A honey of a little digital scale, the techies in the back room say. This improved Triton T2® scale is pocket-sized (5-7/8" x 3-1/8" x 3/4" thick), and measures up to 300g x 0.1g, 10.5 oz x .005 oz, 190 pennyweight x 0.1 dwt, and 9.6 Troy ounces x .001 ozt. Has a zero/tare button and a cover that can be removed for use as a larger tray. Comes with (3) "AAA" batteries.

This (10) piece set of weights are brass cylinders topped with knobs. The weights are stamped on the top. There are (2) each of 1, 2, 5 and 10 grams, plus (1) 20 and (1) 50 gram weight. Our each is the full set of 106g. 

About 1/100 of this solid brass 100g cylindrical weight. Measures 1" dia x approx 15/16" tall with a 7/32" ID cup hook at the top. Pretty. Useful for calibrating scales. And accurate to within one percent, which is one reason for this great price, because if it hit 100g on the head every time, we'd be charging you a heck of a lot more.

This isn’t one of those antique scales of justice you see in law office logos, but it works like one. Technically a “balance,” ours is plastic, from SI Manufacturing, and just right for middle-schoolers. Measures 12” wide x 5-1/4” deep x 4-1/2” tall. Has a 10g beam for fine adjustments, accurate to .5g, (2) removable pans that are 4-1/4" square at their base and 4-11/16" on top with 1" high sides, and a (7)-piece brass mass set that fits in holes in the base of the balance—(2) at 50g, (2) at 20g, and (3) at 10g. Includes an activity guide with several experiments for students to learn about balances and mass. Also has a centering slide weight on back to zero the balance. Please unpack carefully; this is a finely tuned machine, like you.
