TCM 500 NDVI Turf Color Meter
You are measuring the quality of your grass not by guessing based on eyesight, but by the reflectance of the grass itseld, giving you a much more reliable and less debatable or inconsistent conclusions.
The reflectance value based on NDVI technology gives a valuable reading on which your grass management decisions can be based on.Healthy grass refelcts differently than less healthy grass.
Characteristics
- Measures reflected light from approximately 7.6 cm diameter section of turfgrass
- Uses an internal light source to negate the effect of sunny versus cloudy conditions
- Measures reflectance in the red (660 nm) and near infrared (850 nm) spectral bands
- Displays result as NDVI, percent reflectance, or as a user-adjustable grass index from 1 to 9
- Connects to any GPS receiver that has a serial output option*
- Equipped with internal data logger and RS-232 port
- Configure and download meter with FieldScout® software and USB-to-3.5mm-Stereo-Plug Adapther (Item 3661U.(included)**
- Compatible with SpecConnect
- Includes hard carrying case, batteries, and TCM 500 T-Handle (item 2975H)
* GPS interface requires two cables. The GPS/DGPS cable (item 2950CV5) is available from Spectrum.
A PC serial interface cable supplied by the manufacturer of the GPS receiver is also required.
** PC cable connects to a computer USB port.
