KVA meters measure the apparent power of AC devices in kilovolt-amperes (KVA). Apparent power is the combination of a circuit’s true power and reactive power.

Total organic carbon (TOC) analyzers measure the amount of total organic carbon present in a liquid sample

Water quality photometers and colorimeters are ion-specific computer-interfaced probes designed to determine the concentration of a solution from its color intensity.

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

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.

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

Audio analyzers measure the noise and audio spectrum of output from an amplifier or a stereo.

Casters are complete wheel and horn assemblies which, when attached to a piece of equipment, allow it to move.

Intrinsic safety (IS) barriers are devices that limit the current, voltage, and total energy delivered to a sensor in a hazardous area or flammable environment in order to prevent an explosion

Harmonic filters isolate harmonic current to protect electrical equipment from damage due to harmonic voltage distortion. They can also be used to improve power factor, and are sometimes called line reactors, load reactors, line load reactors, and line/load reactors.

Laboratory and calibration gases are specialized for use as laboratory standards, as well as for detection, sample preparation, environmental monitoring and analysis applications.

Energy meters measure the total energy of a single pulse and optical power meters measure the average power of a continuous light beam

Property testers are used to determine various physical properties of samples, including distillation, vapor pressure, and cloud, flash, freezing, melting, or pour point.

BTU meters measure the energy changes in liquid or gas flows in British thermal units (BTU).

Parking control systems and products are used in automobile parking enforcement and management. Examples include parking meters, ticket dispensers, toll barriers and parking partitions.
