• +/- 4% of readings for 19,000 Lux, 1,999 FC; +/- 6% of readings +/- 10 digits for 199,999 Lux, 19,999FC
• 2~3 times sampling per second, Instantly to measure out how much luminosity intensity you're getting, No more guessing
• This light meter can measure luminance at 0.01~199,999 Lumens, (0.01~19,999 Foot Candles), Which is much wider than the others. Resolution 0.01
• The light sensor can be rotated 360º or Probe is removable for use, 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.
• The RELATIVE measuring mode will show you the difference between current / recorded data. lux meter to measure light intensity for LED grow lights,garden, plants, school, office, state, LED lights, indoor and outdoor.
