The Testo 540 is an innovative ambient light monitor.
Testo 540’s light sensor is adapted to the spectral
sensitivity of the eye, (it see bright light at the same
sensitivity your eye does) which makes it 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. |
