Calibration of Sensors

We offer traceable calibration of temperature sensors and have the necessary reference equipment down to -85°C and accuracies from ± 0.01°C.
We carry out traceable calibration of temperature sensors with documentation in our ISO quality system. Our measurement equipment is traceable according to Danish and international references.

Helium leak detection

If you have a leaking cooling or piping system, we might be able to help you find the hole/leak?

Contract work or rental basis

- We offer Helium leak detection as wage work, where there will be an amount for start-up and then we invoice on hourly rate plus consumption of helium and driving.

- It is also possible to rent a helium leak finder for larger tasks, where we take care of delivery, installation, training, consumption of helium and subsequent repatriation.

As a distributor of vacuum equipment from Agilent, we use their helium leak dector for the tasks. The equipment is an oil-free helium leak finder from Agilent model PD03 equipped with scroll and turbo pump with ultimate pressure 5x10-12 and can leak search on both pressurized items and under vacuum.

The shelters can be clarified as follows:

10-5 mbar l/s corresponds to a hole through 2 mm wall thickness of approx. Ø 0.006 mm, and 10-4 mbar l/s corresponds to that it will take approx. 2 min to form an air bubble in a pressure test under water.

Areas of application of Helium leak detection:

Accelerators, mass spectrometers, NMR, refrigeration systems, electron microscopes, vaporizers/coaters, freeze dryers, refrigeration systems, impregnation stands, vacuum fittings, piping installations, gas pipe systems, tanks and pressure vessels sintering furnaces? hardening furnaces, vacuum filling plants, etc.
