Brecknell PS150 Slimline (150 lb)
For heavy, bulky boxes, the PS150 Slimline's movable indicator solves the hidden-display problem, and Brecknell documents a proper calibration procedure. Steps are 0.1 lb, so it's for boxes, not envelopes. We mapped the Amazon listing with medium confidence because its title omits the model code.
Mapped from a Brecknell “Slim” 150 lb listing without a model code in the title (medium confidence).
