Advanced Visible Light SD Card Logger

Advanced Visible Light SD Card Logger

The Sper Scientific 850005 Advanced Visible Light SD Card Logger is an indispensable tool for professionals requiring precise light measurement and temperature monitoring. This sophisticated device combines the functionality of a dedicated lux/foot-candle meter with the versatility of a Type K or J thermocouple thermometer, all while offering seamless data logging to standard SD cards.

Unrivaled Light Measurement Accuracy: Experience unparalleled accuracy in any environment thanks to its advanced compensation function. This logger intelligently adjusts readings for various light sources including tungsten, fluorescent, mercury vapor, and natural daylight. This critical feature ensures consistent and reliable measurements, eliminating the common inaccuracies found in lesser devices and providing a true representation of illuminance levels (lux and foot-candles).

Effortless Data Logging and Analysis: Say goodbye to tedious manual recording. The 850005 simplifies data collection by logging measurements directly onto readily available standard SD memory cards. This offers virtually unlimited data storage – simply swap out a full card for an empty one to continue your work. A key advantage is the direct export of pre-formatted data to Excel, allowing for immediate analysis on any computer without the need for proprietary software or complex connection cables. Each recorded data set includes the precise lux or foot-candle reading, along with the exact time and date, enabling comprehensive trend analysis and reporting.

Robust Feature Set for Professional Use: Designed with the user in mind, this logger boasts a range of practical features:

• Push-button Zero Adjustment: Ensures accurate calibration before each use.
• Min/Max Hold: Instantly recalls the highest and lowest readings captured.
• Autoranging: Automatically selects the optimal measurement range for convenience.
• Auto Power Off: Conserves battery life when not in active use.
• Low Battery Indicator: Provides timely alerts for power management.
• Data Hold Function: Freezes the current reading on the display for easy viewing.
• Thermocouple Temperature Reading: Expand your monitoring capabilities with optional Type K or J probes, providing flexibility for various applications.

Durable Design and Intuitive Operation: Crafted for durability and ease of use, the unit features a rugged, well-made construction with a fast response time for dynamic environments. The large, easy-to-read backlit LCD display ensures clear visibility in all lighting conditions. For hands-free operation and enhanced stability, it includes a convenient fold-out easel back and a standard tripod mounting screw. We highly recommend utilizing a tripod for the most consistent and accurate measurements.

Ready for Immediate Deployment: The Sper Scientific 850005 comes complete in a soft carrying case, ensuring protection and portability. The package includes a high-quality, detachable color-corrected probe that strictly adheres to the C.I.E. photopic spectrum for accurate human eye response simulation. Also included are 6 AA batteries, a detailed instruction manual, and an SD card (840059) to get you started right out of the box. For continuous operation, consider the optional USB Power Cable (840058) or AC Adapter (840097).
