Vector network analyzers (VNA) measure the complex transmission and reflection characteristics of two-port devices in the frequency domain.

Audio Analyzers

(44 companies)
Audio analyzers measure the noise and audio spectrum of output from an amplifier or a stereo.
Optical spectrum analyzers (OSA) can divide a lightwave signal into its constituent wavelengths. This means that it is possible to see the spectral profile of the signal over a certain wavelength range.

Residual Gas Analyzers

(73 companies)
Residual gas analyzers (RGAs) identify the gases present in vacuum environments.

Laser Beam Analyzers

(40 companies)
Laser beam analyzers are used to determine the quality of a laser beam.
Scalar network analyzers measure the amplitude portion of scattering or S-parameters, reflection and transmission coefficients between the incident and reflection waves that describe a device’s behavior under linear conditions at the microwave frequency range.

Viscometers define viscous properties of a fluid at ambient or defined temperatures.
Power quality analyzers measure and monitor electrical power parameters to avoid disturbances, track steady-state variations, and ensure the reliability of power distribution systems.
Calorimeters and thermal analyzers contain a heat source that can deliver a heat flux, at a distinct temperature, into a sample, and a temperature-measuring device that can read the resultant change in temperature.
Total organic carbon (TOC) analyzers measure the amount of total organic carbon present in a liquid sample.

Oil and Water Separators

(410 companies)
Oil and water separators (oil-water separators, oil water separators) are remediation devices that separate oil from water and/or wastewater. This product area includes both aboveground and underground systems for the containment and treatment of oil-contaminated water.
Volatile organic compound (VOC) analyzers are used to detect concentrations of heavy hydrocarbons in gas or liquid media.
Petroleum products and mineral oil products include substances such as fluids and greases.
Network analyzers and protocol analyzers are test equipment used to troubleshoot and analyze network problems.
Surface area and pore size analyzers are used to measure the surface area and pore size of a sample.
