AN404 Load Cell Tester
The ANYLOAD AN404 Series is a portable load cell tester designed for comprehensive bridge resistance, insulation, and sensitivity measurements in laboratory and field environments. This portable instrument measures bridge resistance, insulation resistance (500-10,000 MΩ), input and output resistances, and zero balance with high precision, making it essential for load cell calibration, verification, and troubleshooting.
The 7-inch touchscreen interface provides intuitive setup and real-time measurement display, while per-channel calibration and automatic settings retention ensure consistent performance across testing sessions. The AN404 is equipped with RS-232 communication and Modbus protocol support, enabling integration with automated testing systems and data acquisition platforms. With a measurement range of 0-4000 Ω and accuracy of ±0.5 Ω below 2000 Ω and ±1 Ω above 2000 Ω, the tester delivers precision results for quality control, load cell manufacturing, service centers, and research laboratories.
The instrument supports multiple international plug types (Type-B, Type-F, Type-I, Type-G), making it suitable for global deployment. Ideal for load cell manufacturers, system integrators, maintenance technicians, and equipment calibration facilities requiring portable, high-accuracy load cell diagnostics.
