For Lab Professionals who Create the Distinguished Achievement

ViBRA LF series provides everything lab professionals need for daily weighing works. With 0.01mg readability up to 130g weighing range and 0.1mg up to 220g, the user can experience reliable measurement operation in wide range of weighing applications ... simple weight measurement, percentage weighing, density measurement, etc… In every scene, ViBRA LF series promises excellent weighing performance which leads lab professionals to distinguished achievements.

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.

α-Check

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. He/she can change response speed in three levels just with out-touch of SET key.

Se-CAL

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 to easily output to printer and PC.

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.
