440 gram weighing capacity with 0.001 gram readability, internal calibration, 3 year warranty, a full draft chamber all for under $1500!!  Even better we have several GK2202 in stock for immediate delivery - we stock balances verses even the manufacturers now maintain no inventory and build everything to order in the new economy. When the manufacturer gets an order it takes WEEKS to ship but not here at Precision Weighing Balances since we stock.

The GK2202 also weighs in carats.  Carat weight affects prices of diamonds dramatically and determining the accurate carat weight is critical for anyone in the jewelry industry.  Many people think of carat weight as the size of a diamond.  However, two diamonds of the same weight can look very different in size.  If a diamond is cut deep and narrow, it will look much smaller than another diamond of the same weight that is cut shallow and wide.  The jeweler with a Sartorius GK2202 on their showcase counter top could be the competitive advantage of a customer choosing your jewelry store over the guy next door.  When a customer sees a quality high precision balance in your store this builds confidence the client is getting what they are paying for.

Like a fine piece of jewelry Sartorius is a German company and maker of some of the world's finest balances since 1871 when they introduced the world's first pharmaceutical balance.  Only Sartorius shatters the limits when "the Guinness Book of World Records" listed the Sartorius Model 4108 as the most accurate balance in the world.  Sartorius' excellent reputation and image in the technologically sophisticated field of weighing balances make them a global leader.  Sartorius brand image is recognized throughout the world in the jewelry and geologist marketplace as the weighing standard.

Sartorius GK2202 Carat Balance offers 0-2200 carats weigh capacity and increments in 0.005 carat divisions (0.005ct, 0.010ct, 0.015ct ...).  You can choose from over 20 different weigh modes like grams (440g x 0.001g) plus you can toggle between 5 different weigh modes.  The balances also features selectable application programs from percent weighing for formulating solutions; density determination to verify the authenticity of a gem; to count function for counting findings and small beads or rhinestones.

The GK Series are also quick and easy to clean with its removable side-doors and stainless steel construction.  Calibration is simply a press of the button with the motorized built-in internal calibration standard on all Sartorius GK & GW Gem Balances.  Intuitive high contrast backlit display with icons to tell you at a glance which application you are using with the new Gem Extend Series.  You can also change the language to German, Italian, Spanish and more making the Extend Series the bilingual jewelry balance of the world.  Text prompts and cursor keys for navigation make it so simple for you to configure the balance to meet your individual requirements..

The latest technology.  Sartorius utilizes 21st century technology, such as the unique robotically etched monolithic weigh cell, which ensures long-term high accuracy.  The Sartorius Extend series features the latest powerful microprocessor technology, shortening the response times for faster results.  Reliable weighing results, all of the time - even under less than ideal ambient conditions, thanks to the Extend´s highly sophisticated digital compensation algorithms.
Ease of use.  When you need to get a heavy workload of repetitive applications done fast and reliably, day and day out, the last thing you need is a gem balance so complicated that it causes operating errors and wastes your valuable time as a result.  Welcome to your new Extend balance comfort zone: a simple, easy-to-understand control panel, key function assignments and the easy-to-read display are ideal for efficient weighing in your lab.  User-friendly operation: short, plain-English text prompts and cursor keys for navigation make it simple for you to configure the balance to meet your individual requirements.  Outstanding readouts thanks to the backlit and high-contrast display (height of digits: 15 mm).  The level indicator is positioned conveniently right next to the display so that checking whether the balance is level becomes "second nature" to the operator.

They promised you accuracy.  They promised you speed, easy of use & affordability.  They promised you the perfect balance but only Sartorius delivers weighing nirvana with the new Sartorius Gem Extend Balances.  When you need to weigh and you want to best prices on Sartorius Gem Balance Precision Weighing Balances is your authorized stocking gem dealer.  You can see the complete offer of Sartorius GK & GW carat and gold scales at the bottom of the page.
