Designed to determine the physical properties of liquids by measuring the refractive index at the boundary of media.
Thanks to this, it is possible to determine:
battery level
freezing point of fluids based on Propylene glycol or ethanol
washer fluid freezing point
улей>
for use in cars, trucks and buses.
Included:
sampling pipette
cleaning cloth
sturdy box
Measure instruction:
открыть пластиковую крышку для доступа к призме
using a pipette, place a few drops of the solution on the PRISM ' s surface,
close the lid in such a way as evenly distribute the liquid around,
wait about 30 seconds to make the temperature of the sample equal to the temperature of the instrument,
point the refractometer towards the light source and look through the viewfinder,
read the value on the appropriate scale on the border of the white and blue area (light / shadow border).Ли>
By adjusting the sharpness, when the measurement image is blurry and impossible to read, adjust the focus using the knob located behind the lens.
To calibrate the refractometer before use:
open the PRISM cover,
Using the pipette provided, add 3-4 drops of water
close the cover and press it so that the liquid spreads evenly over the prism without air bubbles,
point the refractometer towards the light-bulb / sun / window
Using a отвертка, adjust the calibration screw until the boundary line between the white and blue fields (i.e. light-shadow line) will align with the WATERLINE line indicated on the scale on the lens.Ли>
