My apologies to the list for not pasting in a link. This should take you straight to it: http://patft.uspto.gov/netacgi/nph-Parser?

It is a scale that can be left on a hive year round. They no longer manufacture it, and the patent has long since expired, I just haven't been able to find it yet. Given the price tag of wiring a single hive for weight, temperature, humidity and sound frequency, I have been designing my own set of scales to leave on my hives, as well as an apiadicator to be able to plug in to check for sound levels, thermometer and hygrometer to follow. :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
