Hands On: American Weigh 100g x 0.01g Digital Scale

Here’s a Hands On Look at American Weigh’s Model AWS-100 Digital Gram Scale.  The scale has 1/100th gram resolution making it great for accurately weighing hops, small amounts of specialty grains and water salts.  It has a 100 gram (3.52 ounce) capacity.

100g Calibration WeightI purchased this 100 gram Calibration weight at the same time I got the AWS-100.  It’s worth picking up one of these.  You’ll see why next.

AWS-100 100 gramsThe 100 gram weight reads 100.12 grams.  The manual states that “calibration and adjustment are performed at the factory.  However, the weighing range can shift slightly during shipping”.  If the scale is weighing within an acceptable tolerance the scale should be left alone.  If it is outside of tolerance, it should be calibrated.  The manual says that the tolerance for this scale is .02 grams.  .12 is 6 times acceptable tolerance.  Calibration is required.

AWS-100 CalibrationTo calibrate you hold the mode button until CAL appears on the screen.  Press Mode again and it prompts you to put a 100 gram calibration weight on the platform

AWS-100 calibrationPut the weight on and the… wait :) and the scale will pop up pass.  I’m guessing it calibrates itself using the weight and then re-tests the weight to ensure that it’s within tolerance.  If it is… whammo… pass.

AWS-100 100 gramThis is a different 100 gram weight.  It reads right at 100.

A note on accuracy: I don’t have lab quality weights.  Slight variances in this accuracy tests could be a reflection of either the scale or the weight or both.  My guess is both are generally to blame.  If 1/100th (one one-hundredth) of a gram is an issue for what you’re doing… you’re going to need a lab quality scale.

AWS-100 Homebrewing reviewReads .21 with a 200 milligram calibration weight

AWS-100 Homebrewing reviewReads .11 with a 100 milligram calibration weight.  Getting a reading on this light of a weight verifies that this scale is good for both hops and water salts.  It’s not really necessary (at least in my book) to get down to tenths of a gram for hops (although it’s nice to be able to do).  It is necessary to get down to this range for water salts.

AWS-100 Homebrewing reviewWeighing 28 grams (about one ounce) of calibration weights using the AWS-100.  Hops and water salts are a couple of things that I like to weigh in metric.  The other is… yeast starter wort.  That is very easy to formulate using liters and grams.  1 liter of water goes with 100 grams  DME.  If you need a .5 liter starter it would be .5 liter of water + 50 grams of DME.

cln_img_6910Weighing a stainless sample cup (part of my Brew Day Box).  This is a good example of the beauty of the Tare Feature.  Notice that the scale reads 39.45 grams.

AWS 100 tareA press of the Tare button effectively zeroes out the scale.

AWS 100 hops scaleBecause the container is subtracted, I’m weighing just the contents.  That means I have 35.22 grams of Amarillo hops here.

aws-100 gram scale reviewOne thing I have wondered is… Can you weigh more than the capacity of a scale using the Tare Feature.  The answer, at least for this scale, is yes.  I put a 100 gram weight on the scale, Tared it and then put a 50 gram weight on the scale.

This is a great scale with excellent resolution and accuracy that is perfect for hops and water salts.
