Product Overview
Built for the rigors of everyday commerce, the Weicomp Trade Approved range features a durable painted steel chassis topped with a high-grade AISI 304 stainless steel platform. Unlike standard internal-use scales, these models are specifically calibrated and sealed to maintain legal-for-trade tolerances in environments such as manufacturing hubs, packing stations, and goods-out departments.
While the platform is engineered for stability in dry industrial settings, the choice of indicator allows you to move from straightforward commercial weighing to advanced data handling and system integration.

Frequently Asked Questions
What does ECEM stand for?
ECEM stands for EC Type Approval for a Mass Receptor. It is the certification that allows a scale to be used legally for trade. In practice, you will see a “Green M” sticker on the scale signifying this approval.
Is a Trade Approved scale required for my business?
If you use the weight reading to determine a price, a fine, or a fee, UK/EU law requires a Trade Approved (M-Class/ECEM) scale. This model fulfils that legal requirement.
Can I use this in wet environments?
This base model is intended for dry industrial settings. For washdown areas or high-moisture trade applications, the Weicomp SS (Stainless Steel) model is the appropriate choice.
