Mu 126i

BEL Engineering introduce the new micro balance series “Mu” with 0,001mg resolution. Equipped with 5 inch color touch screen display that brings outstanding ease of use thanks also to the innovative wide double glass wind-shield that allows the user to weigh the samples with comfort. Advanced and efficient filtering algorithms will deliver quick and accurate results and many embedded functions to meet all the laboratory requirements. A bench ioniser is provided as standard to neutralize static electricity on charged samples.


Ioniser: integrated ioniser on the back of the balanceElectromagnetic Force RestorationElectromagnetic Force Restoration:
coil in a permanent magnet for the the most accurate weighings
Touchscreen DisplayTouchscreen Display:
technology, user friendly, easy to use and intuitive.
Internal database to store data and drying methods
Glp SetupGlp Setup:
Allows to store identification data of balance, project and user. Date and Time.
Date&TimeDate & Time:
Balance shows current date and time
allows to set recipes with name and tolerances for each ingredient. Automatic reproportioning
determines the title of a thread, measuring units: Tex, Td, Nm, Nc.
RS232Rs232 Data Interface:
to connect the balance to printer, PC, peripheral devices.
USBUSB interface:
it is possible to connect a usb pendrive
Measuring UnitsMeasuring Units:
Select the measuring unit that balance will use to display weight.
function to count identical items, reference quantities are selectable.
upper and lower limits can be set individually, for dosing and portioning.
Percentual WeighingPercentual Weighing:
function calculates the weight of a sample as a percentage from a reference weight (100%)
TotalizationTotalization Function:
measure cumulative weight of multiple items. Shows total and current weight
Animal WeighingAnimal Weighing:
accurate readings under unstable conditions such moving laboratory animals.
DensityDensity Determination:
function accurately determines density of a solid object or a liquid
Max LoadMax Load (Peak hold) function:
retains the peak value in a series of consecutive weights
StatisticsStatistics function:
shows Min, Max, Sum, Average, Standard deviation
user profile can be password protected
Multi LanguageMulti Language:
Several languages can be selected from the menu of the balance

  • 5 inch touch screen indicator that makes easy the operation and the navigation through the balance functions
  • Double wind shield for enhanced ventilation and temperature variation protection
  • External ioniser included with the balance to eliminate static charges
  • Automatic internal calibration
  • Wide range of embedded functions such us formulation, GLP, advance piece-counting etc.., 7 languages interface


A clear interface will show all the data also with real time bars


The double wind-shield is built with a metal evaporated metal coating to help to reduce at minimum static charges


A wide number of embedded functions come embedded with the balance


A ioniser is provided together with the balance. By blowing ions it neutralizes static electricity on charged samples like plastic parts, containers or films
