About This Product
Moving the sensor step by step away from a lamp and logging the lux values lets students plot how illuminance falls with distance and test the inverse square law. The same meter can compare bulbs, check classroom lighting or show the effect of angle and shading on the light a surface receives.
Frequently Asked Questions
How is a reading taken with the Digital Luxmeter?
Switch it on, point the sensor directly at the light source in the area to be measured, wait for the value to settle and record the lux reading.
