Light Meter Lux, NIST Certificate of Calibration

Sper Scientific 840006C Professional Light Meter Lux with Optional NIST Certificate of Calibration

Experience unparalleled accuracy and reliability in light level measurement with the Sper Scientific 840006C Light Meter. Engineered for professionals, this advanced lux meter delivers fast, stable, and highly accurate responses, making it an essential tool for photographers, architects, industrial safety officers, horticulturalists, and anyone requiring precise light assessment.

Key Features for Professional Performance:

• Exceptional Readability: Measurements are clearly displayed on an extra-large LCD (⅞" high, 22 mm). This intuitive screen also provides critical indicators for low battery status and over-range readings, ensuring you're always aware of your meter's condition and data integrity.
• Precision Light Sensor: Equipped with a sophisticated color and cosine-corrected light sensor that perfectly matches the C.I.E. photopic spectrum. This ensures that the meter's readings accurately reflect how the human eye perceives brightness, regardless of the light source's angle or color temperature. Crucially, it provides accurate measurements for modern LED lighting, unlike many older meters.
• Enhanced Accuracy Control: Features an external zero adjustment function, allowing you to fine-tune the meter for consistent and precise readings in varying environments.
• Data Hold Function: Capture and record measurements easily, even in awkward or difficult-to-reach locations, with the convenient hold function that freezes the current reading on the display.
• Versatile Positioning: Designed with an integrated easel back stand for hands-free operation on flat surfaces and a tripod mounting screw for secure, stable readings, especially when long-term monitoring or precise placement is required. For the most stable and accurate results, tripod use is highly recommended.

Comprehensive Package, Ready for Action:

The Sper Scientific 840006C comes complete with everything you need to get started. Each unit includes a durable soft padded carrying case with a shoulder strap for easy transport, a detailed instruction manual, a detachable sensor with a protective cover, and a 9V battery.

NIST Traceable Calibration for Assured Quality:

For applications demanding the highest level of metrological traceability, a Certificate of Calibration is available at an additional cost. This Certificate of Compliance guarantees that your meter has been rigorously tested in our in-house laboratory, confirming it meets or exceeds all published specifications. All certifications are performed using instrumentation and standards directly traceable to the National Institute of Standards and Technology (NIST), providing absolute confidence in your measurements.
