The Extech LT300 is a precise light meter for measuring illuminance levels up to 40,000 foot-candles or 400,000 lux. It is ideal for indoor light measurements as well as safety-related applications such as checking lighting in parking garages, stairwells, hallways, outdoor areas, ATM locations and other safety-critical zones.
Thanks to its high resolution of 0.01 Fc/lux and precise color and cosine correction, the LT300 delivers reliable measured values. The external light sensor on the 30.5 cm spiral cable (extendable to 61 cm) facilitates measurements in hard-to-reach places and allows flexible positioning during the measurement.
The large LCD display with analog bar graph provides a clear display of all measured values, supported by a backlight for use in dimly lit areas. Functions such as relative mode, peak hold, min/max memory and data hold make the device a versatile tool for lighting analysis.
The LT300 is supplied fully ready for use with a protective sensor cap, protective cover, 9 V battery and carrying case.
