This meter is a precisions instrument for measuring light intensity. With 4 1/2 LCD display screen and data retention function, and the display unit can be changed between W/m2 and Btu, also has wide applications. Come on and try it, it wil not let you down.

Features:
4 1/2 LCD display screen, the maximum displayed numerical value is 19999 and the over load display is "OL".
Two units selectable: You can choose the suitable units from W/㎡ and Btu/(ft²-h）for your different needs.
With the data retention function and wide measure ranges without adjustment functions.
Wide applications: It can be used in solar radiation measurement, solar research, physical and optical experiments, meteorology, and agriculture, also be used to measure glass light intensity to verify glass properties, for example, measurement of light intensity through vehicle windows.
Small in size and easy to carry, you can take it with you to anywhere you want to use it.
Low battery alarm functions: When the battery voltage becomes too low, the low battery sign will appear on the screen, indicating that the battery needs to be replaced.
