    Abstract: A weight scale is made splash resistant from being splashed by liquids. Means is also disclosed for making the weight scale vapor resistant. The scale includes a housing on a column on a base and a force-to-electrical output transducer is mounted enclosed within the upper housing. A rod is enclosed within the column and is moved longitudinally therewithin by being connected to a lever system connected to the pan or platform on which the weight is received. The rod acts on the transducer and an electronic circuit provides an indication of the weight on an indicator also in the housing. Liquid splash-resistant means is positioned between the bottom of the base and the transducer within the housing for splash-resistant protection of this transducer.
