Bright, White Back-light

Large LCD (16.5mm height) with bright & white back-light makes the weighing operation easy and comfortable even in the dark location.

Keep the Weighing Accuracy

The model with name AJ"H" has semi-automatic built-in calibration weight. You can easily calibrate the balance with built-in weight. It ensures the accurate and precise weighing operation.

Compact Housing, High Portability

The compact housing is one of the advantages of ViBRA AJ series. The space-saving design enables you to instal it even in small space.
Furthermore you can bring it everywhere you want with optional rechargeable battery.

Quick Response & Stable Indication

Quick response and stable indication are important feature in the precise weight measurement. The innovative tuning-fork sensor in ViBRA AJ series meets this demand and satisfies you.

Connection with Outside Devices

RS232C interface is installed as standard feature in every models of ViBRA AJ series. You can connect the balance to outside devices like PC.

What makes the tuning-fork sensor so precise?

The tuning-fork sensor measures force or mass by gauging changes in oscillation frequencey when a load is applied to a long, narrow vibrator, and it digitally outputs the readings.
Unlike load cell or electromagnetic systems, the tuning-fork sensor does not rely on material distortion, electromagnetic force, heavy power cunsumption, or A/D converters, so its inherent margin of error is extremely small, and its high precision can be maintained for a long time.
