Key features of CY 323C
320 g × 0.001 g
Milligram readability with a 320 g capacity, one step above the analytical range.
Motorised internal calibration
Built-in weights calibrate at a keypress; PSAC repeats it when temperature or time changes.
Draft shield with IP54
Three-side-opening glass shield; Aczet states IP54 protection against dust and water splashes for the series.
11 built-in applications
Counting, percentage, formulation, pipette check, check weighing, density, statistics and more.
GLP-ready records
Built-in GLP documentation and RS 232C interface (USB optional) for traceable results.
Key advantages of CY 323C
Less time with test weights
PSAC runs the internal calibration for you when conditions change.
Light samples are fine
Typical minimum weight is 1 g by the USP 0.1% criterion and 0.1 g at U = 1%.
Easy to keep clean
The draft shield parts can be dismantled and assembled again without tools.
Overload protection
A capacity tracker on the display helps protect the weighing cell.
Weigh what does not fit the pan
A below-balance hook is provided for oversized, magnetic or hot and cold items.
About CY 323C
The Aczet CY 323C Precision Balance weighs up to 320 g with a readability of 0.001 g (1 mg). It is the balance many labs choose when they search for a "320 g 0.001 g precision balance" and need a milligram result on samples that are too heavy for an analytical balance. The letter C in the name stands for the motorised internal calibration of the Professional Level CY-C series.
Calibration that looks after itself
Built-in motorised weights calibrate the balance at a keypress. The Perfect Self Auto Calibration (PSAC) function repeats the internal calibration automatically when the temperature changes or after a set time, so readings stay reliable through the working day.
Specifications that matter at the bench
Capacity 320 g, readability 0.001 g, repeatability 0.001 g, linearity ± 0.002 g (Aczet datasheet).
Minimum load 0.02 g, typical USP minimum weight 1 g (0.1%) and 0.1 g at U = 1%.
Pan 128 × 128 mm, response time 2 to 3 seconds, tare range up to the full capacity.
Built for daily laboratory work
The balance has a large backlit LCD, a spacious glass draft shield that opens on three sides and an IP54 protection class against dust and water splashes, as stated by Aczet for the series. The shield parts can be taken apart for cleaning. A capacity tracker on the display warns about overloads, a monitoring function watches ambient conditions, and a hook allows below-balance weighing. Eleven built-in applications include piece counting, percentage weighing, formulation, pipette check, check weighing, totalization, density and statistics. A built-in GLP documentation function and the RS 232C interface (USB optional) support ISO / GLP / GMP records.
Who it suits
Aczet names food, pharma, chemical, cosmetic, polymer, cement and testing laboratories as typical users. If you need 220 g, 510 g or another capacity in the same series, tell our team about your application and we will confirm the right model for you.

Frequently asked questions: CY 323C
The CY 323C weighs up to 320 g with a readability of 0.001 g (1 mg). Repeatability is 0.001 g and linearity is ± 0.002 g according to the Aczet datasheet.
Yes. The C in CY 323C means motorised internal calibration with built-in weights. PSAC repeats the calibration automatically when temperature or time changes.
Both are 320 g × 0.001 g precision balances. The CY 323C has motorised internal calibration and is in the Professional Level series; the CY 323 uses external calibration with a test weight.
The price depends on the configuration, accessories and GST. Send us an enquiry with the model name and we will share a quotation.
