Features and Benefits

Cross-Over Sliding Windshield

VIBRA LF series is equipped with "cross-over sliding" windshield which enables the user to open the right-side door by left-side knob, vice versa. The user can handle the weighing sample with right hand while he/she operates the door with left hand. It makes weighing operation in lab routines less time-consuming


The laboratory / factory environment is changing every moment, and it affects the conditions of balance. In α-check system, VIBRA LF series gives diagnosis menu of its own conditions. Among check-items repeatability is the most fundamental parameter in laboratory balance, and the user can easily check it in this system

Easy RES

Stability and response speed should be correctly chosen according to environment and weighing objects. "Easy RES" offers the balance users very easy and simple way to change response speed in three levels just with out-touch of SET key


The regular calibration is highly important to assure the reliable weighing result. "Se-CAL" function in VIBRA LF series performs automatic calibration. When elapsed time or temperature shift leach to defined value. "Se-CAL" carries out the calibration fully automatically. The calibration record can be stored in the balance and output later on

Statistics for Lab and Manufacturing

Not only individual weighing result but also statistic values are frequently required in lab and manufacturing process. VIBRA LF series provides both of them. It has the function to automatically calculate the various statistical data, and easily output to printer

Bright LCD Back Light

With clear and bright back-lit LCD, the user can easily read the indication in the display. It reduces the reading errors. The brightness of back-lit can be adjusted in three levels


Other features and benefits:

  • Automatic Span Adjustment Function to keep maintain high accuracy. Advice CAL function to notify proper calibration timing.
  • Combination Door which opens to left/right/double door
  • Windshield designed for wide and space saving
  • Large and eye-friendlydisplay unit with back-light
  • Able to use as Counting Scale
  • Standard equipped USB Output
