Semi Micro Balance
CY-C Professional Semi-Micro Balance
The Aczet CY-C Series Professional Semi-Micro Balances give you 0.01 mg readability for weighing small samples in the laboratory. Five models cover 60 g to 250 g: the single-range CY 205C (210 g) and the dual-range CY 165C, CY 265C, CY 285C and CY 255C, which switch between 0.01 mg and 0.1 mg. A backlit LCD with 15 mm digits, motorised internal calibration with automatic recalibration, a grid pan under a glass draft shield and a built-in clock for GLP records make them practical for pharma, chemical, food and research labs.

Key features of CY-C Professional Semi-Micro
0.01 mg readability, five models
The CY 205C, CY 165C, CY 265C, CY 285C and CY 255C cover 60 g to 250 g, all reading to 0.01 mg.
Single or dual range
Choose the single-range CY 205C, or a dual-range model that gives 0.01 mg and 0.1 mg readability in two ranges.
Automatic internal calibration
Motorised built-in weights plus PSAC recalibrate on a temperature change or after a set time.
Clear backlit display
A high-contrast backlit LCD with 15 mm digits is easy to read in any room lighting, with push-button operation.
GLP-ready records
A built-in clock, RS 232C output (USB optional) and an automatic statistics calculator support traceable documentation.
Key advantages of CY-C Professional Semi-Micro
Right capacity, same readability
Pick the capacity you need from 60 g to 250 g and keep 0.01 mg readability.
Overload awareness
The built-in capacity tracker on the display shows possible overloads before they reach the weighing cell.
Fewer manual calibrations
PSAC repeats the internal calibration when temperature changes or a defined time has passed.
Many weighing tasks in one balance
Counting, percentage, check weighing, density determination, formulation and statistics are built in.
Weigh below the balance
A below-weighing hook lets you weigh samples that cannot sit on the pan.
About CY-C Professional Semi-Micro
The Aczet CY-C Series Professional Semi-Micro Balance range is built for routine laboratory weighing where a readability of 0.01 mg (10 µg) is needed. Aczet describes a semi-micro balance as one that measures small sample sizes with 0.01 mg readability and a capacity of up to about 220 g, and offers it as a single-range balance with one fixed range or as a dual-range balance with two ranges and two sensitivities. The CY-C Series covers both types.
Five models, two types
Single range: CY 205C, 210 g capacity, 0.01 mg readability.
Dual range: CY 165C (100 / 160 g), CY 265C (60 / 220 g), CY 285C (80 / 220 g) and CY 255C (100 / 250 g), each reading 0.01 mg and 0.1 mg.
All five models share a minimum load of 1 mg, a stainless steel grid pan (80 mm on the dual-range models, 91 mm on the CY 205C) under a glass draft shield, and a response time of 2 to 4 seconds (CY 205C) or 2 to 8 seconds (dual-range models).
Weighing technology
Aczet calls the weigh sensor its Mono-Tech technology. Fully automatic motorised built-in weights provide internal calibration, and the Perfect Self Auto Calibration (PSAC) function repeats the calibration when the ambient temperature changes by a set value or after a defined time interval. A capacity tracker on the display helps you spot possible overloads, and a below-balance weighing hook lets you weigh under the balance.
Operation and records
The high-contrast backlit LCD has 15 mm digits that stay easy to read under any room lighting, and operation is by push buttons on the front panel. The balance supports piece counting, percentage weighing, animal / dynamic weighing, check weighing, automatic density determination, formulation and an automatic statistics calculator, and many units from grams and milligrams to carats and ounces. The built-in clock lets documents carry a time stamp for ISO / GLP / GMP record keeping, an RS 232C interface is provided (USB optional, with Windows direct communication), and an automatic shut-off helps save power.

Frequently asked questions: CY-C Professional Semi-Micro
Aczet lists five models: the single-range CY 205C (210 g) and the dual-range CY 165C (100 / 160 g), CY 265C (60 / 220 g), CY 285C (80 / 220 g) and CY 255C (100 / 250 g). All read to 0.01 mg.
A single-range balance has one fixed range and one readability. A dual-range balance has two ranges with two readabilities. In the CY-C series the dual-range models read 0.01 mg and 0.1 mg. The datasheet prints the capacity, repeatability and linearity as two values for these models.
The minimum load is 1 mg on every model. Aczet gives a typical minimum sample weight according to USP Chapter 41 of 20 mg for the CY 205C, CY 165C, CY 265C and CY 285C, and 30 mg for the CY 255C.
The dual-range models (CY 165C, CY 265C, CY 285C and CY 255C) have an 80 mm diameter grid pan and the CY 205C has a 91 mm diameter grid pan. The pan sits under a glass draft shield.
It has motorised internal calibration with built-in weights. The Perfect Self Auto Calibration (PSAC) function repeats the calibration when the ambient temperature changes by a set value or after a defined time interval.
The balance has an RS 232C interface, with USB (Windows direct communication) as an option. Aczet also lists a dot-matrix data printer as an accessory on its product page.
No. The CY-C Series has an alphanumeric backlit LCD with a push-button keypad. Aczet offers a separate touch-screen semi-micro balance.
Aczet gives the operating temperature as 15 to 35 °C for the dual-range models and 5 to 40 °C for the CY 205C. Place it on a stable bench; an anti-vibration weighing table is available as an accessory.
