Weighing your resin and activator is the most accurate way to measure them for mixing in the correct ratio. These pocket-sized digital scales are accurate to ±0.1 g and are just the right size for a mixing pot. Remember to tare (zero) the scales with the empty pot before dispensing the resin and hardener. We recommend covering the scales with plastic (e.g. put them in a clear plastic bag) to prevent them being ruined by epoxy drips.
The scales are factory-calibrated but can also be easily recalibrated. They are powered by two AAA batteries, which are included.
