The BIRTHweigh III scale developed by PATH allows a non-literate community health worker or birth attendant to weigh a newborn using a simple handheld method.  The design of this sling-based scale uses color  to demarcate low birthweight (LBW) from normal (<2000g, 2000–2499g, and >=2500g), a critical factor in ensuring survival and proper treatment of newborns.  In addition to color, the scale uses 3  tactile system for low-light situations.   Path notes that each level of birthweigh corresponds to a specific dose of gentamicin for bacterial infection.
