Extech EA33 Easy View Light Meter with Memory
This compact and ruggedly designed meter has a wide measurement range to 99,990 Foot Candles in five ranges and 999,990 Lux in five ranges with 0.001 Fc/0.01 Lux resolution. Comes with built-in stand, light sensor and protective cover with 36-inch (0.9-meter) coiled cable, protective holster, six AAA batteries, carrying case, and user manual. Model EA33-NIST is also available with a NIST traceable Certificate of Calibration.
Store and Recall up to 50 measurements with relative or real time clock stamp, Luminous intensity (candela) calculation, a ripple function that excludes stray light from the primary light source measurement, multipoint average function, timed hold, relative measurement in absolute value or percent deviation, comparator function with high/low alarms, and auto power off with disable.
A light meter measures the amount of visible light, also known as illumination, in a given area. For many meter brands, including Extech, illumination is expressed in units of measure called Lux (for metric) and foot-candles (used in the US). To use an Extech light meter, the sensor is placed on a tabletop or other surface in the area to be measured and the light level reading is indicated on the meter's display.
The Extech EasyView Wide-Range Light Meter measures up to 40,000 foot-candles in four ranges and 400,000 lux in five ranges with ±3 percent accuracy — ideal for outdoor use. It features a compact and rugged design with a large display and analog bargraph to view trends. Peak mode captures short light pulses to 100µs. Relative function zeroes the sensor or can be used to display the difference from a reference value. Additional functions include data hold, min/max, and auto power off. Comes complete with built-in stand, remote sensor with protective cover and 39-inch (1-meter) coiled cable, protective rubber holster, six AAA batteries, and carrying case. Model EA30-NIST is also available with a NIST traceable Certificate of Calibration.
