Extech EA33 Light Meter with NIST Calibration

The Extech EA33-NIST EasyView Light Meter is a compact, rugged tool built for high-intensity light measurements across a wide range of applications. Capable of measuring up to 99,990 Foot Candles or 999,900 Lux with high resolution (0.001Fc/0.01Lux), it delivers precise results in demanding lighting environments. The unit features a large LCD display and advanced illuminance functions such as candela calculations, timed hold, relative and percentage deviation readings, and a ripple function that filters out stray light interference.

This light meter includes the ability to store and recall up to 50 measurements with time or real-time stamps, enabling users to perform detailed light tracking and analysis. A built-in comparator function provides high/low alarm capabilities, while the auto power-off feature ensures energy efficiency. NIST certification guarantees its measurement accuracy, making it ideal for professional settings where calibrated results are critical.
