Designed for demanding industrial, environmental, and laboratory applications, this instrument integrates advanced sensor technology, a user-friendly interface, and comprehensive data logging capabilities to meet the highest professional standards. It also comes with a NIST Traceable Certificate of Calibration, ensuring its measurements are accurate and reliable from the moment you receive it.

Key Features and Benefits

Ultimate Precision and Full-Spectrum Versatility

• Professional UVA/UVB & UVC Measurement: This meter accurately measures UVA/UVB irradiance from 260 nm to 390 nm and UVC irradiance from 200 nm to 280 nm. Its high reliability makes it ideal for safety assessments, compliance checks, and scientific research. The exclusive photo sensors with cosine correction filters ensure accurate readings even when the light source is not directly perpendicular to the sensor.
• Dual Measurement Ranges: Choose between two measurement ranges—2 mW/cm² and 20 mW/cm²—to get the best resolution and accuracy for your specific application, whether you're measuring low-intensity environmental UV or high-intensity industrial sources.

Integrated Thermocouple Thermometer

• This device isn't just a UV meter; it also includes built-in Type K and Type J thermocouple functionality. Measure temperatures from -50℃ to 1300℃ (Type K) or -50℃ to 1200℃ (Type J), allowing you to simultaneously monitor UV levels and temperature—a critical feature for many industrial and research processes.

Advanced Real-Time Data Logging

• Integrated SD Card Data Logger: Effortlessly record measurements with a time-stamp (year, month, date, hour, minute, second) directly onto a standard SD memory card (up to 16GB). This eliminates the need for specialized software—simply transfer the SD card to a computer and open the data directly in Excel for seamless analysis, graphing, and reporting.
• Flexible Logging Options: Set the meter for automatic logging at intervals from 1 to 3600 seconds for continuous monitoring, or use the manual logging function to record up to 99 specific data points with the push of a button.

Designed for the User

• Large Backlit LCD: The clear 52 mm x 38 mm screen features a green backlight (with an on/off option), ensuring readability in any lighting condition, from dark labs to bright outdoor environments.
• Separate UVA and UVC Probes: The meter comes with two separate, detachable probes, allowing you to position the sensor in the optimal location for precise, targeted measurements without moving the main unit.
• Simple Zero Calibration: A dedicated push-button allows for quick and easy zero adjustment, ensuring your measurements remain accurate over time.

Robust Build and Seamless Connectivity

• Tripod Mount: A standard tripod mount is built into the housing, enabling stable, hands-free operation for consistent and repeatable readings during prolonged measurements.
• RS232/USB Interface: Connect the meter to a computer via the optional RS232 or USB cable for real-time data streaming and integration with other systems, facilitating advanced data management and reporting.

Enhanced Applications

The Sper 850031C UV Light Meter is an essential tool for a wide range of professional fields:

• Environmental Monitoring: Measure solar UVA and UVB irradiance for environmental studies, public health warnings, and material degradation analysis.
• Industrial Safety & Hygiene: Ensure workplace safety by monitoring UV exposure from welding, curing, and other industrial processes to comply with OSHA and ACGIH standards.
• UV Sterilization & Disinfection: Validate the output of UVC germicidal lamps used in healthcare, water treatment facilities, and HVAC systems to ensure effective sterilization.
• Laboratory & Research: Accurately track UV levels in photochemistry, photobiology, and other scientific experiments to ensure precision and control.
• Manufacturing Quality Control: Assess the performance and consistency of UV lamps, LEDs, and other UV-emitting equipment used in curing, printing, and electronics manufacturing.
