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

Instrument calibration services test equipment and calibrate them to various standards.  

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

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

Density and specific gravity instruments are meters used to determine density and specific gravity

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

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

Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 

Weather instruments are designed to measure one or multiple components of weather including wind speed and direction, rain or snow fall, solar radiation, temperature, pressure and humidity

Analytical laboratory services detect, classify and/or assay chemical, material, biological, geological and environmental samples

Turbidity instruments measure the average volume of light scattering over a defined angular range. Both particle size and concentration of suspended solids as well as dissolved solids can affect the reading

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

Solar radiation instruments measure the spectral range of radiation, including global solar radiation (sun + sky), net radiation (incoming solar - reflected solar) and the photosynthetic light spectrum

Dissolved oxygen meters are analytical instruments that are used to measure the amount of oxygen dissolved in a liquid sample

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