Pros: Highly accurate scale to 0.002 grams, portable, tare capability and compact.
Cons: The limit of this scale is only 10 grams.
I have used the Gram Precision DiaGem Carat Scale for 6 months now to determine the masses of meteorite specimens. Some meteorites sell for as much as $250,000.00 per gram in small quantities and the DiaGem scale is the perfect scale when accuracy is a must. This scale is accurate to 0.002 grams. It is compact, batery opperated and can mass in grams or carats, making it a valuable tool for the scientist and the gemologist alike. The scale comes with a draft shield, carrying pouch and 5 gram callibration weght. The instruction manual is easy to read and understand. There is a tare feature and a a memory feature as well. Also included is a tray for containing very small items. I have used a number of precision scales over the years and the DiaGem Carat Scale, model CT-50, is far superior to all other moderately priced scales with similar features. I highly recommend this scale to anyone who reqires accurate massing of small specimens.
