A&D has discontinued the SK-Z Series and there is no remaining stock. We recommend the CAS SW-1-50LB as an alternative for the SK20KZ. The CAS SW-1 is a lot less money and this is why we think A&D Weighing ended sales for the SK-D Series. All information displayed herein is for archival and support purposes only.

Great for soil sampling for environmental consulting companies.  There is practically nothing on the market today that offers an offset stainless steel platform with huge 1 inch LCD.  The SK-20KZ is perfect for weighing buckets of soil for land reclamation studies.  Lb/Oz Version, NSF Certified, but NOT Legal For Trade.

The A&D SK20KZ is also purchased by fishing clubs as their official tournament scale.  Simply place a laundry basket on the platform, press the "tare button" to zero the weight of the basket and throw those fish in to see who is the winner of this weeks big fishing tournament.  The large 9.05" x 7.48" stainless steel platform with the 1 inch LCD display position several inches below the platform makes the SK-Series a breeze to read the winning weight.

You can either scroll completely to the bottom of this web page to see the entire line of A&D SK Series Digital Scales or read all the specs in detail here & view additional pictures of the digital scale.

A&D electronic scales are an excellent retail weighing solutions, but often times our customers call looking for a lower cost digital scale to get the weighing application done for less money.

If you require a Legal For Trade, NTEP Approved, Class III Scale since you are using the scale in a commercial applications where product is sold by weight, we recommend you look at the CAS SW-1-50LB (SW-20) digital scale.  The CAS SW-1-50LB big selling point is the digital scale weighs in Pounds, Ounces, Kilograms or Grams.  Oh, another huge selling point is the CAS SW-1-50LB comes standard with the AC Adapter, while it is a pricey option on the SK20KZ.
