The 7840 durable 18” x 24” Bench Scale provides a fast, accurate weight reading ideal for accommodating heavy, oversize parcels or containers found in busy post, mail and shipping rooms.

Designed with a hard wearing stainless steel weight platter and a rugged powder coated carbon steel base housing that helps to fully protect the centrally mounted aluminum analog load cell from damage.

Supplied with a built-in flush fitting, six digit ½” high LCD display that is mounted centrally in the front face of the base.

An optional second remote display can be plugged in to give a customer facing weight reading.

A range of emulation protocols are available within the scale to allow you to quickly select the correct compatible communication protocol to interface with a wide range of third party post mail & shipping software programs or host devices. This will be communicated through either a serial RS232, USB (HID) or USB (VCP) port found on the rear of the base.
