Test Instrumentation

The Trimble® GreenSeeker handheld crop sensor

is an affordable, easy-to-use measurement device

used to assess the health—or vigor—of a crop in order

to make informed nutrient management decisions

on your farm.

Use the GreenSeeker handheld to instantly

take a reading of your crop’s health. Simply

aim the sensor on the underside of the device

at a crop 24 to 48 inches (60 – 120 cm) away

and pull the trigger to get a reading

Readings can be used to make non‑subjective decisions

 regarding the amount of fertilizer to be applied to your crop,

resulting in more efficient use of fertilizer—benefiting your

bottom line as well as the environment.

 

 Collecting data is easier than ever with Bluetooth® connectivity

built into the sensor. With a linked mobile device running a

compatible app (such as GreenSeeker BT Logger for Android™

mobile devices), NDVI values can be recorded for future analysis.
