ComPhysics Green UV

IMPORTANT: This app requires the ComPhysics CP-UV01 UV Indicator and CP-UV01-SA smartphone accessory. Without the dedicated optical hardware, the displayed values are not valid UV measurements. ComPhysics Green UV uses the iPhone camera to analyze the green visible emission produced by the CP-UV01 optical system. It provides a relative UV signal called CRU (ComPhysics Relative UV) and helps you compare conditions, save results, and observe changes over time. KEY FEATURES • Real-time CRU display • Movable circular Region of Interest • Reference-versus-sample comparison • Relative effective UV transmittance and blocking display • Time recording with graph • Photo and reading capture • Sample names and notes • Local export of CSV, JSON, JPEG, and PDF files • Optional location and device-orientation data for records • Korean, English, Japanese, and Simplified Chinese PRIVACY Camera frames and measurement data are processed on the device. The app does not include advertising or third-party analytics SDKs and does not automatically upload measurement data to ComPhysics. Files leave the app only when you choose to share or export them. MEASUREMENT NOTICE ComPhysics Green UV is a relative comparison tool. It is not an absolute UV irradiance meter, certified spectroradiometer, medical device, safety-certification system, or official spectral transmittance instrument. Results depend on the iPhone model, selected camera, settings, accessory alignment, ambient light, distance, angle, source spectrum, and measurement geometry. A low reading does not prove that a UV source is safe.
