UV Radiometers & UV Light Meters: Rent or Buy

No. The ILT2400 ships with UV probes only, so it can't read lux or footcandles. For walkway, task or general lighting levels, rent the LT300 light meter.

Use the XSD140T254 probe (249–259 nm, centered on 254 nm) to check germicidal UV-C lamps. It has a low-profile housing for tight clearances and reads up to 2 W/cm². Use the SED005/WBS320/W probe (250–400 nm) for broadband UVA/UVB sources such as UV curing lamps; it reads up to 1 W/cm². If you need both, rent the kit with both probes. Tell us your wavelength range when you order.

Turn on Integrate mode. The ILT2400 adds each reading to a running total once per second, so W/cm² becomes J/cm² (dose). Set the display units to the probe's calibrated light-level units first.

Yes. The meter and probes come with ISO 17025, NIST-traceable calibration certificates.

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.
