The Torbal Model DRX-3 meets or exceeds all the specifications and tolerances for a Class III prescription balance as defined in NBS Handbook 44, DRX-3.
Torsiona Bands - A cobalt, chromium, nickel alloy with constant torsional properties over a wide temperature range. This alloy also offers extra strength and corrosion resistance
Deep Plexiglass Lid - Extra height permits weighing with the lid down. Plexiglass offers strength with good visibility of pan and index.
Stainless Steel Pans - Highly polished and corrosion resistant.
Sealed Case - One piece metal case has overlapping plate glass top. Complete protection against dust and chemical seepage.
Leveling Screws - Non-binding; under the case, so chemicals cannot drop into the threads and cause corrosion.
Magnetic Damping - Speeds up weighing by eliminating unnecessary swings of the pointer.
Spirit Level - Insures level of balance from front to rear.
