This digital lux meter measures ambient light levels from 0 up to a very bright 200,000 lux across four auto-scaling ranges, so it handles everything from dim storage rooms to direct sunlight. It also reads ambient temperature at the same time, holds up to 1,000 logged readings, and includes Bluetooth for wirelessly pulling data to a phone or PC. A backlit display with max/min/hold functions makes it easy to use on site for lighting audits, workplace safety checks, or photography setup.
