The MW700 is a portable lux meter designed to perform light measurements from 0 to 50000 lux. This handy and ergonomically designed lux meter is ideal for anyone looking for fast and reliable light measurements.

Range : 0 to 50000 lux
Resolution : ±1, ±10, ±100

This meter is suitable for a wide range of applications such as aquarium and aquaculture, hydroponics, agriculture, horticulture and environmental analysis. The waterproof light sensor is attached to a 1.3 m (4.4') cable and is suitable for monitoring the light intensity on the bottom of aquariums.

Average indoor lighting varies from 100 to 1000 lux and average outdoor sun shines about 50000 lux. Lux is a unit that indicates the density of light falling on a surface. The human eye is only sensitive to blue, green and red light, so when calculating the Lux incident on an object, only the light that the human eye sees is counted. When only infrared light hits an object, the Lux is counted as zero since our eyes see nothing. Mathematically, a spectral weighting function is involved with the actual illumination spectrum to calculate Lux exactly.

This is the formal definition of Lux and it makes Lux an unusual unit of measure. Still, Lux can be seen 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 is equal to 0.0929 footcandles.

Design features

• Fast, easy-to-read results with large LCD digital readout
• Waterproof silicon photodiode sensor attached to a 4.4' cable
• Three resolution settings - 1, 10 and 100 Lux
• Accuracy to ±6% of reading ±1 digit
• Lightweight and portable 150 hours of continuous battery life (battery included) with low battery warning Measure LUX on the bottom of an aquarium: place the light sensor on a stable surface in the aquarium and hold the meter at the correct distance to avoid interference or disturbance to the sensor lighting. Turn on the meter by pressing the ON/OFF button.
• Press one of the three "range" keys to select the appropriate scale based on the intensity of the light. 2000-19000 is recommended for measuring LUX in an aquarium. Wait about 1 second for the reading to stabilize.
