LightScout DLI 100 Light Meter
The LightScout DLI 100 Light Meter measures and determine the Daily Light Integral or in other words the amount of light an area or plant receives during 24 hours.
Inside and Outside Models
You can choose from a model for inside or greenhouses (ST-3405G) and a model for turf or outside plants (ST-3405T).
Both models measure using the same principle, but have slightly different scale of division on the display.
Multi Packs
When you need multiple meters, you can choose a 3-pack as it is more cost efficient.
Specifications:
- Simple, one button operation
- Meter runs for 24 hours and calculates the Daily Light Integral (DLI)
- Real-time intensity levels are shown in µmol·m-2·s-1 every 4 seconds over the course of a day
- Measures PAR light (Photosynthetically Active Radiation - 400-700nm)
- Battery included
- Water resistant

Note. It is not possible to make a direct conversion between an instantaneous light measurement and the Daily Light Integral. Also other factors like temperature have an effect on plant quality and growth. |
