VDL LUX METER

Description

The VDL Luxmeter is a highly accurate and easy to use light meter.

The VDL luxmeter has one of the highest levels of relative sensitivity, which gives it an extraordinary detection capacity for wavelengths from less than 500 nm to above 650 nm.

It has a large LCD screen. Although this lux meter is a highly accurate instrument, its construction of high quality materials will provide the user with many years of use.

The cable that connects the VDL luxmeter with the photo-sensor allows the user to make measurements in a more comfortable position or in the optimal position with respect to the light source. The sensor has an opaque cover that prevents the entry of dirt or scratches and that in turn allows proper calibration. Ranges: from 0 to 200,000 lux in 4 ranges.

The VDL luxmeter is a reference instrument that tells us when to change the lamps of the crop . The user must make a measurement when starting the crop, for example, 30 minutes after starting the equipment and 30 centimeters away and always in the same position and situation of the equipment. This reading will present downward differences in successive crops and the grower must change the lamp when the reading drops by 10 or 15% compared to the initial reading.

WHEN SHOULD I CHANGE THE SODIUM LAMP OF THE VDL LUXMETER?

We recommend changing the lamp when the value of the production loss is greater than the value of a new lamp, that is, around 50 euros (in the case of a 600 W lamp). Professional indoor growers and nurserymen change the lamp every time they grow. It is recommended to change the lamp every 2 or 3 crops at most.
