Sper 850032 UV Light Meter UVA/UVB: Precision, Reliability, and Versatility

The Sper 850032 UV Light Meter is an advanced and indispensable tool designed for precise and reliable measurement of UVA and UVB irradiance. Engineered to meet the rigorous demands of various professional fields, this meter ensures accurate data collection across a broad spectrum of industrial, environmental, and healthcare applications.

Unmatched Precision for Critical Applications This instrument is specifically calibrated for UVA and UVB irradiance measurements within the critical 260 nm to 390 nm wavelength range. This targeted spectral sensitivity ensures that you are measuring the most relevant portions of the UV spectrum, making it ideal for tasks such as:

• Industrial Curing: Monitoring UV lamp intensity for optimal adhesive, ink, and coating polymerization.
• Sterilization Processes: Verifying the effectiveness of UV germicidal lamps in medical and laboratory settings.
• Environmental Monitoring: Assessing solar UV radiation levels and their impact.
• Material Science: Testing UV degradation or protection properties of materials.
• Cosmetics and Skincare: Evaluating UV filter performance.

Superior Measurement Capabilities The Sper 850032 offers two versatile measurement ranges:

• 2 mW/cm²: For highly sensitive measurements with a fine resolution down to 0.001 mW/cm².
• 20 mW/cm²: For higher intensity applications, with a resolution of 0.01 mW/cm².

Both ranges boast high accuracy of ±(4% FS + 2 digits), ensuring dependable and repeatable results. The inclusion of a robust UV photo sensor with a cosine correction filter guarantees accurate readings regardless of the angle of incident UV light, a crucial feature for real-world scenarios.

Designed for Practicality and Ease of Use Featuring a large, easy-to-read LCD display (51 mm x 37 mm, 1999 counts maximum indication), the meter provides immediate and clear irradiance values. Its user-friendly design incorporates:

• Data Hold Function: Freeze current readings for convenient recording.
• Memory Recall: Easily access maximum and minimum measured values, critical for identifying peak exposures or consistent low levels.
• Manual Zero Adjustment: A push-button feature allowing for precise calibration control before measurement.
• Tripod Mount: For enhanced stability and consistently accurate readings, especially during prolonged monitoring or when precise positioning is required.

Robust Construction for Demanding Environments Compact and durable, the Sper 850032 is built to withstand challenging conditions. Its robust housing ensures longevity and reliable performance, whether in a laboratory, on a manufacturing floor, or out in the field. An auto power-off function helps conserve battery life, and the "----" over-range indication clearly alerts users to conditions exceeding the sensor's capacity.

Advanced Data Management For professional integration and comprehensive analysis, the device includes an RS232/USB computer interface. This connectivity allows for seamless data output, enabling users to:

• Log data over time for trend analysis and quality control.
• Generate detailed reports for compliance and research.
• Integrate measurements into larger data acquisition systems.
