>Far better to trust the laws of physics, and go with a mechanical scale As much as I enjoy a number of electronic devices (I haven't used my slide rule in years), I also trust mechanical scales more so than cheap digital. I use my old triple beam balance all the time, including for measuring oxalic. Be sure to use plastic weigh boats (or a plastic cup) to avoid getting acid on the balance. -- Randy Oliver Grass Valley, CA www.ScientificBeekeeping.com *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
