Light Intensity Lux Meter

It is equal to one lumen per square metre.
Light intensity lux meter. To begin turn off any lighting in the room you re about to measure. Measurement range accuracy resolution and sampling rate vary from meter to meter. Key features of lux meter. From measuring the amount of light in a work space surface to ensuring emergency exits have proper illumination light measurement and analysis.
Professional light intensity lux meter that measures illumination levels in lux. How to measure light intensity using lux light meter. Eyes have different sensitivities to colours or wavelengths and perceive yellow and green light. Measure ambient light in the room.
It features direct reading in lux or fc and also displays the measured light color temperature in degrees kelvin k. The measure of the lux light meter varies depending on the light s intensity and distance. If a point source has no reflections a portion of the produced light reaches a surface. Record your measured light illuminances create locations for your points of measuring live line chart shows the actual trend of the light intensity line chart for every record in your history supports lux lx and foot.
Lx is the si derived unit of illuminance measuring luminous flux per unit area. Lux light meter for photography grow plants led photometer lighting intensity brightness measurement pocket digital photo illuminance sensor 4 3 out of 5 stars 7 18 95 18. Also light color measurement requires device with an rgb light sensor. Turn on the light meter to establish what s known as the baseline measurement.
This app requires device with a light sensor. Measuring light intensity using a lux meter. In order for this meter to be exact you need to perform calibration. In photometry this is used as a measure of the intensity as perceived by the human eye of light that hits or passes through a surface.
It is analogous to the radiometric unit watt per square metre but with the power at each wavelength weighted. Using a light lux meter is the best way to measure light intensity it gives us the ability to choose the optimal light intensity for an environment. Luminous intensity is measured in lumens per square meter lux or lx or lumens per square foot foot candles or ft c. A klux is a 1000 lux and about 1 1 klux is the minimum light requirements for any plants for at least 12 hours per day to gain any benefit from fertilization.
The lux light meter s calculation of illuminance is done by using the point source process. The light intensity is shown in lux and fc. Lux meters should fulfil specific criteria in order to be able to measure the light intensity and light conditions reliably and precisely. Lux meter is a simple light meter for measuring illuminances by using the light sensor of your device.
