🔧 Cozy Precision Calibration Set – Precision Weight 10mg and 100g Review

Could have used a better box but it comes with a box that does the job, if it falls it's no use. Mine is fairly stationary so I'll probably never need a second set unless I lose parts. Bad Comment: Cheap tweezers get what you pay for so get the best set if you want to look professional in use.

These weights are accurate to +/- 0.01g based on the Ohaus Scout II (400 x 0.01g ). I have a very cheap "50 x 0.001g" scale but I have found that its actual performance is no better than 0.01g despite the 1mg number. It also "snaps" to 0.000g instead of showing true drift, so you can't measure small weights.

This is an EXCELLENT set of weights! My scale has an accuracy of 0.001, so I studied the exact weight seriously for almost a month before buying it. I bought it in May 2020 and have been using it daily ever since. At 0.001 your reading is only affected by air displacement (e.g. from the air conditioning or your breath) which is why my scale has a lid with a small hole at the top for you to lift it. I have to close this little hole for true accuracy or it will drift off. I also calibrate it…
