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

Electronic enclosures and instrument enclosures house electronic components and instruments. They are usually designed for handheld or desktop applications

Semiconductor metrology instruments are designed for wafer and thin film in-line inspection after semiconductor processing. They include capacitance gages, C-V systems, electron beam probes, ellipsometers, interferometers, I-V system, magnetometers, optical systems, profilometers, reflectometers, resistance probes, RHEED systems, and X-ray diffractometers.  

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

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

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

Humidity measurement instruments test for absolute humidity, relative humidity, or dew point in air

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

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

Vibration instruments are used for measuring, displaying and analyzing vibration. Typically these instruments comprise a transducer, data acquisition and either a local display or some sort of output to a computer or another instrument

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
