Batteries
Our products are widely used in the evaluation, materials development, shipping inspections, maintenance, and reuse of secondary batteries such as lithium-ion batteries.
- Typical setting

Which cells are good, which are drifting, and can you tell in the time the line allows?
These are the measurements that decide the answer, and the ones most often taken badly.
Internal resistance in the milliohm and microhm range, measured through contact resistance that is larger than the signal.
Sorting speed at shipping inspection where every extra second is a unit of capacity.
Grading used cells for reuse when their history is unknown.
Electrode and electrolyte materials characterized by impedance rather than by guesswork.
Where the measurements are taken
Internal resistance and open-circuit voltage
Battery / ESS
A cell degrades in its internal resistance long before it degrades in its voltage.
Component impedance at the working frequency
Production line
A part in tolerance at 1 kHz can be out of tolerance where it will actually be used.
Withstand voltage, insulation and leakage current
Safety test bench
The test that decides whether a finished product is allowed to leave the building.
Electrical Safety Testers, Hipot / Insulation / Leakage Testers
Temperature and humidity over long periods
Environment
An electrical drift with no recorded temperature beside it is a number without a cause.
Instruments used in batteries
Bring us the batteries measurement you are stuck on.
Describe the installation and the quantity. We will say which instrument group measures it and what the measurement actually needs to resolve.
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.
