Calibration request for UV measuring instruments – including third-party instruments

Which instrument would you like to have calibrated?

The type of instrument determines how we calibrate it and which details we need from you.

Radiometer with handheld unit Measuring instrument with its own display and one or more sensors. UV sensor with voltage or current output Sensor without its own display that delivers an analogue signal, e.g. for process monitoring. Spectroradiometer Instrument that measures spectral irradiance. It is calibrated with standard lamps across the entire spectral range.

Instrument details

We can calibrate almost any third-party instrument to the irradiance of a given lamp. To classify your instrument correctly, we need the manufacturer, the type and the number of sensors.

Manufacturer *

Type / model *

Serial number of handheld unit

Serial number(s) of sensor(s)

If there are several sensors, please enter all numbers, separated by commas.

Serial number

Device ID

Your internal inventory number or device ID. We will print it on the calibration certificate.

Number of sensors *

Each sensor is calibrated individually and receives its own values on the certificate.

Photos of the instrument

Optional, up to 3 images (JPG, PNG or WEBP, max. 10 MB each). A photo of the instrument and sensor head helps us identify your instrument quickly.

Lamp and spectral range

A calibration always applies to a specific lamp and a specific spectral range. We calibrate your instrument with the spectrum of the lamp you will later measure with it.

Lamp to be measured

Select a lamp from our spectral database. If your lamp is not in the list, please enter its manufacturer and type.

Photos of the lamp

Optional, up to 3 images (JPG, PNG or WEBP, max. 10 MB each). A photo of the lamp or its type plate helps us choose the right spectrum.

Standard lamps for the calibration: FEL lamp + deuterium lamp

We calibrate spectroradiometers with an FEL lamp (halogen standard lamp) and a deuterium lamp. Together they cover the UV, visible and near-infrared range.

Spectral range

nm

Optional, in nanometres, e.g. 315 – 400 nm for UVA: the range in which your instrument measures.

Typical irradiance

Optional. The value you usually measure at your system.

Type of calibration

Calibration *

DAkkS calibration according to ISO/IEC 17025 Accredited calibration in our own calibration laboratory with an internationally recognised certificate. Factory calibration Traceable calibration with a factory calibration certificate.

Adjustment (third-party instruments) *

Calibration with adjustment We adjust your instrument so that it displays correctly. As it is a third-party instrument, we need the manufacturer’s adjustment instructions. Calibration without adjustment We determine and document the deviation of your instrument and a correction factor. Your instrument remains unchanged.

Adjustment instructions

PDF, JPG or PNG, max. 10 MB. If you do not have the instructions to hand, you can also send them later by e-mail.

Example correction factor

Reference value mW/cm² Reading of your instrument mW/cm²

Correction factor: 1,03

In future, multiply the displayed value by this factor.

Previous calibration files

Optional, up to 5 files (e.g. .cal, .txt, .csv, .dat, .ini, .xml, .xlsx, .pdf, .zip; max. 10 MB each). This lets us adopt the format and wavelength grid of your instrument software.

Tolerance / statement of conformity *

On request, we confirm on the certificate whether your instrument meets a tolerance. You specify the tolerance – as required by ILAC-G8.

No statement of conformity

Additional services and delivery time

Linearity test In addition, we test the linearity of your instrument across several orders of magnitude of irradiance (source-addition method). This shows whether it measures correctly across the entire measuring range – not just at the calibration point.

Delivery time *

Standard: approx. 2 weeks Processing time from receipt of the instrument. Express: approx. 2–3 working days Priority processing for a surcharge.
