PRODUCT DESCRIPTION
The TH-340 is a professional UVA/UVB meter with a separated probe and a 290–390 nm sensor. Two ranges — 1999 µW/cm² and 19990 µW/cm² — handle both ambient monitoring and intense industrial UV sources, with 0.4 s sampling for quick surveys.
The separate probe reaches into curing chambers, welding areas and exposure equipment while the operator reads the meter from a safe position.
