Useful Weighing Bowl The CJ4000 includes a weighing bowl for all those tough weighing jobs that require a container. The bowl holds approximately 750 milliliters, and is 8.4 inches by 6 inches. This bowl can also double as a dust cover for the scale when it's not in use.
Auto-Off Feature If ya have ever had the batteries in something run out because you forgot to turn it off, you'll realize what a blessing this feature is. The CJ-4000 will automatically turn off after a few moments of inactivity.
Bright Backlit Display This table top scale has a fancy backlit display to help ya see your weight readings, even in dim lighting. Not only that! This digital scale's display will tell ya if ya pressed the tare button, and the unit you're weighing with.
Does This Thing Count? You bet it does! All ya need to do is weigh a sample amount of pieces, so the scale can know how much each piece weighs, then start counting. You'll be finished in no time.
Tare Feature The tare button on the front of this diet scale can be pressed to "zero out" the weight on the scale. You can then add more weight, and the display will only show the weight of the item you're adding. This sure is useful when ya want to get the weight of each ingredient for that delicious recipe.
Stainless Steel Platform This compact digital scale has a durable stainless steel weighing platform to make cleanup a breeze. Unlike gold or silver, stainless steel doesn't scratch easily, and it keeps its shine without rusting or tarnishing.
It Remembers The Last Unit Ya Used If your application needs weights in the same unit of measurement, (like ounces for instance), it can be a real pain if your scale always turns on ready to weigh in grams. It's a good thing the CJ 4000 turns on displaying the unit of measurement you were using when ya turned it off. This can come in real handy if ya want to use the CJ4000 as a postal scale.

We bought this unit 4 years ago from Will Knott Scales. We have a rock and mineral shop and have literally weighed thousands of rocks and minerals on this unit without ever having a problem. The accuracy of this scale has been consistent from the first day we turned it on. It takes a beating and remains accurate. We test the calibration monthly. The batteries last a long time. We absolutely recommend this scale for weighing rocks and minerals!Reviewed by: Danny Edwards from Hendersonville, North Carolina on (12/23/2014)
Ordered with USPS Priority Mail, arrived in 2 days! From the mainland to Hawaii in 2 days, that's lightning speed fast! When I ordered it the description stated charger not included, and I forgot to include the charger (arrgh!). I was just about to order one when my package came in, and it came with the charger included!!! Great service, fast processing, insanely fast shipping.

I purchased the Jennings Model CJ4000 scale from Old Will Knott Scales and the customer service is outstanding. My order was handled promptly and I received the scale within three days from my initial order. I bought the scale for it's 4000 gram or almost 9 pound capacity and it's 0.5 gram or .018 oz resolution. I have not been disappointed in it's accuracy. The reason for my purchase is to weight backpacking equipment. My treks include hundreds of miles at a time and it is extremely important to know how much each item I carry weighs so I can keep my overall weight to a minimum. The scale runs on batteries and comes with an AC adapter and cover. If one is to maintain the accuracy of the scale it is important to keep the scale covered to protect the platform from dust and debris. It also has a backlit display, which is a great feature, and a tare feature that I can use to measure the total weight of all the ingredients in my trail recipes. Excellent service and an excellent product. You won't be disappointed with Old Will Knott Scales.Reviewed by: Doug from Sandy, UT on (4/2/2014)
I got this scale to weigh food and gear for backpacking. It serves the purpose very well. I can easily compare light items like plastic drink bottles to pick the lightest gear. It's great for assembling equal-weight packages of food for each day.Reviewed by: John Joyner from Central Coast of California on (5/4/2013)
I love the scale. It is small but holds a lot. I use it for measuring glaze for ceramics.Reviewed by: Darla Eggert from Northern Maryland on (4/23/2013)
Great item...glad I bought it!!Reviewed by: Mark Beattie from Kansas on (6/11/2012)
I got this scale the better to doctor my tennis racquets with lead tape. A 1.0 gram resolution probably would have been ok, but I'm really glad I got this scale with the 0.5 gram resolution. Works great, easy to use. Really fast delivery from Old Will, too.Reviewed by: Jeffrey from Seattle on (2/25/2012)
Works as good as balances that cost 3 times as much. Very accurate and good battery life. I like the cover that is included as well. If it continues to function like it has I will purchase more.Reviewed by: Jim from Illinois on (2/10/2012)
Excellent product for the price. Very well made! I teach high school freshmen and you know how abusive they can be with equipments.Reviewed by: Carl Hinote from Oklahoma City on (12/21/2011)
Good scale. It is well designed with the cover doubling as a weighing container. Display is large enough to see easily w/o reading glasses. Would recommend.Reviewed by: Mike Buchholz from South Dakota on (12/12/2011)
Questions and Answers
A: Hey there Mach,
The CJ-4000 will be able to count up to 999.999 pieces, weight limits and amount of pieces permitting. It depends on the weight of the pieces you are trying to count and the effect on the relationship between the resolution, which is 0.5 grams, and that maximum capacity. Also, how many pieces your sample weight is set for.
A: Hey there Seattle Rain,
The CJ4000, as with most scales, comes factory calibrated. The frequency of usage, the load being weighed, and the environment in which the scale regularly weighs will determine if the scale needs to be calibrated more often. To calibrate it, you will require (2) 2000 g weights: http://www.oldwillknottscales.com/2000-gram-calibration-weight.html
The AC adapter for this scale has an output of 100-240 VAC and an input of 6 V. The part number for this adapter is JSCALE-ACADAPT-CJ300-CJ600-CJ4000.
