The County of San  Luis Obispo Department of Agriculture/Weights and Measures' Weighmaster Enforcement Program seeks to provide customer confidence when buying or selling bulk products based on quantities represented on a Weighmaster certificate by ensuring uniformity, fairness and honest competition in the marketplace

A Weighmaster certificate is always needed when both parties are not present and commodity is bought or sold by count or measure.
