The handy, small and easy to operate Testo 540 Lux meter measures light intensity to address comfort and fatigue concerns which affect productivity and safety. The 540’s sensor is designed to mimic the spectral sensitivity of the eye. This makes the Testo 540 ideally suited to the measurement of light intensity at workplace, stadiums, auditoriums, warehouses or any where people work. The hold-function allows the comfortable readout of the measurement values. Max. and Min. values can be displayed at the press of a button. The clip-on protective cap, wrist strap and belt holder ensure safekeeping of the instrument.
