Recommendations for use

• Measure PAR radiation directly above the plants to ensure they receive optimal light intensity for photosynthesis.
• Use the sensor at different growth stages (seedling, vegetative growth, flowering) to adjust the lighting accordingly.
• Store the device in a dry place and replace the batteries in time for accurate measurements.
• Avoid excess or insufficient light — use the meter readings to adjust lamp height or running time.
• For mobile or temporary setups, the device is very useful for a quick check of the light profile and distribution uniformity.

VDL PAR Meter — precise PAR radiation meter

Range: 0 to 50000 lux RESOLUTION: ±1, ±10, ±100 MW700 is a portable lux meter designed to measure light in the 0 to 50000 lux range. This convenient, ergonomic lux meter is ideal for anyone seeking fast, reliable light measurements. The instrument is suitable for a wide range of applications, including hydroponics, agriculture, horticulture and environmental analysis. The light sensor is attached to a 1.3 m (4.4') cable and is suitable for checking light intensity. Average indoor lighting ranges from 100 to 1000 lux, while average outdoor sunlight is around 50000 lux. Design features Fast, easy-to-read results on a large digital LCD display Silicon photodiode sensor attached to a 4.4' cable Three resolution settings – 1, 10 and 100 Battery life of 150 hours of continuous use (battery included) with a low-battery warning.
