Most pocket scales measure only up to 100 grams, but if you need to weigh a bit more check out the Triton T2.
Offering the portability you need in your pocket scale, this unit is designed to measure up to 400 grams in 0.01-gram increments. Engineered for long-lasting accuracy, the scale has digital auto-calibration and tare feature.
The hardcover of the scale doubles as a weighing tray for loose items, and the red backlit display makes results readable in any lighting condition. Batteries are included.
