Magnum-1000 Digital Jewelry Pocket scale 1000 x 0.1g Review

Average Reviews:

(More customer reviews)I received this scale in the mail today.It was shipped promptly.It is smaller than I imagined, small enough to fit into a shirt pocket.The weighing platform will hold a paper cup but not anything much bigger.The batteries are included.A thin plastic strip must be removed from the battery compartment before using.I used a set of gram calibration weights from my long-ago college chemistry class to test the unit.At first I was impressed.The digital readout said 1.0 with a 1 gram test weight, 10.0 with a 10 gram test weight, and 50.0 with a 50 gram test weight (my largest).Then I tried weights less than one gram.I was disappointed that the scale read 0.1 less than the actual weight.For instance, the scale read 0.6 with 0.7 test weight.I then tried the 1 gram weight again and it read 0.9.So the accuracy is plus or minus 0.1 gram.For instance, if the scale reads 7.2 grams, the actual weight could be anywhere from 7.1 to 7.3 grams.This is close enough for my application.I did not expect a highly accurate scale for $21.The unit shuts off after 1 minute unless you add or remove weight.That is an annoying feature but it is easy to turn the scale back on.There is a calibrate button that requires a 500 gram weight (not included).A mode button chooses units: grams, ounces, etc.A tare button zeros the readout.There is also a button for counting pieces.This scale will be satisfactory for my occasional use.
