H series - Issue 3
Digital Hook & Point Gauges H1-7/H1-8


ORDERING SPECIFICATION

A direct indicating gauge which eliminates observation errors due to vernier and scale reading. It can be set to zero anywhere in the operating range to permit easy relative level checking. The liquid crystal display is easy to read and has a resolution of ±0.01mm. A push button gives immediate change to inches from millimetres if required. A quick-release mechanism permits rapid changes of position.

Description

A mounting plate is clamped to a suitable support structure and a flat vertical shaft retained by the gauging unit is free to slide up and down over the water surface.

A steel point or hook is attached to the bottom end of the shaft and is used to locate the water surface.

The gauging unit consists of a liquid crystal electronic display which indicates the movements of the shaft.

A quick-release mechanism permits large changes to be rapidly accommodated, and a screw adjustment is provided for accurate final positioning.

A push button sets the display to zero at any position, so that relative movements compared with a datum can be easily measured.

This gauge is easy to use and minimises potential errors resulting from reading vernier scales.
