A&D Weighing Apollo GF-224A Analytical Balance, 220 g, 0.1 mg
Capacity
220 g
Readability
0.0001 g
Repeatability
0.0001 g
The A&D Weighing Apollo GF-224A Analytical Balance, 220 g, 0.1 mg, with a capacity of 220 g and a readability of 0.0001 g, delivers high precision in a robust package, ensuring accurate measurements for various laboratory applications. This balance features external calibration with an easy one-touch button that not only performs but also documents calibration, ensuring consistent performance and compliance with lab standards. Its fast stabilization time of approximately 2.0 seconds, or 1.0 seconds with fast mode enabled by Smart SHS® Weighing Technology, significantly enhances productivity, especially in fast-paced environments.
Designed for versatility and user-friendliness, the GF-224A incorporates features like Impact-Alert, which visually and audibly indicates the magnitudes of impact shocks, and a Shock-log that documents the date, time, and level of shocks, protecting the integrity of your results. Additional advanced functionalities include a Flow Rate Display (FRD) that streamlines and improves the precision of filling or dosing tasks. The FR-Cal function calculates and displays outputs for the mass or volume flow rate by entering density, while FR-Compare provides feedback if the flow rate is within set limits. FR-Secure ensures that tare values are stored in non-volatile memory to prevent data loss during disruptions.
Operational simplicity is achieved through its user-friendly interface featuring six straightforward keys—ON/OFF, CAL, MODE, SAMPLE, PRINT, REZERO—and a large, front-mounted spirit level with LED illumination for easy leveling. The balance's flexible communication capabilities, including RS-232C and USB interfaces, support seamless data management. All these features are housed in a design that allows for easy cleaning and maintenance of the weighing pan and dust plate. The A&D Weighing Apollo GF-224A Analytical Balance is backed by a 5-year warranty, assuring long-term reliability and support.

balances
A balance is a tool used to measure the weight of an object. Balances are used in a variety of applications, including scientific research, manufacturing, and commerce. Balances typically consist of two plates or pans suspended from a fulcrum. The object to be weighed is placed on one pan, while weights are placed on the other pan until the two sides are balanced. Balances can be used to measure mass, weight, and volume.
Scales
Scales scientific equipment is a category of laboratory equipment used to measure and weigh a variety of substances. This type of equipment is used in a variety of scientific fields, including chemistry, biology, and physics. Common types of scales scientific equipment include analytical balances, precision balances, and microbalances. These instruments are used to measure the mass of a substance, as well as to measure the volume of a liquid. Scales scientific equipment is also used to measure the density of a substance, as well as to measure the temperature of a substance.
