HO1

The HO1 was the first single pan balance manufactured by Oertling. It is a three knife edge design based on earlier instruments except the beam runs from front to rear in the balance case and mechanical weight loading is mounted on a carrier below the rear knife edge.It has air damping.

The balance is fitted with a Releas-O Matic device which was used on earlier two pan instruments.This device controls the speed of the fall of the beam when the balance is released. The Releas-O-Matic device consists of a carbon cylinder and piston with a two stage air valve.When the balance is released by pressing the bar at the front of the instrument the beam is lowered slowly until the centre knife comes in to contact with the centre plane,the arrestment frame then drops away quickly which allows the beam to swing without fouling.
