The Optima OP‑903 Accumulation Indicator is a powerful, portable weight display unit designed specifically for axle scales and multi-pad weighing systems. Built with durability and efficiency in mind, it features a large backlit LCD display, integrated printer, and multi-pad support, making it ideal for vehicle weighing, logistics, and compliance operations.
Its key strength lies in its ability to accumulate weight readings across multiple passes or pads, automatically totalizing and printing comprehensive weight reports. With support for up to four individual weigh pads, it allows for quick and accurate monitoring of total load and axle weight distribution.
Encased in a rugged mild steel housing with splash-proof controls, the OP‑903 is engineered for tough field environments. Combined with battery-powered operation and versatile connectivity (including RS‑232 and optional wireless), it delivers both mobility and performance for field operators, freight companies, and agricultural transporters.
Whether for mobile weighing stations, in-yard check-weighing, or DOT compliance checks, the OP‑903 offers a complete, self-contained weighing and reporting solution.
