pH electrodes and oxygen reduction potential (ORP) electrodes measure the voltage across a circuit formed by the measuring metal half-cell and the reference half-cell

pH and oxidation reduction potential (ORP) instruments measure or monitor pH (relative concentration of hydrogen ions [H+] in a solution) as well as ORP

pH and ORP controllers monitor and can control the pH (acidity or alkalinity) and/or the ORP (oxidation reduction potential) of liquids involved in a testing or process application

Test equipment and instrument repair services test and repair industrial equipment and instruments. They specialize in the test and repair of acoustic and vibration equipment, electrical and electronic test equipment, laboratory equipment and instruments, inspection instruments or non-destructive testing (NDT) equipment, or specialty testing equipment and instruments.

Water quality testing instruments are used to test water for chemical and biological agents, and to measure variables such as clarity and rate of movement.

Corrosion and electrochemical instruments use a variety of methods to detect and measure corrosion and electrochemical conditions in plant machinery, field equipment, batteries, fuel cells, colloids, and other solutions or systems.

Conductivity meters, dissolved solids meters, and resistivity meters are analytical instruments that measure the conductivity, dissolved solids, and/or resistivity of a liquid sample.

Conductivity electrodes are devices that measure the salinity and conductivity of water samples.

Test equipment and instrument rental services rent or lease test equipment for electrical, electronic, vibration, acoustic, dimensional, NDT, analytical, environmental, process, EMI/RFI, and other specialty testing, measurement or inspection applications.

Dimensional gages and instruments provide quantitative measurements of product or component dimensional and form attributes such as wall thickness, depth, height, length, inner diameter (ID), outer diameter (OD), taper or bore.

Gas and air instruments detect, monitor or analyze gases present in an environment.

Non-destructive testing (NDT) equipment is used to detect, inspect, and measure flaws, bond integrity, and other material conditions without permanently altering or destroying the examined part or product.

Calibration instruments use electrical signals or physical quantities to calibrate sensors and meters. Devices that produce electrical signals can serve as precise meters for sensor calibration, or send output signals to other devices.

Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point.

Calibration and repair services for vibration, acoustic, electrical / electronic test, environmental, dimensional, NDT, analytical, process and other specialty instruments, sensors and related equipment.
