The UV radiation emitted by medium-pressure lamps has a very broad spectrum, and must be measured with radiometers designed to measure the entire spectrum of UV radiation, or specific ranges.

Low-pressure mercury lamps have lower emission levels, requiring more sensitive measuring equipment.

You’ll find these types of measuring device under “Measuring UV lamps”.

UV LED emitters emit at very narrow wavelength peaks of around +/-5 nm. You’ll find these devices under “LED UV measurement”.

All radiometers have a calibration validity period of 6 to 12 months.
