Lutron Professional Grade SD Card Data Logging UVA and UVC Meter

The Lutron YK-37UVSD is a professional-grade, microprocessor-based light meter designed for measuring both UVA (long wave 365 nm) and UVC (short wave 254 nm) irradiance. It features an integrated SD card real-time data logger that records measurements alongside a time/date stamp directly into Excel-compatible formats without the need for additional software.

Key Technical Specifications

• Measurement Ranges: Two selectable ranges for UV: 2 mW/cm² (0.001 resolution) and 20 mW/cm² (0.01 resolution).
• Spectral Range: The sensor covers a spectrum from 240 nm to 390 nm.
• Sensor Design: Features an exclusive UV photo sensor with a metallic housing and a cosine correction filter.
• Thermometry: Includes a built-in Type K/J thermometer with automatic temperature compensation.
• Data Logging: Adjustable sampling time from 1 to 3600 seconds; supports SD cards from 1 GB to 16 GB.
• Accuracy: UV accuracy is rated at ±(4% FS + 2 dgt).
