Aczet CY 224 Analytical Balance 220 g × 0.1 mg

The Aczet CY 224 is an analytical balance with a 220 g capacity and 0.1 mg readability, using external calibration with a test weight. It has a 90 mm pan, a backlit LCD, several built-in weighing applications, RS 232C output (USB optional) and a glass draft shield. It is the standard-series counterpart of the internally calibrated CY 224C.

Overview

The Aczet CY 224 Analytical Balance is a 220 g × 0.1 mg (0.0001 g) balance for routine analytical weighing. In Aczet's range the plain CY 224 is the standard-series model, which means it is calibrated externally with a certified test weight, while the CY 224C adds motorised internal calibration.

Why labs choose the CY 224

A 220 g capacity with 0.1 mg readability covers most day-to-day work in quality control, teaching and research labs: preparing standards, weighing reagents and checking batches. External calibration keeps the balance simple and usually keeps the purchase cost lower than an internal-calibration model, as long as a calibration weight is at hand (Aczet lists E1, E2 and F1 test weights as accessories) and calibration is done on your lab's schedule.

Specifications (Aczet standard datasheet)

Capacity 220 g, readability 0.1 mg, repeatability 0.1 mg, linearity ± 0.2 mg.
Typical minimum weight 160 mg (USP 0.1%) and 16 mg (U = 1%).
Pan diameter 90 mm, response time 2 to 3 seconds, operating temperature 18 to 30 °C.

Operation and records

An alphanumeric backlit LCD shows the result clearly. Application modes include piece counting, percentage weighing, animal / dynamic weighing, check weighing, automatic density determination, formulation and an automatic statistic calculator, with many units from grams and milligrams to carats and ounces. The RS 232C interface (USB optional, with Windows direct communication) connects a printer or computer, and Aczet lists ISO, GLP / GMP and USP compliance.

CY 224 or CY 224C?

Choose the CY 224 when external calibration is acceptable. If the balance is used by several people, in a room with temperature swings or under a strict calibration routine, the internal-calibration CY 224C may suit better. Our team can help you compare the two and confirm the right model.

Placement and accessories

For stable readings put the balance on a firm, level bench away from draughts, direct sunlight and vibration. Aczet lists an anti-vibration pad, an anti-thief lock, a density kit, test weights, a remote display and a 21 CFR Part 11 PC software among its accessories for this series; ask us which ones suit your lab.

Key features

220 g × 0.1 mg Standard analytical range with 0.1 mg readability and 220 g capacity.
External calibration Calibrate with a certified test weight; a simple, cost-effective setup.
Backlit LCD and 90 mm pan Easy-to-read display and a pan sized for routine analytical weighing.
Multiple weighing modes Counting, percentage, check weighing, density, formulation and statistics.
RS 232C and optional USB Send results to a printer or PC for GLP / GMP records.

Key advantages

Cost-effective choice The standard series has no motorised internal weights, so it is the simpler route to 0.1 mg weighing.
Same performance figures Datasheet repeatability 0.1 mg and linearity ± 0.2 mg, the same as the CY 224C.
Small samples Typical minimum weight 160 mg (USP 0.1%) and 16 mg at U = 1%.
Many units Grams, milligrams, carats, ounces and other units are built in.
Accessories available Density kit, test weights, printer, anti-vibration pad and more are listed by Aczet.
