A&D FX-300i (FX300i) Precision Balance, 320 g x 0.001 g, External Calibration, with 100 g Calibration Weight

Description

A&D FX-300i Precision Balance: 320 g × 0.001 g

The A&D Weighing FX-300i (FX300i) is a 320 g, 0.001 g precision balance from A&D’s FX-i series. A&D’s patented Compact Super Hybrid Sensor (C-SHS) settles in about one second, so you get milligram results quickly, whether you are weighing powder charges, gemstones, or lab samples.

The bright vacuum fluorescent display is easy to read from any angle, the small breeze break shields the Ø130 mm pan from drafts, and the standard RS-232C port connects to a printer or PC. MNM Scales includes a free 100 g calibration weight with this listing, so you can calibrate it yourself on day one.
