PRODUCT DESCRIPTION
The TH-254 is a dual-channel UV radiation meter built around a 254 nm narrow-band probe — the germicidal UVC wavelength. Four ranges from 199.9 µW/cm² to 19.99 mW/cm² cover everything from weak leakage checks to direct lamp output, with memory functions and RS232 output for recording results.
Fast 0.4 s sampling makes it practical for scanning lamp arrays and verifying sterilization dose across a surface.
