Designed to address the needs of both highly integrated and stand-alone industrial weighing applications, the HI 6800 Series serves as an all-in-one weight controller.The Model HI6800 is designed for weight-based control of applications such as level monitoring, set-point control, static checkweighing, and piece/part counting. The model features an optional HI6130 (4.3-inch color TFT touchscreen) for operation and setup.

Featuring dual-port connectivity and an embedded network switch, the HI6800  makes serving up data to both control networks and information networks simple and safe.  Choose from the most popular Industrial Fieldbus protocols for control networks: EtherNet/IP or Modbus TCP/IP; while reaping the benefits of IIoT device-level connectivity though a built-in Webserver. 

The Model HI6800 comes with two Ethernet ports, a microSD card slot, USB-C port, 2 digital outputs, 2 digital inputs, and a single analog scale input. The dual 10/100 Mbps Ethernet ports with integrated network switch are ideal for simultaneously linking the instrument to both control and information networks for monitoring performance, diagnostics, and process statistics. Data from the instrument can be easily served up to the Intranet, Extranet, VPN, and the Internet by utilizing the EtherNet/IP or Modbus TCP/IP communication protocols.

Featuring Hardy’s exclusive WAVERSAVER+®, even in noisy environments with excessive amounts of mechanical vibration, the HI 6800 provides a steady 1:30:000 resolution in oz, lb, ton, g, and kg at 250 updates per second.

Use Hardy’s exclusive C2® Second Generation Calibration for automatic system calibration to save hours in commissioning and routine maintenance.  By reading the calibration certificate electronically embedded in the C2® load cell sensor, the scale system can be calibrated with the touch of a button; avoiding time consuming and expensive traditional calibration procedures.

Comprehensive diagnostics are displayed for power, network, and weighing function status allowing users to quickly identify faults and solve issues by following on-board help instructions. With INTEGRATED TECHNICIAN®, maintain and troubleshoot the weighing system at the sensor level by diagnosing individual scale components (load cells) without the need to disconnect wiring.

The Hardy Process Toolbox is a set of productivity tools that support industrial weighing functions. Each tool saves time, increases accuracy, improves efficiency, or reduces risk in process weighing applications, including WAVERSAVER® to eliminate vibration, C2® electronic calibration, and Integrated Technician® to name just a few.

The HI 4050 features the following Toolbox technologies:

C2® (or eCAL) Electronic Calibration

The Hardy C2®  (or eCAL as it is known in China) core feature provides quick and easy electronic calibration of a weighing system without the need for heavy test weights.


Hardy's INTEGRATED TECHNICIAN (IT) core feature helps you troubleshoot your weighing system and diagnose problems from the front of the instrument or via the PLC. These tests display system weights, voltages, and pass/fail displays to help isolate a problem to the instrument, cabling, or sensors, helping to reduce maintenance costs.

WAVERSAVER® vibration eliminator

Hardy's WAVERSAVER core technology eliminates the effects that surrounding vibration has on the scale weight signal, providing only true data for fast, accurate weight reading.


A patent pending dynamic algorithm that improves the stability of static weight readings by 3X.

Embedded Web Server

Access your instrument from any computer browser, easing setup and making diagnostics fast and easy. Use the Embedded Web Server to set up all parameters from anywhere on the Ethernet network.

Secure Memory Module Stores Configuration Data

Hardy's Secure Memory Module (SMM) uses a standard SD card to automatically back up critical weighing system data, allowing you to transfer it to another like controller in a few minutes. You can also use the card to easily back up your controller data onto a PC.
