Geophysical instruments are used for geological study, including rock and soil mechanics, core analysis and surveys of the earth

Navigational instruments and avionics include GPS devices, compasses, chronometers, radar units and other instruments for orientation, relative position and absolute position (longitude / latitude

Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point.

Linear velocity sensors measure the linear velocity of an object using either contact or non-contact techniques.

Interferometers measure distance in terms of wavelength and determine the wavelengths of light sources.

Flaw detectors are nondestructive testing instruments that can detect or measure defects in raw materials or finished products

Signal generators and waveform generators are used to test and align all types of transmitters and receivers, to measure frequency and to generate a signal, waveform or noise source. Signal generators can use AC energy, audio frequency (AF) and radio frequency (RF) to function.

Towers, poles and support structures elevate, support and/or position personnel and equipment such as antennas, lighting, surveillance cameras or sensors, wind turbines, weather instruments, and power lines

Dry material (powders) level sensing devices are used to measure levels of solid, dry materials in either continuous or point values represented with various output options.

Liquid level sensors are used to detect liquid levels or interfaces between liquids such as oil and water or liquids and solids. 

Level transmitters or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space. For each measurement, they provide an electrical output that is proportional to the input level.

Optical scanners are motorized mirror mounts and system used in scanning applications.

Thickness gages are used to make precise dimensional measurements on a wide variety of coatings and materials including steel, plastic, glass, rubber, ceramics, paint, electroplated layers, enamels, etc

Charge coupled device (CCD) cameras contain light-sensitive silicon chips that detect electrons excited by incoming light. They also contain micro circuitry that transfers a detected signal along a row of discrete picture elements or pixels, scanning the image very rapidly. CCD cameras use two-dimensional CCD arrays with many thousand of pixels.

Non-destructive testing (NDT) services use test methods to examine an object, material or system without impairing its future usefulness.
