    Testo 540 Pocket Lux Meter

    The Testo 540 Pocket Lux Meter measures artificial and natural light from 0 to 99999 Lux, and has an accuracy of ±3 Lux or 3% and a resolution of 1 to 10 Lux. The measurement range is based on the spectral sensitivity of the human eye which makes it ideal for measuring light levels in workplaces, shops and offices.

    The compact dimensions, supplied belt clip and low weight of the Testo 540 make it very easy to carry around and use so it is great for performing spot checks. Readings are shown on the backlit LCD screen which has a min/max feature and data hold. Operation is undertaken using just three buttons and the light meter boasts a 200-hour battery life. A protective cap, batteries and a calibration protocol are supplied as standard and there is a two-year warranty.
