G & R Labs

Company record

G & R Labs produces a line of ultraviolet (UV) light meters that incorporate interchangeable probes and deliver probe‑to‑probe repeatability better than 1 percent. Its portfolio includes cosine‑response probes capable of real‑time measurement across a broad spectral range, with individual probe options covering wavelengths of 173 nm, 193 nm, 220 nm, 248 nm, 254 nm, 260 nm, 280 nm, 310 nm, 365 nm, 400 nm, 420 nm, 436 nm and 540 nm. Power requirements are satisfied by an AC charger operating from 90 V to 240 V at 47–63 Hz, and the devices hold UL, CE and TUV certifications. In addition to UV meters, the firm offers solar meters that measure spectra from 0.3 µm to 1.1 µm, as well as dedicated UV‑curing meters. Calibration services are also provided to ensure ongoing accuracy.
