Which light meter should I rent: a standard lux meter like the LT300 or a UV meter like the ILT2400?
Rent the LT300 (or similar lux/footcandle meter) for visible lighting surveys—workplace illumination, compliance checks, and lighting design. Rent the ILT2400 (or similar UV meter) when you need to measure UV intensity, specifically for UV-C disinfection verification, UV curing, or UV safety assessments. The two instruments serve completely different purposes and aren’t interchangeable.
What's a common reason light meter data gets challenged later?
The most common reasons are: not documenting measurement locations and conditions, not using a cosine-corrected detector when required by the standard, not accounting for lamp warm-up time, and using a meter whose spectral response doesn't match the task (e.g., using a standard lux meter for UV measurement). Always document the measurement grid, instrument details, and conditions so results can be reproduced or verified.
When do wavelength and detector type matter most?
They matter most in UV work. For UV-C, curing, or specialty lamp applications, the customer needs to confirm the wavelength range and whether the job needs spot intensity or time-integrated dose—not just a generic "light reading."
What should I confirm before renting a light or UV meter?
Confirm the source type, expected wavelength, distance from source, measurement geometry, and whether the customer needs spot checks, logging, or dose calculations. Those details usually determine the correct probe and meter combination.
How do I make light readings more repeatable from one location to the next?
Keep the sensor angle, distance, and position consistent, avoid shading the sensor with your body, and document the setup. Small geometry changes can affect the result more than people expect.
What's the first decision when renting a light meter: visible light or UV?
Decide whether you're measuring visible light (for workplace illumination, safety lighting, or lighting design) or UV radiation (for UV-C disinfection verification, UV curing, or UV safety assessments). These require completely different instruments—a lux/footcandle meter for visible light, a UV meter calibrated for the relevant UV band (UV-A, UV-B, or UV-C) for ultraviolet work. The two are not interchangeable.
