Description The Yokogawa 51001 LUX Meter has a wide measurement range, high accuracy and spectral response characteristics for visible range It also has a very good oblique incident light characteristics and a recorder output/digital output. If you need to accurately measure LED lighting this is the lux meter for you. Specifications: Phototelectric element : Silicon photodiode Measuring Range : 0.0 to 99.9/999/9,990/99,900/999,000 lux Response Time : 2 sec (auto rang) ; 2 sec (manual range) Accuracy : ±4% rdg ±1 dgt Why buy the Yokogawa 51001 or 51002 lux meter over a lower cost meter? The Yokogawa meters and as a rule most of the Japanese made lux meters use Japanese light sensors that are far superior to the one in the Chinese made meters. These inferior sensors can still read reasonably accurately when calibrated and some clever electronics takes into account what colour the light source is that is being measured. For instance, if we are measuring sunlight with a Yokogawa & a Chinese meter, I would expect both to correctly read similar light levels let’s say we have a reading of 800 lux. If we then move inside where a metal halide lamp is illuminating an area the Chinese meter may read 500 lux & the Yokogawa 409 lux - which is correct? What we are seeing is the results of a user not telling the meter what colour the light source is, if you know the colour and your meter has a setting for that light source the meter should be able to calibrate out these and they will both read 400 lux. From experience even if you chose the wrong light source with the opposite characteristics of the light you are measuring the most the Yokogawa's measurement will be out is 3% - on a lower cost meter it will at least 20% to 25% out. If you have an application where there is a mixture of light e.g. sunlight, fluorescent lighting and LED lighting the only a meter that uses high quality Japanese made sensors will accurately measure the lighting levels.
