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

Digital panel meters measure and display processes and electrical variables via an alphanumeric digital readout

Moisture meters are used to measure the moisture content in bulk solids, liquids and gases

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. 

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

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.

Digital bargraphs measure process and electrical variables such as pressure, flow, temperature, speed, current, and voltage. There are two main types of products: light emitting diode (LED) and liquid crystal display (LCD).  

Temperature indicators and temperature instruments are designed for temperature monitoring and analysis. These devices either come equipped with an integral sensor, or require sensor input.

Non-destructive testing (NDT) equipment is used to detect, inspect, and measure flaws, bond integrity, and other material conditions without permanently altering or destroying the examined part or product.

Property testers are used to determine various physical properties of samples, including cloud point, distillation, flash point, freezing point, melting point, pour point, and vapor pressure.

Web tension sensors are used to measure static or running tension in webs or sheets during the manufacture of textiles, paper, and other sheet materials.

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.

Level switches is a generic search form for devices that are used to detect liquid or powder levels, or interfaces between liquids. These level measurements are indicated via an electrical switching action.
