Sight windows are an effective and economical way of viewing tank, pressure vessel and piping systems interiors. They are also referred to as sight glasses

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

Sight flow indicators provide a quick, reliable and economical way to verify the flow of fluids through industrial process lines

Levels are mechanical or electronic tools that measure the inclination of a surface relative to the earth's surface

Magnifiers are inspection instruments that are used to magnify a product or part detail via a lens system.

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.

Tilt sensors, switches and inclinometers generate an artificial horizon and measure angular tilt with respect to this horizon. They are used in cameras, aircraft flight controls, automobile security systems, and special switches.

Lasers are devices that produce intense beams of monochromatic, coherent radiation. The word “laser” is an acronym for Light Amplification by Stimulated Emission of Radiation.

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

Glass fabrication services is the manufacturing of glass parts and assemblies using blowing, casting, extrusion, drawing, pressing, heat shrinking or other fabrication processes.  

Glass materials have a random, liquid like (non-crystalline) molecular structure. They are heated to a temperature sufficient to produce a completely fused melt

Liquid level switches are used to detect specific liquid levels or interfaces between liquids. These level measurements are indicated via an electrical switching action

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

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

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
