Digital Weight Indicator

With the 120/120 Plus digital weight indicator, there is no need to sacrifice quality for price. These digital weight indicators are designed to be a reliable, cost-effective solution for material handling or shipping and receiving applications. The 120/120 Plus drives up to four 350Ω load cells while three-stage digital filtering provides stable, accurate weight data. The 120/120 Plus's tactile front panel and easy-to-read display help to make scale operations effortless. Two independent communication ports provide full EDP and print ticket programmability.
