The GC803P has been discontinued by Sartorius.  Please review either the Sartorius GCA1603P or GK703 as an alternative.

Dual range high precision analytical balance with internal calibration, RS-232 interface and the new innovative triangular weighing pan shape.  The PolyRange consists of a fine range [0-200ct x 0.001ct or 0-40g x 0.2mg] and a high range [200-800ct x 0.01ct, 40-160g x 2mg].  The GC803P comes standard with built-in RS232, glass draft shield, motorized internal calibration, dust cover and gem cup.  This is a gorgeous carat scale offers fast and accurate weighing of individual gemstones as well as larger lots and is a true gem.  Precision Weighing Balances is your source for high-performance Sartorius Weighing Technology at affordable prices.

The GC803P features the patented "monolithic" weigh cell technology for spectacular performance.  The monolithic block is made from one piece of a special metal that is robotically etched, resulting in a more rugged design with high-level weighing results and less sensitivity to temperature fluctuations.  With this patented system, Sartorius sets the technological standards ­ for the new millennium.

The Monolithic Weigh Cell offers unbeatable advantages for daily use like Incredibly fast response time and Unfailing reliability and near-zero susceptibility to interference.  The reasons for these considerable advantages are two fold: the number of individual parts has been reduced by more than 70% and the mechanical construction has been designed to last for years of trouble-free operations.

The GC803P offer 16 weighing function so it's perfect for measuring in grams, carat, milligrams and more to meet just about any weighing application.  Review all the technical specifications on the GC-803P here .

Before purchasing any diamond scale, be sure you review the Sartorius GD503.   Nothing compares in price, quality, and value.  We keep the GD503 in stock and ready for immediate delivery.  The GD503 carat scale offers legal for trade(the GC803P is not LFT), RS232 interface, 3 year limited manufacturer's warranty, and even includes 100 gram calibration weight.
