New products

New instruments are released when a quantity becomes measurable that was not before, not on a calendar. Tell us the quantity you are watching and we will tell you when something measures it better.

Not sure which group measures your quantity?

Describe it in your own words: the thing you need a number for, and how good the number has to be. An engineer will point you at the right group.

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.
