Precision Balance – Aczet – CY Series External Cal.

Key Features & Major Highlights

1. Mono‑Tech Weigh Sensor

   • Uses Aczet’s high‑end Mono‑Tech single‑cell weighing technology, providing good stability, precision, and long-term durability.

2. External Calibration

   • Requires manual calibration using an external certified weight.

   • Helps maintain traceable accuracy (useful in GLP, GMP, USP environments).

3. Overload Protection / Capacity Tracker

   • A “capacity tracker” is built into the display, which shows how much of the maximum capacity is being used — prevents overloading the weigh cell.

4. Built Quality & Construction

   • Durable housing (ABS) plus a stainless-steel weighing pan for corrosion resistance and easy cleaning.

   • Adjustable feet + circular level bubble for precise leveling.

   • Some models have IP54 protection (dust + splash resistance).

5. Display & User Interface

   • High‑contrast, backlit LCD display with large (15 mm) digits — very easy to read.

   • Built‑in real-time clock for GLP-compliant timestamping.

6. Weighing Modes / Applications

   • Supports many built-in application modes:

     • Piece counting (PCS)

     • Percentage weighing (%)

     • Check weighing

     • Below‑balance (use of a hook) weighing

     • Density determination (for solid/liquid)

     • Formulation and statistical calculations

7. Connectivity

   • Standard RS-232 interface for data transfer.

   • Optional USB interface for easier data export / connection to modern PCs.

   • Communicates with Windows applications (like Excel) directly.

8. Power / Energy Features

   • External DC adaptor (100–240 V) ensures compatibility.

   • Has auto power-off for energy saving.

9. Environmental Monitoring

   • Monitors ambient conditions (temperature, etc.) to maintain weighing accuracy.

10. GLP / GMP Compliance

    • With timestamping, data logging, and stable calibration, the balance supports GLP / GMP documentation.

11. Anti‑Theft & Safety

    • Includes anti-theft lock feature in some models.

    • Protective cover is standard.

12. Below-Balance Hook

    • Some models support a hook for weighing items suspended below the balance.

Advantages (Pros)

• Very High Precision: Thanks to Mono-Tech sensor, you get reliable measurements with low drift and good repeatability.

• Flexible Calibration: External calibration gives you control over when and how calibration is done, which helps maintain traceability.

• Versatility: Multiple weighing modes (density, piece counting, % weighing, etc.) make it useful for a wide set of lab tasks.

• Durability: Strong build, stainless steel pan, IP54 (in some) — good for regular lab or industrial use.

• Good Data Handling: RS-232 and optional USB make it easy to export weighing data to a PC or printer.

• Regulatory Ready: GLP / GMP compliance features (timestamp, capacity tracking) make it suitable for regulated labs.

• User-Friendly Display: Large, clear LCD with backlight makes readings very easy, even in less-than-ideal lighting.

• Safety Features: Overload protection, leveling feet, and optional anti-theft make the instrument safer to use.

Disadvantages (Cons)

• Requires External Weights: Since calibration is external, you must have certified weights, which adds cost and effort.

• Manual Calibration: Not automatic — user needs to perform calibration regularly.

• Sensitive to Environment: To maintain accuracy, you need a stable, draft-free, vibration-free location.

• Power Dependence: Needs a stable power supply; not ideal for fully portable or battery-powered use.

• Learning Curve: Because of multiple modes and calibration steps, users will need some training.

• Maintenance: Needs periodic cleaning of the pan and checks on calibration; incorrect handling can cause drift.
