LED Light Meter with Color Temperature Compensation, NIST

Sper Scientific LED Light Meter with Color Temperature Compensation and NIST Certificate

Unlock unparalleled accuracy in LED lighting measurement with Sper Scientific's advanced LED Light Meter. Unlike conventional light meters, which often falter when faced with the diverse color temperatures of modern LED illumination, our device stands out. It's meticulously engineered to compensate across a broad spectrum of LED color temperatures, ensuring reliable and precise readings every time.

Precision Tailored to Your Needs: Simply select from a range of common LED color temperatures – 2700K, 3000K, 3500K, 4000K, 4500K, 5000K, or 6500K – and the meter's internal calibration intelligently adjusts. This intelligent compensation guarantees equally accurate results, whether you're measuring warm white or cool daylight LEDs. For comprehensive versatility, it also includes a dedicated mode for traditional incandescent lighting.

Intuitive Readouts & Robust Features: Readings are clearly displayed in either Lux or Foot Candles on a large, easy-to-read screen that also indicates low battery status. Beyond basic illuminance, this meter offers a more thorough analysis by reading luminous intensity, precisely correcting for the distance from the light source. Its cosine-corrected silicon sensor strictly adheres to the C.I.E. photopic spectrum, ensuring professional-grade accuracy.

The meter boasts a suite of convenient features including auto-ranging for effortless operation, zero adjustment for baseline calibration, and Min/Max/Average functions to capture fluctuations and trends. Data hold allows you to temporarily freeze readings, while the ability to store up to 99 manual data points facilitates detailed record-keeping and analysis.

Ready for Immediate Use: Each unit comes complete with clear, user-friendly instructions, a standard tripod screw for stable measurements (we highly recommend using a tripod for optimal accuracy), a 9V battery, a protective sensor cover, and a durable hard protective carrying case to safeguard your investment.

• Lightweight & Portable: Designed for field use and easy transport.
• 5-Year Warranty: Assurance of quality and lasting performance.

NIST Traceable Calibration for Ultimate Confidence: Your Sper Scientific LED Light Meter is supplied with a Certificate of Compliance, guaranteeing its precision. Each meter undergoes rigorous testing in our in-house laboratory, confirming it meets or exceeds all published specifications. All certifications are performed using instruments and standards directly traceable to the National Institute of Standards and Technology (NIST), providing you with verifiable accuracy and peace of mind.
