Features
• Simple, one button operation
• An affordable first step in measuring light
• Measure PAR light (Photosynthetically Active Radiation – the range between 400 and 700 nm)
• With the push of a button, the meter runs for 24 hours and calculates your Daily Light Integral (DLI)
• Real-time intensity levels are shown every 4 seconds in μmol•m-2•s-1 (or footcandles)
• Packaged in sets of 3 light meters
• 3V CR2032 Battery included – approximate battery life: 60 DLI calculations
The LightScout DLI 100 Meter is an affordable first step in measuring the light intensity levels affecting your crops. Sold in sets of three to compare light level intensities within or outside your greenhouse. With a push of a button, the DLI 100 Meter records light intensity for a 24 hour period and then calculates the Daily Light Integral (DLI). Real-time intensity levels are shown every 4 seconds in µmol m-2 s-1 (or footcandles).
Using the DLI100
Place the DLI 100 in the ground at the desired location for evaluating the amount of available sunlight. In a greenhouse insert the meter into a container of similar size (containing substrate only) to that of the crop being grown. By so doing, the meter is receiving the same amount of light at the same height as the growing crop. Ensure that the face of the unit is generally parallel to the ground.
Light Gathering Mode
To turn the DLI 100 press the power button located on the shoulder of the device. When the power is applied, the four LEDs will illuminate sequentially from bottom to top. Thereafter, one or more LEDs will flash every 4 seconds, indicating the amount of light currently being received.
The DLI 100 measures the actual light intensity every 20 seconds, then displays that value every 4 seconds until the next measurement is made.
Note: While the DLI 100 is gathering data, pressing the power button will turn off the unit (the four LEDs will illuminate sequentially from top to bottom), and the measurement process will be cancelled. Pressing the button again will start a new 24 hour measurement period.
DLI Display Mode
After 24 hours of continuous operation, the device will stop accumulating light measurements. One or more LEDs will flash every second to indicate the Daily Light Integral (DLI) for that location. The device will shut itself off after displaying the DLI value, but the DLI measurement will be retained in memory. The last DLI value computed can be retrieved from memory by pressing the power button to turn on the unit. The DLI value will flash every second for 10 seconds.
