PRODUCT DESCRIPTION
The TH-365 is a dual-channel UV illuminance meter with a 365 nm narrow-band probe — the standard wavelength for UV curing and black-light inspection. Three ranges up to 19.9 mW/cm², memory functions and automatic shutdown make it a practical bench and field instrument.
Its 0.4 s sampling supports quick pass/fail checks of curing lamps and inspection lights across a production line.
