ZM301 Series


Avery Weigh-Tronix ZM301 is an everyday indicator for common industrial weighing applications. This high performance, multi-function indicator will analyze, store, display and transmit data, providing you with greater visibility of weighing performance.

Hi-vis display to improve productivity

The ZM301 indicator features the latest technological advancement for highly visible displays. The high contrast, nine segment IBN display technology provides excellent color contrast and enhanced viewing angles, reducing operator error and improving productivity.

Adaptable for a variety of industrial environments

The ZM301 captures values at an astounding rate of 80 times per second and is available in a variety of enclosures to suit your operating environment:

  • Protective aluminum enclosure for office environments
  • A  robust IP69K certified stainless steel enclosure for harsh indoor or outdoor use,
  • or a stainless steel panel mount design for control room applications.

Multi-connectivity with back-office systems

The ZM301 offers multi-connectivity, with Ethernet, RS232 and a USB Host port as standard and Analog output, USB device, Current Loop, RS485/RS422 and Wireless options available.

Available Models

Harmonizer™ adjustable filtering system

The fully adjustable Harmonizer™ filtering system, which is present on all ZM300 series models, corrects environmental noise and vibration. It offers three types of application-specific filtering: multiple levels of filtering for vibration frequency, adjustment for amplitude, and finally a selectable “threshold,” or a level of weight change at which the dampening is disabled. This speeds up the weighing process, quickly identifying any weight changes that exceed the selected threshold value.

Remote operation

ZM300 series indicators can be used as remote displays, enabling easy and convenient viewing of weight information where you need it. Remote push buttons or foot controls can be attached to all the ZM300 series indicators, improving productivity by enabling operators to activate the indicator remotely in order to perform Zero, Print, Tare, Units, or F1 functions.

IP69K Certification

Amongst the range of enclosures available, the laboratory certified IP69K stainless steel enclosure offers complete resistance to dust and water ingress. This certification offers users reassurance that the product is suitable for use in high pressure, heavy washdown and dust-prone applications.

IP69K GORE® Vent

In food applications, indicators may be subject to rapid temperature change, whether due to operating conditions or wash down procedures. Extremes of temperature inside and outside the enclosure can result in expansion and contraction of gases, which in turn can lead to moisture and humidity becoming trapped inside. To avoid this issue, the Avery WeighTronix IP69K certified indicators are fitted with GORE® Vent technology; a membrane which allows the indicator to breathe without compromising the IP69K enclosure. This industrial, food-grade technology guarantees no down time due to water ingress.


The ZM300 series of indicators offers multi-connectivity, ensuring compatibility and communication between old and new peripheral technologies. An Ethernet port is included as standard, supporting fast and efficient data transfer both locally or across the globe via an IP network, while two RS232 serial interface ports provide for data transfer to older equipment. A USB host port facilitates communication with printer hardware as well as offering the option of using a USB storage device to transfer data to a back office PC for integration and management. Analog output, USB device, Current Loop, RS485/ RS422 and Ethernet wireless options are also available, enabling you to utilize the same user-friendly interface for numerous applications with a range of connectivity options to suit your business requirements.
