Product outline
F741R2 is a desktop type load cell indicator that can be used for any type of platform scale. The most important features include field operability such as a large display tube, which is easy to read even in harsh environments, and maneuverable one-touch function keys. With the counting function to display the parts quantity, the HI/LO limit comparison function conveniently used for checkers, and the multi-interval function, F741R2 is an indicator excellent in cost effectiveness.
