WINNING FEATURES

• Each sensor is automatically calibrated when the soil is at Full Point by simply pushing the RED button. SIMPLY AMAZING!
• Reads the soil moisture within seconds at each sensor depth.
• Reads soil moisture in PERCENTAGE
• Soil FULL point is 100%
• The bottom end of the Readily Available Water is approx 55%
• Records data and calibration from 99 different sites and stores 81 profiles per site.
• No computer required, but a computer can be used if you want to graph or print data.
• Because the Readout unit simultaneously displays the actual percentage of soil moisture from the 4 sensors, you can tell IMMEDIATELY if you need to irrigate.
• Multiple access tubes can be installed – then the sensor string is simply dropped into the access tube.
• Suitable for all soil types from very light sand up to heavy clay.
• Suits all irrigated crops, including pasture, vines, trees and vegetables.
• The sensor string can be placed in existing Micro-Gopher ™ access tubes.
• Optional continuous timed recording is available with our low cost Odyssey recorder (NZ$99.50 ex GST), which stores 64,000 soil moisture readings.

CALIBRATION – SIMPLY FANTASTIC

The calibration of the GreenLight-RedLight ™ is so simple that you do not have to be a soil scientist or even understand the texture or name of your soil or the Field Capacity of your soil!

You can almost close your eyes and push the RED button on the Readout unit and the system will automatically calibrate each sensor for the site that you are calibrating and automatically save this calibration data in the Readout unit’s memory.

The new method of calibration and measurement allows you to know, without guessing, exactly when the soil moisture has dropped below the point when your plants can readily extract water from the soil.

You can calibrate up to 99 sites and save up to 81 soil moisture profile measurements for each site.

When the soil moisture gets down to 55% it is time to irrigate.
