Proba-Weigh ® Variable Fulcrum Balance
by Charles Scamahorn © 2005
The Proba-weigh gram balance in its small form is a variable fulcrum balance for weighing small items which is accurate, robust and easily carried in one's pocket. It requires no batteries or special care. It does require good vision and a tiny bit of skill. It offers two decimal place accuracy between 0.5 grams and 10 grams. With caution it can be read with one decimal place accuracy to a low of 0.01 grams and a high of 100 grams.
