Pramp Automation and Calibration
Category: Laboratory
Product: Laboratory Weighing Scale
Sub Product: Micro Balance
Our Micro Balances has been designed to meet high requirement for measuring small masses with high readability (d = 1 mg). They are equipped with graphic display/with user menu.
In order to guarantee proper accuracy of measurement, a half automatic system of external calibration with E 1 standard weight has been applied.
Micro balance consists of two balance components. One of them contains electronic modules & other precise mechanical measuring system. Such solution guarantees elimination of temperature changes influencing the indication micro balance.
Micro balances series CM ore offered with 4 capacity 2gm, 5gm, 11gm & 21gm (with readability 1 mg) balances are equipped with aesthetic, cylindrical shaped weighing chamber with glass draft shield. All elements of weighing chamber ore manufacture from glass or metal which minimize the influence of electro-static charges on weighing result. Micro Balance equipped with user friendly menu User has access to multiple functions & measuring units which allow for specification for working requirements.
