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

Photoconductive cells are light-sensitive resistors, in which resistance decreases with an increase in light intensity when illuminated

Material testing services test, analyze, and certify a wide range of materials for purity, chemical compatibility, and environmental impact.

Disposable primary batteries are replaced once the energy supply is depleted.

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

Specialty tapes and films use proprietary or patented technologies and constructions, and are designed for specific industries and specialized applications.
