Light Meter, Luxmeter Lumen Meter Handheld Light Calibrator With 270° Rotatable Detector, Measuring Ran 0.1~300,000Lux

HIGH ACCURACY+/- 4% of readings for 10000 Lux, 1000 FC; +/- 5% of readings +/- 10 digits for 400000 Lux, 40000FC 0.4 SECOND RESPONSE2~3 times sampling per second, Instantly to measure out how much luminosity intensity you're tting, No more guessing WIDE MEASURE RAN This light meter can measure luminance at 0.01~400,000 Lumens, (0.01~40,000 Foot Candles), Which is much wider than the others. Resolution 0.01 EASY TO USEThe light sensor can be rotated 270º, so you don't need to turn around the light meter to measure luminosity intensity from different angles. Just rotate the sensor, and you can still read the illuminance at front MEMORIZE THE LIGHT READINGSThis Lux Meter can help you record 33 sets of readings,Temp Testing, The RELATIVE measuring mode will show you the difference between current / recorded data.
