Cat. No. QSW-01
Multi-Mode Quantum Meter
with integral sensor

The QSW-01 quantum meter features a compact design with a state-of-the-art light sensor located on top of the meter.   The QSW-01 also features a large, stable LCD display which shows PPF units directly as µmol m-2 s-1.  Select between two preset display modes: sunlight or fluorescent light depending upon the light source you wish to measure.  Operation is simple.  Select the display mode and take your reading. 

The instructions include a list of  correction factors  to easily convert PPF from other light sources such as  incandescent, high pressure sodium or metal halide lamps.
