Product Description
Features:
*Purpose:to Measure salt water or salinity of water.
*Ideal for testing and monitoring aquariums,fish tank, saltwater pool,seawater,marine monitoring,and labs or industry Use.
*Automatic Temperature Compensation makes it even easier to get fast and accurate results.
*No battery needed.
*Easy to calibrate and use :Place few drops of the liquid on the optical part of the refractometer, cover the prism , look throught the eyepiece against the light then you can the result value on the scale.
*Measures on two scales,Specific Gravity(D 20/20) & Salt Percent.
*Durable and built to last long.
*Cushioned with soft & comfortable non-slip rubber
*Easy to focus and calibrate.
Use Steps:
1.Align the"prism assembly"with light,adjust the"focus adjsutment"until you can see the scale clearly.
2.Calibration:
1）Accurate measurement depends on careful calibration,to calibrate the refractometer accurately,firstly you should make sure the ambient temperature is about 20℃，recommend you do the calibration in an air conditioned room in which the temperature is set on 20 ℃,you can use distilled water to calibrate.
2）Open the cover plate,then place 2-3 drops of distilled water on the prism,close the cover plate and make sure the water spreads across the prism without air bubbles or dry spots.
3）Wait for about 30s to let the reading to stabilize.Look into the eyepiece and turn the calibration screw with the screw driver until the reading is "0"
3.Clean the prism with soft cloth,and then place 2-3drops of the liquid sample to be tested on the prism,then close the cover plate and make sure the sample spreads across the prism without air bubbles or dry spots.
Wait for about 30s to let the reading to stabilize,Align the"prism assembly"with light source,look into the eyepiece and you can get the reading.
4.Clean the refractormeter with soft cloth and put it back into the box,keep the refractometer dry and clean,which can make the instrument accurate and durable.

The usual salinity of selected aqueous solutions:
Fresh water--------------<0.5 ppt
Brackish water--------------0.5 to 30 ppt
Saline water--------------30 to 50 ppt
Brine-------------->50 ppt
