Liquid crystal display (LCD) modules are used at the component level in place of less efficient displays such as cathode ray tubes (CRTs). These modules do not include a housing and must be incorporated into a larger instrument or system

Bar graph arrays are light emitting diodes (LEDs) that are used for solid state metering in applications such as audio monitoring, telecommunications, and instrumentation

Vacuum fluorescent displays (VFD) provide high brightness, wide viewing angles, and relatively low cost

Graphing and visualization software visually present abstract scientific data. The programs take numerical data and create (render) images for analysis

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).  

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

Chart recorders and strip charts are data acquisition tools used to generate a plot, graph or other visualization of data versus time

Specialty lab and test equipment includes specialty or proprietary products and accessories related to laboratory testing.

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.

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

Level controllers monitor, regulate, and control liquid or solid levels in a process.

Level switches, all types, 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.

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 ammeters are instruments that measure current flow in amperes and display current levels on a digital display. These devices provide information about current draw and current continuity in order to help users troubleshoot erratic loads and trends

Computer-based instruments are part of a computer (a board, for example), or need to be connected to a computer in order to measure and display data
