Open the cover plate(2) and put one or two drops of distilled water on the cover plate and press it lightly, then adjust the correcting screw(3) to make the light/dark boundary coincide with the null line.
(Salinity/ATC Model should be adjusted at an environmental temperature of 20℃).
3.Open the cover plate(2), clean the surface of prism with a piece of soft cotton flannel,drop1~2 drops of the solution to be measured. Close the cover plate, press it lightly, then read the corresponding scale of light and dark boundary. The reading is the brix of measured solution.
4.After measurement, clean the surface of prism and cover plate with moist gauze. After drying, it should be stored carefully.
1.Adjustment for the null liquid and specimen should be in the same temperature. If the temperature varies greatly, the null point should be adjusted once per 30 minutes.
2.After usage, do not use water to wash the instrument, so as to avoid water entering into the pipe of the instrument.
3.This is a precision optical instrument. Handle it gently and take good care of it. Do not touch or scratch the optical surfaces.

4.If the consumers use the instrument in accordance with the mentioned method of usage, the optical performance should not change.
The reference of temperature is 20℃. In operation, the temperature compensation should be made according to the table. ATC is a refractometer provided with an Automatic Temperature Compensation function. It need not correct the temperature.
The retail price for this refractometer is over 100USD, but now we supply you in a wholesale price, because we are the specialized Chinese manufacturer of all kinds of refractometers, not a Player!
