Testo 540 PocketPro Light Intensity Meter

The sensor on the Testo 540 is adapted to the spectral sensitivity of the eye, (it see bright light just like your eye does), so it's ideal for addressing comfort and fatigue concerns that affect productivity and employee safety. The Hold function lets you read measurement values easily, and min/max values are available at the touch of a button.
