Compare all the features and specifications and you'll have a hard time to matching the value the Sartorius GCA2502 provides to meet your weighing needs and the deep discount prices we offer.  Can't decide what to buy?  We can help you decide very fast by offering you 500 grams weighing capacity with 1 milligram readability.  Call the other guys and see what they want for 500g x 1mg and we doubt it will be anything near the Sartorius GCA2502.  Plus the Sartorius GCA2502 comes with the motorized internal calibration

Just press the CAL button and the internal weight calibrates your GCA2502 for consistent accuracy.  If you forget to calibrate the balance don't worry the isoCal allows the balance to be preset to perform calibration automatically or prompts user to calibrate, plus it monitors adjustments through GLP-compliant printouts when purchased with a printer. 

The GCA2502 offers a large triangular weighing pan with a 4.3" diameter, and a high quality 3 door draftsheild that is removable.  Lots of other milligram balances on the market have a cheesy low cost draftshield but the GCA2502 is high quality and it is removable for easy cleaning.

High performance carat scale well suited for office, workshop, and production applications.  Weigh 2500 carats with 0.005 carat readability or 15 other weighing modes like 500 grams with 1 milligram readability.  Standard equipped with the GCA2502 is an RS-232C data interface for connecting the scale to a PC or printer, removable glass draft shield.  This is a beautiful balance made in the USA and perfect for any lab and a price you can't pass up.  Similar to the motto location, location, location for real estate with the name Sartorius it is synonymous with quality, Quality, QUALITY.

The GCA2502 is the ultimate milligram balances for the lapidary marketplace.  The GCA2502 has very similar features to the Sartorius CPA423S but sold for hundreds less.  Basically, the gem market place is extremely price sensitive market sector verses the laboratory marketplace so Sartorius developed the GCA2502 with a special price to meet the pricing requirements for the jewelry marketplace.  Whether your weighing diamonds or chemical compounds the GCA2502 weighs from 0 to 2500 carats (0-500 grams) weighing capacity in 0.005 carats (1 milligram) intervals.  Please note the draftshield is shorter in height measuring only 6.37" (from pan to top of glass door).  Built-in applications programs include: mass unit conversion by toggling; tare memory; net total formulation; weighing in percent; counting (5, 10, 20, 50, 100 pcs); and animal weighing/averaging.

The GCA2502 produces steady readings using the high stability mode and the unique Sartorius weighing system even if the environmental conditions are not ideal for precision weighing.  The Double Lever System, or DLS, for short based on its special force transmission design.  With this patented system, Sartorius sets the technological standards ­ for the new millennium.  Patented, this new "small" system is cut from a single block of a special, highly rugged aluminum alloy using high-speed 21st century milling technology.  The double lever principle offers two decisive advantages: the design in the area of the pan linkage is highly resistant to mechanical stress and therefore has exceptionally high mechanical stability, and the system is about half the size of the monolithic block cell, allowing for a smaller footprint.  Like the monolithic weigh cell, it is cut from a single block of aluminum and no screw fasteners are needed between functional parts.  This keeps the system less sensitive to fluctuations in temperature, and with fewer parts there is less chance of failure.

Review all the specification below by scrolling down this web page and we think you'll agree this is the ultimate milligram balance at an unheard of price.

Sartorius is the choice when you need superior weighing technology and Precision Weighing Balances is your authorized distributor for the full Sartorius gem balance line at discount prices to the public.

When you purchase a Sartorius GCA2502 milligram balance you can also purchase a data printer for special price!
