My Weigh i500 500g x 0.1g (17.635 oz x 0.005 oz) The i500is a professional compact scale with a backlight and extra large LCD screen. The backlight makes it easy to read from a distance. Each scale now comes with a large Stainless Steel tray, parts counting features and 6AA batteries. Scale professionals know that "multiplied" sensors simply won't cut it when accuracy and durability count. The i500 uses a true 5000 division load cell. These commercial grade sensors make this scale incredibly accurate and durable. The i series also has an integrated thermistor to compensate for temperature changes and auto zero tracking to ensure stability.
