Calibration of EIT instruments

EFSEN UV & EB TECHNOLOGY serves as the European Centre for calibration of EIT instruments and is officially certified to perform calibrations in accordance with EIT standards.

Our Holte, Denmark facility is equipped to perform calibrations, and our team has received training from EIT to conduct calibrations and issue certificates in accordance with EIT standards.

Note: Instruments submitted for calibration after Wednesday, March 25th will be returned in week 15 due to the Easter holiday, provided no repair is required.

Want to submit your instrument for calibration?

Our usual turnaround time is 1-2 weeks from the date the instrument is received at the EFSEN facility, assuming standard repairs have been pre-approved.
If repair approval has not been obtained in advance, additional processing time may be extended.

We calibrate the following EIT instruments

Our calibration procedure

Broadband instruments are calibrated using an arc lamp, unless a different UV source is specifically requested by the customer. LED instruments are calibrated using an LED source. If you have special requirements, these can be arranged for an additional fee.

We provide calibration services for standard high-power instruments in the UVA, UVB, and UVV range (100mW/cm²–10W/cm²) as well as the UVC range (10mW/cm²–1W/cm²).

We do not calibrate Lower Power (LP) and Midrange (MR) instruments at our Holte, Denmark facility. However, if you send your instrument to us, we will manage the necessary arrangements to get it calibrated.

Call for calibration – Free reminder service

EFSEN calls all instruments for calibration before they are due for next calibration. Reminders are sent out by e-mail to the person responsible. 

If you do not want to be part of this free reminder service, please send an e-mail to efsen@efsen.dk.
