A&D Precision Top loaders- FX-i and FX-iWP Series entry-level precision balances are fast weighing systems that are specifically designed to withstand shock and stabilize weights quickly and accurately. The FX-iWP series is also both dust-tight and waterproof, making it a suitable top loader for weighing powdery substances or liquids. It is also protected against water jets (complying with IP65). The scales have a full-featured 0.01g to 1mg resolution balance and are externally calibrated. One of the biggest selling points of this series is the patented Compact Super Hybrid Sensor, a one-second weighing response system (SHS) that is perfect for labs or environments that rely on fast results. A Statistical Calculation Function (SCF) also produces statistical data or output of weighed samples. The balances output all weighing data to a printer or personal computer using an RS-232C serial interface. A USB interface is optional. Several weighing modes and units can also be selected for specific applications and can be displayed in a counting mode, percent mode, or a programmable unit. A specially designed internal shock absorbing system helps offer added protection against transverse overloading and vertical overloading.
