With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol-based cooling systems. And they can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze liquids. There's also an additional scale for measuring the freezing point of windshield cleaning fluid.
How to Use:
1. Align the Cover Plate with light, adjust the Focus Adjustment until you see the scale clearly.
2. Calibration: Accurate Measurement depends on careful calibration. Please make sure the ambient temperature is about 68 °F, distilled water can be used to calibrate. Open the Cover plate. place 2-3 drops of the distilled water on the prism, then close the cover plate and make sure the water spread aross the prism without any air bubbles or dry spots. wait for about 30 seconds to let the reading to stabilize. Look into eyepiece and turn the calibration screw with the screw driver until the reading is "0"
3. Clean the prism with soft cloth, then place 2-3 drops of the liquid sample to be tested on the prism.then close the cover plate and make sure the water spread aross the prism without any air bubbles or dry spots. wait for about 30 seconds to let the reading to stabilize. Align the prism assembly with the light source. look into eyepiece and you can get the reading.
