Opsytec UV Meter Curelog Series

Optimize UV curing, disinfection, and quality control with Opsytec’s Curelog family. This combined page presents Curelog Base (entry-level, mobile) and Curelog Advanced Series (advanced with data logging, multi‑spectral capability, and ONE / LED / PRO versions). Select the model that fits your application: quick measurement without logging (Curelog Base) or deep process analysis with up to 2000 Hz sampling and up to 180 hours of recording (Curelog Advanced Series). Curelog Base is a compact UV dosimeter designed for peak irradiance and UV dose measurements. Intended for quick tasks in lab or production environments, it offers professional UV measurement in a slim, lightweight aluminum body. No onboard data logging is included.  Curelog Advanced Series is a multi‑range UV radiometer with onboard data logging and highly configurable sampling. Designed for UV curing, disinfection/sterilization, and lithographic applications, it supports 1–2000 Hz sampling and 5 minutes to 180 hours of recording. Multiple UV ranges (up to 4 simultaneously, depending on version) allow detection of critical profile changes, reflector contamination, and intensity shifts. With Curelog DOCK, peak irradiance and dose output can be transmitted to a PLC for automated pass/fail control. Full analysis is done through the PC software. Curelog Series uses radiometric (filtered‑photodiode) measurement, not spectral analysis. For full spectral characterization, Opsytec recommends UVpad spectroradiometers. Curelog Base Measures peak irradiance and UV dose Mobile, simple operation Curelog Advanced Series Data logging up to 2000 Hz Recording up to 180 h Measures up to four spectral ranges (depending on version) Compatible with Curelog DOCK for PLC integration (RS485/RS232) PC software for analysis, comparison and export Versions: Curelog ONE – One spectral range / Curelog LED – Optimized for 365, 385, 395, 405 & 450 nm (also measures UV) / Curelog PRO – Measures UVA, UVB, UVC, VISB (CIE classification) Both variants display peak irradiance and UV dose on screen.
