Our organization, the G.S. Gabel Corporation, Victoria BC Canada, has developed a novel, patented approach to the use of TDR (Time Domain Reflectometry). to resolve a number of problems related to the measurement of moisture content in soil and other porous media. Our system, Moisture Point, is now used in numerous countries and features the following advantages: * the unique segmented probe design provides a instantaneous profile of the soil moisture in up to five discrete increments, with minimal soil disturbance. * the higher signal discrimination of our sampling technique ensures operation in a wider range of conditions, including in conductive media: saline soil, compost, clay, where moisture measurements were until now not possible * the system can be either manually operated, or left unattended with a datalogger, and configured as a single or multi probe installation * A software allows communication with the instrument, raw data analysis, probe and soil parameters optimization. The cost for a complete system including one segmented probe is below $US 6,000. At this point we are interested in your application and we would like to be able to tell you more precisely how Moisture Point can be usefull to your research. If you have any questions or suggestions, or if you know scientists that you would like us to contact, or if you wish to receive documentation about Moisture point, you can reach us at gabel@islandnet.com Gabel Corporation. Victoria, BC, Canada. 1.604.479.6588/1.604.479.1412. Best regards, Pierre Ballester.

Pierre also had the following to say on the Virrib system:
I can eventually get you some data and test results on Virrib probes if you send me your address or fax number. However I would like to ask you if you could tell me more about the application for which you need moisture probes.in response to a request form Bill PogueFrom: Irrometer (Irrometer@aol.com) To: sowacs@aqua.ccwr.ac.za Date: Thursday, August 29, 1996 10:08 pm Subject: VIRRIB SOIL MOISTURE SENSOR Has anyone had any practical experience with this sensor technology? Pro and cons? Cost considerations? More of a research tool than for a production ag mode? Principle of operation (TDR, FDR, ETC.) ? Thanks. Correspond directly with me if you wish.
