Seaward has been designing and manufacturing high-voltage test equipment for over 37 years and continues to innovate and bring the best instruments to market. Choose from phase sticks, safe discharge bars, voltage indicators and more. Whatever your high-voltage requirements, LHM Instrumentation has a solution for you.

There are a number of methods that can be used, but by far the best measurement method for low resistance values below 100Ω is the 4-wire technique (also known as the Kelvin method). All LHM Instrumentation low-resistance ohmmeters use this method to ensure measurement accuracy. The principle of this method eliminates any additional resistances due to the resistance of the test lead.

Performing electrical safety tests is seen as an absolute must. Conducting the required tests in accordance with the appropriate safety standard can demonstrate compliance with legislation.
Portable device testing (PAT testing) is essential for electrical safety in any workplace.

The digital current clamp is a workhorse for everyday use. Our current clamps are designed for noise-free, reliable measurements. The current clamps offer advanced performance and are designed as easy-to-use and portable instruments, perfect for tight, compact spaces or reading readings from panels that are out of reach or from extra-thick conductors.

Portable oscilloscopes open up areas for you where standard table oscilloscopes fail, for example harsh, dangerous and dirty industrial environments.
These handheld instruments combine the performance of a table oscilloscope with a multimeter and paperless recorder for installing, commissioning and maintaining industrial and electronic equipment in the field.

Whether you are in an industrial plant, production facility or utility, our grid power quality and energy management instruments are designed to map the grid power quality and energy data you need for best performance and reliability. These instruments make it easy to detect your power quality and energy efficiency problems, and allow efficient recording and analysis.

Digital multimeters are undoubtedly the most important measuring instruments for troubleshooting. LHM Instrumentation therefore offers you a very wide range of multimeters that provide accurate, consistent and reliable measurements. Enter everyone's budget and problem we have a solution.

Modifying or troubleshooting an existing electrical installation is sometimes not easy.
With LHM Instrumentation's cable testers and tracers, you can quickly detect the location of your cables or according to as well as determine at what distance there is a cable problem.

Whether working on motors, generators, cables or switchgear, LHM Instrumentation's digital insulation resistance testers deliver noise-free, reliable results. Our insulation tester have advanced functionalities and are designed for optimum ease of operation.

Safety and performance are two of the most critical requirements any electrical system must meet. Good quality insulation, a functioning earthing system and active protection ensure the safety of people, electrical systems and buildings.
At LHM Instrumentation you will find a wide selection of Installation Testers
