Descriptions :

The Antifreeze/Battery/cleaning fluids Refractometer is designed for testing for concentration of the battery fluids, antifreeze liquid and cleaning fluids. With the indication of the temperature you may know at which temperature the fluid will be frozen for both propylene glycol and ethylene glycol. It can also be used for checking the strength of electrolyte solution batteries.

The model REF413 has °C unit system. With the indication of the temperature we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. And It can also be used for checking the strength of electrolyte solution batteries. The REF413 has Automatic Temperature Compensation System.

How to Calibrate the refractometer ?

Instructions
1.Select the calibration liquid. Some models use a special calibration liquid while others use distilled water. Lift the daylight plate and place 2 to 3 drops of the calibration liquid on the prism assembly.

2.Close the daylight plate and allow the calibration liquid to spread across the prism without any dry spots. Wait 30 seconds so the sample can reach the temperature of the refractometer.

3.Point the refractometer toward a natural light source since artificial lighting can cause the reading to be inaccurate. Look into the eyepiece and adjust it so that the scale is in focus. Adjust the calibration screw so that the refractometer reads exactly zero.

4.Clean the daylight plate and the main prism assembly with a soft, damp cloth.
