1.1. HIGH ACCURACY: Our Lux meter ensures high accuracy with a reading deviation of only 4% for measurements up to 10,000 Lux or 1,000 FC, and 5% for readings up to 400,000 Lux or 40,000 FC. You can trust the precision of our device to provide accurate luminosity intensity measurements. 2.2. INSTANT RESPONSE: With a quick 0.4-second response time, our Lux meter near-instantaneous results. You no longer have to the luminosity intensity; simply measure and obtain the readings in seconds. 3.3. WIDE MEASUREMENT RANGE: Unlike other light meters, our Lux meter an impressive measurement range from 0.01 to 400,000 Lumens (or 0.01 to 40,000 Foot Candles). This wider range allows you to capture a broader spectrum of luminance levels, ensuring versatility in various lighting conditions. 4.4. EASY TO USE: Our Lux meter features a rotatable light sensor that can be adjusted up to 270º. This design eliminates the need to reposition the entire device when measuring luminosity intensity from different angles. Simply rotate the sensor to your desired direction and accurately read the illuminance at the front. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
