UV Light Meter UVA/UVB, NIST Certificate of Calibration

Sper 850032C UV Light Meter (UVA/UVB) with NIST Traceable Certificate

The Sper 850032C UV Light Meter is a professional-grade instrument engineered for the precise and reliable measurement of UVA and UVB irradiance. Designed to meet the stringent demands of scientific, industrial, and healthcare sectors, this meter provides accurate, repeatable data collection across a wide range of critical applications. It is an indispensable tool for professionals who require quantifiable verification of UV light intensity and exposure.

Unmatched Precision for Critical Applications

This instrument delivers exceptional accuracy by targeting the most impactful part of the UV spectrum. It is specifically calibrated for UVA and UVB measurements within the 260 nm to 390 nm wavelength range. This focused spectral sensitivity ensures you are measuring the specific wavelengths responsible for curing, sterilization, and material degradation, making it ideal for tasks such as:

• Industrial Curing: Monitor and verify the intensity of UV lamps to ensure optimal polymerization of adhesives, inks, coatings, and resins. Consistent curing quality depends on precise UV exposure.
• Sterilization & Disinfection: Validate the effectiveness of UV germicidal irradiation (UVGI) lamps in medical facilities, laboratories, and water treatment plants. Ensure that surfaces and air are receiving the necessary dose for effective sterilization.
• Environmental Monitoring: Accurately assess solar UV radiation levels to study their environmental impact and ensure public safety.
• Material Science: Test the UV degradation, stability, and protection properties of plastics, textiles, and other materials to predict their lifespan and performance under sun exposure.
• Cosmetics & Skincare: Evaluate the performance of UV filters and sunscreens in protecting against harmful UVA and UVB rays.

Superior Measurement Capabilities & Accuracy

The Sper 850032C is equipped with two versatile measurement ranges to handle both low and high-intensity applications:

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

Both ranges deliver high accuracy of ±(4% FS + 2 digits), guaranteeing dependable and repeatable results you can trust. The meter includes a robust, detachable UV photo sensor featuring a cosine correction filter. This advanced feature ensures accurate readings regardless of the angle of incident light, correcting for measurement errors that occur when light hits the sensor from an angle—a crucial feature for real-world field and lab scenarios.

Designed for Practicality and Ease of Use

Featuring a large, high-contrast LCD display (51 mm x 37 mm, 1999 counts), the meter provides immediate, clear irradiance values. Its user-friendly interface incorporates essential functions for efficient workflow:

• Data Hold Function: Instantly freeze the current reading on the display for convenient recording and note-taking.
• Memory Recall: Easily access and display the maximum and minimum measured values from a session, critical for identifying peak exposures or detecting performance drops.
• Manual Zero Adjustment: A simple push-button feature allows for precise calibration and nulling before taking a measurement, ensuring the highest level of accuracy.
• Tripod Mount: A built-in mount provides stability for hands-free, consistently accurate readings, especially during prolonged monitoring or when precise sensor positioning is required.

Robust Construction for Demanding Environments

Compact yet durable, the Sper 850032C is built to withstand the challenges of daily use in laboratories, on manufacturing floors, and in the field. Its rugged housing ensures longevity and reliable performance. To extend battery life, an auto power-off function activates after a period of inactivity. The meter also features a clear "----" over-range indication to alert users when the UV intensity exceeds the sensor's capacity.

Advanced Data Management and Connectivity

For seamless professional integration and comprehensive analysis, the device includes an RS232/USB computer interface (cables and software optional). This connectivity allows you to:

• Stream and log data in real-time for trend analysis, process validation, and quality control.
• Generate detailed reports for compliance, research, and documentation purposes.
• Integrate the meter’s measurements into larger data acquisition systems for automated monitoring.
