Compare the Mettler Toledo BC6L to the Arlyn Scales 620F

The Mettler Toledo BC6L is designed for affordability; although it is discontinued, the models remain reliable. Adaptable to multiple languages, including English, Spanish, French, German, Italian, and Chinese, the scale comes with an AC adapter as a power source and is legal for trade use on shipping parcels around the globe. The BC6L was replaced by the BC60 which we compare here.

The Arlyn 620F offers the same weighing features as the BC6l but with many communication options not available on Mettler, including Ethernet, WiFi and Modbus. Arlyn Scales also offers optional control functions to operate valves, motors, feeders, etc. at a much lower cost.
