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

Leak testing equipment is used to measure the escape of liquids, vacuum or gases from sealed components or systems.

Strain gauges are measuring elements that convert force, pressure, tension, etc., into an electrical signal.

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

Level gauges are industrial meters used to determined the level of a liquid in a fixed storage or process tank

Vacuum gauges are devices for measuring vacuum or sub-atmospheric pressures

Analog pressure gauges are mechanical devices that include bellows, Bourdon tubes, capsule elements and diaphragm element gauges

Pressure gauges are used for a variety of industrial and application-specific pressure monitoring applications.  Uses include visual monitoring of air and gas pressure for compressors, vacuum equipment, process lines and specialty tank applications such as medical gas cylinders and fire extinguishers

Digital pressure gauges use electronic components to convert applied pressure into usable signals. The gauge readout has a digital numerical display

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.

Plug and pin gauges are used to compare hole and slot dimensions or locations to specific tolerances. This product area includes go gauges and no-go gauges. 

Metal sheet is metal or alloy stock supplied or available in the form of sheet or foil. Metal sheet has a thickness between 0.006" and 0.250", and is 24" (609.6 mm) or more in width.

Noncontact infrared temperature sensors absorb ambient infrared (IR) radiation given off by a heated surface. They are used in applications where direct temperature measurement is not possible.

Thread gages are dimensional instruments for measuring and/or verifying thread size, pitch or other parameters.

Air gages use pneumatic pressure and flow to measure or sort dimensional attributes.
