Radwag Checkweighers – Automated In-Line Weight Verification for Production Lines
Radwag checkweighers are automated in-line weighing systems designed to verify that every product on a production or packaging line meets its specified weight tolerance — rejecting underweight and overweight products automatically without interrupting line flow. Manufactured in Poland by Radwag — one of Europe’s leading precision weighing instrument manufacturers — their checkweigher range combines high-speed conveyor weighing with advanced statistical process control (SPC), automatic rejection, and comprehensive data logging to deliver 100% weight inspection at full production line speed.
Used across food and beverage production, pharmaceutical manufacturing, cosmetics, and industrial packaging, Radwag checkweighers are an essential quality control tool for manufacturers who need to comply with average weight regulations, minimise product giveaway from systematic overfilling, and protect their brand from weight-related complaints and regulatory penalties. Unlike manual spot-checking, a Radwag checkweigher inspects every product, providing real-time weight data and automatic rejection of non-conforming items via integrated reject mechanisms — air blast, pusher arm, or diverter gate depending on the application. Touchscreen HMI with product recipe storage enables fast changeover between product lines, and connectivity options including Ethernet and OPC-UA support integration with MES, ERP, and quality management systems.

Frequently Asked Questions
What regulations do Radwag checkweighers help comply with?
In the UK, packaged goods sold by weight must comply with the Weights and Measures (Packaged Goods) Regulations 2006, which implement the EU Average Weight System (e-mark). These regulations require that the average weight of a batch meets the declared weight, with defined limits on the proportion of underweight packs. A checkweigher provides the 100% inspection and SPC data needed to demonstrate compliance and identify process drift before it results in a regulatory breach.
What reject mechanisms are available on Radwag checkweighers?
Radwag checkweighers are available with a range of reject mechanisms depending on the product type and line layout: air blast rejection (for lightweight products), pusher arm rejection (for stable, rigid products), and diverter gate rejection (for fragile or irregular products). The appropriate reject mechanism is specified at the time of order based on your product and line configuration.
Can Radwag checkweighers integrate with our production management systems?
Yes. Radwag checkweighers include Ethernet and OPC-UA connectivity for integration with MES, ERP, and quality management systems. Real-time SPC data, batch reports, and reject counts can be transferred automatically for production monitoring and compliance documentation. Contact our team for integration advice specific to your systems.
What line speeds can Radwag checkweighers handle?
Line speed capability varies by model and product type. Contact our technical team with your product dimensions, weight range, and required throughput (products per minute) and we will specify the correct checkweigher model and conveyor configuration for your application.
Are Radwag checkweighers suitable for pharmaceutical environments?
Yes. Radwag checkweighers are available in GMP-compliant configurations with hygienic stainless steel construction, IP65+ protection, audit trail, user management, and 21 CFR Part 11 compliant data integrity features for regulated pharmaceutical production environments. Contact our team for guidance on the appropriate configuration for your regulatory requirements.
