Product Description
The MRC Labs MGB series micro-balance is designed to achieve requirements of mass measurements with ultra-high precision internal calibration ensures measurement reliability and accuracy.
Applications
- Filling,
- Check weighing,
- Percentage,
- Statistics,
- Air buoyancy correction,
- Infrared sensors,
- GLP Procedures.
Features
- Eliminates the electrostatic influence during weighing process,
- Eliminates the temperature influence and separates from vibrations and shocks caused by users operating software,
- Internal automatic calibration,
- Consists of two major parts - an electronic system and a precise mechanical measurement system, kept in a separate closure,
- Made of glass and steel which eliminates the influence of electrostatics on the weighing process,
- Display of 5.7” touch.

Touchpad software controls
- Infrared proximity sensors,
- PRINT function,
- TARE function,
- Opening weighing chambers,
- Sensors’ sensitivity adjustment,
- Electronic level indicator,
- ALARM function,
- Graphic level indicator,
