Refractometer vigneron content potential in Alcohol: 0-25% Sucre : 0-40% with ATC for The wine Brassage Brix for measure the content in Sucre in order to Produce A Better wine.

1. Settings technical mainly :

Range of measurement and scale minimum : Brix : 0-40 % Scale minimum : 0,2 %

Alcohol : 0-25%

With the function of compensation of temperature, it can surmonter the gap of data caused by the changes of temperature and make the data more precise

the eyepiece has summer improved, the glass of the objective is a glass optical to couronne heavy, not a glass ordinary, which has a more large clarity and reduces the fatigue of the observateur.

2. How use :

1) Align the prisme réfringent with the direction of the light and adjust the ring of angle dioptrique up to this that the line of marking either clearance ;

2) Adjust the benchmark : Before the measurement, prepare the solution etalon (water pure), the instrument and the liquid to test to the same temperature. Open the cover, then prenez 1 to 2 drops of gouttelettes standard on the prisme réfractif and press slightly on the cover with your hand for trace a line of demarcation between the light and the darkness. Turn the bolt of calibration for make coïncider the line of demarcation clear-foncee in the field of vision of the eyepiece with the line of reference (0 %) ;

Note : This instrument optical has summer adjusted in factory and can be used directly.

3) Open the cover, clean the surface of the prisme with a flanelle soft, prenez 1 to 2 drops of the solution to test on the prisme réfractif, covers the cover and press gently, and lisez the scale relative of the line of demarcation between clear and fonce, this is-to-say the solution creusee The value of concentration and the value of density of the liquid.

4) After the measurement, wipe directly the accessories on the surface of the prisme and the plate of cover with a flanelle wet and rangez-the correctly after drying.

Correction

the instrument must potentiometre the point zero before of measure. Prenez few drops of water distillee, place-the on the prisme of detection and turn the screw of adjustment of the zero for adjust the line of division on the position 0 % of the scale. Clean then the prisme of inspection and procédez to the inspection. Some models of instruments must be equipped of a solution standard to the place of water distillee when of the calibration.

Precautions

This instrument is a instrument optical of precision, the points following must be socket in count when of the use and of the maintenance :

1. You unscrew be prudent when of the use, the use strictly according the instructions and not loosen arbitrarily the pieces of connection of the instrument, not fall, enter in collision and interdire strictly the vibrations violentes.

2. After use, it is strictly interdit of the put directly in the water for the clean.It must be wipe with a cloth soft and clean.For the surface optical, it not must not be heurte or scratch.

3. the instrument must be stored in a place dry and non corrosion.
