REFRACTOMETER ATC MANUAL REFRACTOMETER SALTING METER MEASURING INSTRUMENT SEAWATER REFRACTOMETER ATC REFRACTOMETER Refractometers operate on the principle that the refractive indexes of a liquid change with the change in concentration. It is portable, easy, fast and battery free, easier and more accurate than traditional areometers, cheaper than digital meter. It is an ideal tool for adults and young, for home or professional use. The internal optical lens with high refractive index creates a precise optical system. Ma simple design, ale is very practical to use, which ensures a good user experience. LIST OF PACKAGES 1 x refractometer 1 x Wipe Cloth 1x straw 1 x manual in English 1 x screwdriver 1 x pakowania MANUAL REFRACTOMETER The built-in automatic temperature compensation function ensures that the reading is always accurate and does not ma the need to deliberately control the temperature of the liquid, just make sure that ma ona room temperature (in the range of 0-25 ℃). Just take a few drops of liquids on the prisms and hold the refractometer pod light, then look through the eyepiece for a reading. SALTING METER Color: as shown.
