EX-650 Black Digital Coin and Jewelry Pocket Scale
Retailing for around a mere $7.00 at many online retailers, the W-EX650 measures a miniscule 10.2 x 7.0 x 2.4 cm, but don't let any of this put you off because WeighMax has built a sturdy little machine for weights and measurements. Suitable for use with just about anything, the weighing platform is great for jewels, food ingredients, whatever you need to weigh in small amounts.
The unit can accommodate up to 650 grams with a sensitivity of a tenth of a gram. You get four units of measurement with the W-EX650, grams, ounces, troy ounce, and carat, and there's a tare function available. Calibration is super simple and a luminescent backlit LCD display lets you read your results clearly and easy. All you need is a pair of AAA batteries and you're ready to go.
