Secure Area



This high speed, high performance postal scale will display and transmit data, integrate with back office and POS systems and give you the flexibility you need to manage vital weight data within your operation.

The high quality Avery Weigh-Tronix Quartzell® design enables the ZP900 to accurately weigh any item, from small letters to 150 lb/80 kg parcels on a single scale.


Maximize counter space

The ZP900 is available in two main sizes: 9 in x 12 in (230 mm x 305 mm) and 12 in x 14in (305 mm x 355 mm). With counter space at a premium, the ZP900 has been specially designed with a small footprint. The ability to allow one scale to be shared between two or more operator terminals also reduces the need for counter space, while increasing customer throughput.


Display options

The ½ in / 13 mm weight display uses Improved Black Nematic (IBN) technology, which provides a high contrast, high quality green on black display. This technology provides exceptional contrast ratio and a wide viewing angle, making it easy to read in a variety of lighting conditions.



The ZP900 can communicate using a wide range of channel options such as RS232, USB or Ethernet. Ethernet connectivity is standard, enabling simple integration with software and providing a wealth offuture-proofed opportunities for the customer. It can also be used as a local or remote diagnostic port.

As well as being future-proofed, the ZP900 ensures backward compatibility with a range of standard postal protocols, such as NCI & ECR, D904 and SMA as well as older scale models such as the FX141, NCI 7600 and NCI 7800.


Third party integration

The ZP900 can also be installed flush fit into the counter or integrated into a kiosk or static dimensioning solution. By installing the weighing platter flush with the counter and suspending the weighing mechanism underneath, boxes and parcels can be moved on and off the scale with minimum effort.

With Serial, USB and Ethernet connectivity, the ZP900 has been designed for compatibility with all third party software and OPOS systems, providing a platform for new technology developments in the postal and shipping industry.


Accuracy, speed and reliability

Available in several multi-range capacities from 10 lb/6 kg up to 150 lb/80 kg, the ZP900 uses the latest digital Quartzell weight transducer technology from Avery Weigh-Tronix, to ensure a fast return to zero between readings. This offers users the speed and repetitive accuracy that can be vital in situations where there is a large through-put of packets.
