American Weigh Scales Table Top Postal Scale, Black

This review is for the American Weigh Scales (AWS) PS-25 digital postal scale. I purchased it from EZ Sell via Amazon. It was shipped by EZ Sell and it arrived in only 3 days from the order date with standard (free) shipping.

The PS-25 has a maximum capacity of 55 lbs and a sensitivity of 0.1 oz (minimum capacity is 0.2 oz). The scale comes pre-calibrated and I tested it with a calibration weight that I already had and it seemed to be in perfect calibration. Note: If you want to manually calibrate the PS-25, yourself, you will need a 10 kg calibration weight. Such a large calibration weight is usually expensive. The cheapest one I could find is by the same manufacturer (AWS) and cost US$99.99 with free shipping which is almost 5 times the price of the scale, itself.

The PS-25 arrived with the platform uninstalled. Installation was easy---just align the six mounting studs to the mounting holes on the metal sub-plate and carefully push the platform onto the... Read more

I bought this scale for ultralight backpacking--needing something that measured to the 1/10 of an ounce. I was interested in this scale (1) because of its accuracy, and (2) it it is larger than most kitchen scales and can more easily handle bulky UL backpacking gear.

However, once I got it home and began using it, I realized that I wasn't getting any odd-numbered decimal points on my readings. It turns out that it is only accurate to the 1/5 of an ounce.

That being said, it did work very well--just to 0.2 not to 0.1 as it claims.

I checked out at least 10 different scales before deciding on this one and I am very happy that I chose to buy this one. Not only does it weigh up to 55lbs but the price is much lower than many scales that only weigh 10 - 50lbs. Also, it came fully calibrated out of the box. I put on my 100G calibration weight (3.52739oz) and the weight came up 3.6oz, which is exactly what you want. It only shows one decimal place on the screen so you want it to round up. It's small and compact and the buttons are easy to see and use. As long as it keeps working, I'll be very satisfied.
