Overview
Extech 407026 Heavy Duty Light meter with four lighting types Tungsten/Daylight, Fluorescent, Sodium, and Mercury
The Extech 407026 Heavy Duty Light Meter is a compact and rugged light intensity meter that measures light level (illuminance) in three ranges: 2000, 20,000 or 50,000Lux or foot-candles. A large LCD display allows the user to read and interpret data right on the meter, while the Data Hold function allows for easy note-taking.
The digital light meter features a built-in RS-232 interface with optional data acquisition software and data logger. Measurements are simultaneously displayed in Lux and Foot-candles, and the meter provides cosine- and color-corrected measurements.
