The HOLI HL-703 is a trusted weighing controller and indicator designed to work smoothly with all kinds of weighing instruments and weighing scales. It gives fast and accurate weight readings, making it ideal for use in factories, warehouses, and production systems.
With a clear digital display and user-friendly buttons, the HL-703 is easy to operate, even in busy work environments. Its compact and strong design makes it perfect for panel installation, saving space while giving you full control.
This reliable weighing solution is great for tasks like batching, filling, and process control, helping improve efficiency and reduce errors in daily weighing work.
Key Features:
High-quality indicator for various weighing instruments
Compact weighing controller with easy-to-read digital screen
Suitable for all standard weighing scales
Fast, stable, and precise weight readings
Ideal for building complete weighing solutions in industrial settings
The HOLI HL-703 helps you manage weight control with confidence – it's accurate, simple to use, and built for long-term performance.
Specially suitable for1-4 types of material batching scales in the concrete industry, reducing scales with automatic feeding function, batching scales and packaging scales for dry powder mortar, and liquid filling scales.
Dynamic detection, digital filtering technology, and automatic zero point tracking function.
High precision and high performance A/D conversion, effectiveA/D conversion rate of 300 times/s.
Multiple dosing modes:1~4 material incremental dosing modes, single material reduction dosing modes and free preset point modes.
Automatic feeding automatic unloading,automatic feeding manual unloading, manual feeding automatic unloading and manual feeding manual unloading and other working modes.
With advance automatic correction function.
MT technology and EMC, RFI, environment(low temperature-40, high temperature+80℃), impact, drop and other tests, greatly improve the stability and reliability of the product.
Support a variety of communication data formats: continuous output format, command output format, ModBus RTU format ,etc.
Standard Serial port: RS485 or RS232.
Optional: ProfiBus DP bus/16 bit analog/4-in 8-out input/ output.
