Ultra-high insulation resistance and volume resistivity

Super Megohmmeters

Insulation resistance far above the range of a field tester, for materials and components where the leakage is the specification.

What this group is for

Written as engineering fact. Nothing on this page states a specification the manufacturer has not supplied.

  • Measurement ranges reaching far beyond a portable insulation tester, into the region where materials are characterized rather than merely passed.

  • Guarded measurement that keeps surface leakage out of the volume resistivity reading.

  • Stable, repeatable readings at very low currents, where noise and settling time are the real adversaries.

  • Electrode fixtures for measuring sheet and bulk material to a standard method.

Highlighted models

Model data to be supplied

Specific Super Megohmmeters models are quoted against the application, because the right one depends on the range you need to resolve and the conditions on site.

Tell us what you are measuring and we will name the models that cover it, with the ranges and accuracy classes written out in full.

Where it is used

Four situations this group is bought for, and the points on a real installation where it is connected.

  • Volume and surface resistivity of insulating materials.
  • Leakage evaluation of capacitors and electronic components.
  • Insulation development and incoming material qualification.
  • Cleanliness and contamination studies on assemblies.

Typical measurement locations

Insulation resistance of windings

Transformer

Insulation does not fail suddenly. It trends, and the trend is only visible if someone measured it last year too.

Super Megohmmeters: which one fits your measurement?

Give us the quantity, the range you need to resolve and the conditions on site. We will name the models that cover it and say plainly where they stop.

What has to be true inside the company

Four criteria of innovation, and the reason a measurement can be trusted outside it.

Increasing customer value

Production system

A production system built so that a measurement need turns into a delivered, calibrated instrument without the customer absorbing the delay.

Delivering peace of mind to customers

After-sales service

An instrument is only as good as the number it still reports in year five. After-sales service exists to keep that number trustworthy.

Pursuing productivity and precision

Manufacturing capabilities

Precision is a manufacturing capability before it is a specification. It is held in the process, not promised in the catalog.

Creating new customer value

Collaborative development of new products

When a field has no instrument for the quantity it needs to see, the instrument gets developed with the customer who needs it.
