Scale Magazine Comparison Series                       

The most popular pages of this magazine are the comparisons between like-models of various scale companies.  We feel that it's important to compare and contrast like models in order to understand the differences between them.  After all - scales that look similar are often completely different.  This leads us to this week's comparison between a generic brand Match Box scale, (available under several importers' names) and the Jennings Matchbox Scale M2.  These two scales are both interesting scales because they are very small yet have a design that makes them well suited to use for tobacco smokers and lots of other uses. It's not uncommon to find these scales selling for around $30 on the net.

Both of these particular scales share a sort of similar shape.   We feel that these two scales mark the best overall design of any super-mini pocket scale.  They are both small in size, but their expansion trays (cover upside down) expand the weighing surface. Their expanded weighing tray is as large (or larger) than many other pocket scales (including scales that are much larger in overall size).   This is an important new design trend where form follows function - yet at least for the M2, the design is still very beautiful.

Testing Results:

We tested 5 of each scale in their 50g x 0.01 versions but we also had them in various capacities including two of the generic brand scales in 500g x 0.1 version, one Jennings Matchbox Scale M2 in 250g x 0.05 version and one of the Jennings in 250g x 0.05 (pictured). All scales were put in a 70f room and allowed to sit for over 24 hours before tested.   Our test facility is a controlled environment that allows us to fully evaluate scales.  First (if possible) we calibrate the scales using a 50gram F1 weight.  We use F1 test weights for all of our tests and record the results on a spreadsheet to fully compare the products.   Each scale is tested by placing a 0.5, 1, 2, 5, 10, 20,  and 50 gram weight on the tray 10 times.   The results are then compared for an overall accuracy number, skew (reproducibility) and stability.  Then we put the scales into a 45f refrigerator for 30 minutes,  removed them and then ran the tests again in order to test for temperature compensation.

There was a substantial difference in the accuracy of these two models. We found the Jennings Matchbox Scale M2 to be substantially more accurate then the generic brand model.



Cosmetically there was a very big difference between the two scales. This is because the generic brand model only uses a thing paper sleeve for it's outer stylized cover.  The Jennings uses a fully finished painted plastic cover. The generic brand model has an outdated appearance when contrasted with the ultra-modern appearance of the Jennings. If you look at the photos, you can see how the Jennings has a beautiful, large oval LCD with three round buttons whereas the generic brand scale uses a basic LCD with two basic buttons. Also the generic brand scale model is more square-ish with the Jennings having a more rounded smoother appearance.

The Jennings comes equipped with their "Dual Weighmeter®".  We have written about this invention before;

" The Weighmeter is a patented invention we fell in love with last year. A digital graph shows that gets bigger and bigger as you reach the capacity of the scale.  With a dual Weighmeter, it wraps around the LCD until when you finally reach the capacity of the scale it shows "Overload".  The manner in which it is done on this scale, it adds a new level of confidence to the weighing process.  It is also fun and definitely futuristic.  "

Both Scales have an integrated expansion tray

The Jennings is operated by three rubber buttons,  On button acts as On and Off, one is to Tare/Zero the scale and the third button changes the weighing modes. 

The generic brand scale is operated by two plastic buttons  One button acts as On, Off and Tare (hold the button for 5 seconds to turn the scale off) and the other button changes the weighing modes.  


While both scales are nice, the Jennings Matchbox Scale M2 is our hands-down favorite over the generic brand scale. The Jennings has a much nicer finish, larger LCD, was easier to open, has more features and a fully painted cover instead of the thin paper cover on the generic brand model.
