Hey Tim I have had experiences with Pinpoint and they are not very accurate over time nor do they last long! People I have talked to seem to agree. I have not heard anything bad or good about Hanna. They are specific to scientific products so they may be up to sbuff. Good luck. My pH Meter is made by Bischof a German Company and I have had it up and going for about 8 years now. With only one probe replacement I have to say I have been very pleased with the quality. My counductivity Meter is made by Oakton and I have been very pleased with its accuracy and ease of use. Good luck Yim. My Two Cents ===== David Sanchez Orlando, FL http://www.mindspring.com/~barbax barbax@mindspring.com __________________________________________________ Do You Yahoo!?
