This is one of Revain's cheapest AC scales. I don't think the reading is entirely correct - in fact I know it isn't. This is close enough to work with automotive air conditioners. I have a mechanical shop and have used it dozens of times. Holds up well; I can recommend using a slightly more expensive scale if you need accuracy.
