Bakker, Gerben writes to the sowacs list: ===8<============== I am not an expert on this issue, but isn't is better to measure the water retention, because cels in crops react to the osmotic potential? Or measure the volumetric water content and at the same time the volume with an intelligent optic device. Just thinking loud. Greetings, Gerben -----Original Message----- From: Bruce -owner of sowacs [mailto:bruce@sowacs.com] Sent: dinsdag 18 november 2003 7:52 To: Bruce Metelerkamp Subject: Fwd: Re: Fwd: Soil Moisture Meters suitable for use in dried fruit? Cliff Hignett writes to the sowacs list: ===8<============== A device based on the principles of the neutron moisture meter is used routinely in minerals processing to measure water content of minerals on conveyor belts. I have also had contact with people measuring water content on dried blood with a theta probe - worth a try but remember the theta probe measure volume water content - so density of your fruit would be critical. My feeling is that some form of infra red or microwave system could be made to work. If you want to follow up get in touch privately.
