The history of analytical lab balance dates back to 1945 when Mettler Toledo company founder Erhard Mettler introduced the first Single-pan analytical balance. Large-scale production of Toledo weights began in 1946. Nearly three decades later, in 1971, the first nanogram balance was introduced.
The first fully electronic precision balance, PT1200 scale, appeared on the market in 1973. A new force restoration technology was introduced in 1989. It eliminated many hand assembly steps, assured manufacturing quality control and, ultimately, reduced cost. Soon after, in 1993, the new Mettler Toledo electronic microbalance with a 51 million point resolution was introduced.
The first ultra-microbalance with a weighing capacity appeared in 1996 and the first monolithic weigh cell technology was introduced in 1997. Himadzu Windows Direct communication function introduced many new useful mechanisms in lab scales such as: record weight or computed values generated by the balances. The latest innovations include: adding a color touch screen, Bluetooth connectivity in 2005, 61 million digit resolution in 2009 by Mettler Toledo XP6U.
