1. MW700 SM700 Entry level inexpensive LUX Portable Meters for fast and reliable results MW700 and SM700 are portable Lux meters designed to perform light measurements MW700 with Faster Micro Processor has a smaller ergonomic and lighter case design Other features include 100 larger and easier to read LED Display and long battery life These handy and ergonomically designed portable meters are ideal for anyone working on a low budget and still requires fast and reliable measurements These portable meters are suitable for a wide range of applications such as Educational Agriculture and Horticulture as well as water and environmental analysis Both models are supplied with a light sensor connected to the meter that measures from 0 to 50000 Lux Average indoor lighting ranges from 100 to 1000 Lux and average outdoor sun lights about 50000 Lux Lux is a unit that indicates the density of light that falls on a surface Lux 2000 19999 x10 Lux 0 1999 Xi The light is necessary for the development of the plants In fact it is necessary a sufficient contribution of light in order to favor the photosynthesis and the closing of the plants The supplement of light by means of lamps electrical workers is the method simpler and economic in order to bring the necessary light to the plants The human eye is sensitive only to blue green and red light so in calculating the Lux falling on an object o2. nly the light that the human eye sees is counted When only infrared light falls on an object the Lux is counted as zero since our eyes see nothing Mathematically a spectral weighting function becomes convolved with the actual illu mination spectrum to calculate Lux exactly MW 700 Portable Lux Meter This is the formal defini tion of Lux and it makes Lux an unusual unit of measure MW700 Still Lux can be thought of as a way of measuring light in terms of what our eyes perceive The metric unit of measure for luminance of a surface One Lux is equal to one Lumen per square meter One Lux equals 0 0929 footcandles Specifications MW700 and SM700 Range 0 000 to 1999 Lux 2000 to 19999 Lux 20000 to 50000 Lux Range setting manual through key buttons Resolution 1 Lux Light Sensor 10 Lux l 100 Lux MW700 and SM700 are provided with a light sensor connected to the meter through Accuracy 6 of reading 1 digit a coaxial cable Peak Wave Length 560 nm Sensor Type silicon photodiode Sensor Sensitivity 100 scotopic Lux Sensor Stability 2 change per year in the first two years Environment 0 to 50 C 32 to 122 F max RH 95 Lux Battery Type 1 x 9V IEC 6LR61 alkaline 0 Battery Life approximately 150 hours of continuous use 1 999 Auto off after about 5 minutes of non use X1 Weight approximately 270 g meter with sensor Range keys Press one of the three Range keys to select the p
