Grounding rods and lightning protection systems provide reliable electrical connection to the earth or ground and can vary from simple copper rods to sophisticated electrolytic rod systems with active soil moisture replenishment

Ground resistance testers are devices that are used to measure and test electrical grounding systems

Filtration media and elements are designed to remove suspended particles from a process stream. This product area includes bulk filter media, cartridges, housing-only products, and housing and filter assemblies. 

Non-destructive testing (NDT) conductivity meters and resistivity meters are devices for measuring electrical conductivity and/or resistivity of solid media to determine the characteristics of its constituent materials.

GPS chips compare signals from several geo-positioning satellites to determine position on the Earth's surface. GPS is an acronym for global positioning system

Liquid filtration elements are used to remove impurities from liquids. They are used in water treatment systems and fluid processing applications

Surveying instruments are used for the accurate measurement of features, orientation and absolute positioning of large scale objects in engineering, construction, mapping, industry, defense and other applications.

Specialized electromagnetic sensors and instruments are proprietary electrical and electromagnetic sensors and instruments not explicitly listed elsewhere.

Specialty filtration and separation equipment includes specialized or proprietary products and accessories for filtration and separation.

Industrial filtration equipment is used to filter, thicken or clarify a mixture of different elements.

Power resistors are used in power generation and distribution, high-voltage applications, control systems, and other power system applications. They include load banks, grounding resistors, and dynamic braking resistors

Grounding indicators are used to monitor and verify the presence of grounding systems

Gas filtration elements are designed to remove particulates from a gaseous process stream. They are used in natural gas processing systems and gas extraction applications

Heat pumps are reverse cycle air conditioners. They use a compression cycle system to supply heat or remove heat from a temperature-controlled space

DC motors are most commonly used in variable speed and torque applications. They include brushless and gear motors, as well as servomotors.
