, scientists, and professionals who require accurate and reliable pH measurements for their experiments or analyses. With their robust designs and precise measurement capabilities, Sobremesa pH meters from Kalstein offer an excellent solution for achieving consistent and precise pH results in laboratory environments.
