DESCRIPTIVE ANNEX
Characteristics of the instrument:
The ALG-H series are class I and class II, self-indicating and non-automatic weighing instruments.
The mass detection method of the ALG-H series is a tuning fork sensor.
The instruments can be switched to the unit of measurement (momme) for special
applications, e.g. trade with pearls.The symbol for the momme is mom(1 mom = 3.75 g).
