The Electronic Measuring Rod is the easy, convenient, electronic measuring device that proves its worth in many ways, but most importantly by preventing human error. A built-in electronic memory will store 10 measurements, and an optional push-in memory module lets you store up to 511 measurements. Simply access your stored measurements and you have prevented the "double work" of writing down your figures, thus avoiding costly translation errors. Two sizes are available with a retracted length as short as 28" (711 mm), and a full extension length as long as 197" (5.00 m). Ask our Technical Sales Department about an optional interface to transfer stored data to an IBM compatible PC.
