    CWT-121/231/482-B-E

    Function:
    Constant weight tester for overall migration substance, nonvolatile and volatile substance, soluble and insoluble substance, moisture content.

     


    Principle:
    High-temperature baking; dehumidification cooling; constant temperature weighting. (Without water bath evaporating)

     

     

     

    Characteristics:
    ●Executing 3 processes automatically: baking, cooling, weighting;
    ●Accurate and efficient: constant weight error is less or equal to 3 mg through 2 rounds of baking; 12、23、42 specimen can be tested simultaneously;

    ●Safety:Heating in Aluminium plate, flame-proof and explosion-proof; Interrupting power when high temperature;
    ●Small-sized: baking room, cooling room, and weighting room are integrated into one room and the size is small;

    ●Patent moisture-proof, heat-proof, and erosion-proof to protect the analytic balance;

    ●All test parameters are set by the computer; the test procedure is executed automatically; 2 finish modes can be selected: set weight error and set time.

    ●Mettler-Toledo analytic balance module;
    ●Software: graphical, all-time, and all-element monitoring and multi-format reports;
    ●Optional: GMP “computerized system” function module;
    ●Optional: high efficient solvent recovery.
