NOTE: To get off this list, send email to majordomo@aqua.ccwr.ac.za with the body of the message containing the line: unsubscribe sowacs Dear Alan: Please, have a look on our web site www.paltin.com Our research, technology transfer and consultancy company, focused on real-time soil water profile and temperature dynamics, is offering the best 21st century real-time soil water content sensors, probes, monitoring and telemetry systems proved to be reliable in the U.S. and internationally. Technical descriptions and on line shopping are available. New Campbell Consulting dielectric soil moisture, temperature and conductivity sensors have been added recently. Stevens-Vitel Hydra multipurpose probes (soil moisture, temperature and conductivity) are available, too. As TDR probes, the ESI Moisture Point 29 channel multiplexer (capable of supporting 29X5 segment profiling probes) is now available. Our company is offering multiple choices between capacitance, impedance, TDR and TDT (time domain transmission) based probes, in order for you to make a technical and financial analysis. Our invitation is still on for you and your colleagues to participate at the "First international symposium on capacitance, impedance and TDT based probes-Achievements and Challenges of the 21st century" to be held in the first week of November, 2002". This week you will see at sowacs and other professional lists the first call for participation with papers, posters and exhibitions at Symposium-2002. Your timely response is greatly appreciated. Best wishes, IOAN Ioan C. Paltineanu, Ph.D. - President Paltin International Inc. 6309 Sandy St. Laurel, Maryland 20707 U.S.A.
