Once the data is returned and we find it to be <br /> satisfactory, they will be released for production and sale. Here is a sample I <br /> organizations where it is currently undergoing testing: <br /> • University of Wisconsin-Madison <br /> • Tea Research Institute (Sri Lanka) <br /> • The Toro Company <br /> • USGS <br /> • Washington State University <br /> • NARC Tsukuba (Japan) <br /> • Shimane University <br /> • Iwate University <br /> • Universitat de Lleida <br /> • Oregon State University <br /> • • Saga University <br /> • University of Missouri-Columbia <br /> • University of Reading <br /> http://www.decagon.com/instruments/matricprobe.html 7/13/2005 <br />
