Ohaus Dial-O-Gram balance is firm favourites in schools. It offers high precision and remarkable value. The three-point base, self aligning bearings, and beam design eliminate the need for level adjustment. Zeroing is quickly achieved with a counterbalancing knob at the end of the beam. The Dial-O-Gram 310 uses a vernier dial in place of two beams making it a great time saver in routine use.
