The Triplett Model LT68 Light Meter/Datalogger measures light intensity (up to 40k Foot candles/400k Lux) and verify OSHA safety requirements from fluorescent， metal halide， high‐ pressure sodium， and incandescent sources found in factories， parking lots， schools， offices， transportation lines， warehouses， hospitals， schools， and many other environments. The Datalogger automatically stores up to 16，000 readings or you can manually store/recall up to 99 readings. It features a large backlit LCD display with 40-segment bar graph， silicon photodiode sensor with spectral response filter， Peak mode (10 mS) captures highest reading， Relative mode indicates change in light levels， Min/Maxfunction recalls highest and lowest readings， Data Hold freezes the reading on the display for easy viewing， low battery indicator， and Auto power off with disable. Includes light sensor with 3 ft. (1 m) cable and protective cover， USB cable， hard carrying case， 9-Volt battery and Certificate of Traceability to NIST. 1-year warranty.
