Product application: 

    The hand held refractometers' advantages are the structure very simple,shockproof,clear view,cheap and easy to operation and carry.The brix series are used for canned food,fruit juice making,fermentation,drinks,fruit and collecting honey,etc.The salinity series are used for aquaculture;aquarium and saline to prepare for the medical series are designed to measure the serum proteins and specific gravity of urine.The series of industria are used to measure the car battery fluid,antifreeze fluid,cleaning fluid,lubricating oil of machine and cutting fluid. 

    our all refractometers with Automatic temperature Compensation system. 

    Features: 

    For measuring the alcohol content of various liquors or the sugar concentrations in alcohol-related wines. 

    Lightweight and portable, the alcohol refractometer is simple designed and easy to operate. 

    Adjustable manual focus for easily focus and calibrate. 

    Specifications:

    Package Weight: 90g 

    Usage and procedure: 

    1.Make the prism(1)towards to the direction of the light souces and adjust he focus tube of eyepieces(4) til the scale line is clear 2-Seyibrgation, before test the standard solution (pure water) instrument and Sample must be at the same temperature for accurate results. 

    2.pen the daylight plate and place 1-2 drops of standard solution on the prism,and light press the daylight plate til get a lights and darkS boundary, turn the calibration Screw make the lights and darks.Boundary line of the field of view of eyepiece and datum line are coincide.(0%) 

    Note Before delivery,we have finished calibration and adjustment you can direct to use it. 

    3.Open the daylight plate.clean the surface of he prism with the soulint and place1-2 drops of sample on the prism,close the daylight plate and light press it,reading the lights and darks boundary relative graduations,this is the sample's concentretion. 

    4.after finished the measurement,direct to wipe of the depositbuilder on the prism and surface of he daylight plate with the damp int after dry proper keep it. 

       Notes and Maintenance:   

    1.After used it,don't wash it with the tap water directly.avoid the water entered the body.clean the instrument with the soft,damp cloth and ensure accurate measurement. 

    2.When use and storage,must be handling with care and careful maintenance.Avoid to scratch or collision damages on the surface of the optical components. 

    3.The prism and sample must be at the same temperature for accurate results. 

    4.The instruments should be kept in a dry.no dust,no corrosive gas environment and to avoid going mouldy of the optical parts' surface.
