Feature

●Alcohol Concentration: Designed to measure alcohol, range 0-80%. Split lines (blue white) for easy counting and correct measurements
●No Power Required: Uses only natural light rays, no electronics or power supply
●Automatic Temperature Compensation: Automatic temperature compensation (10 - 30 degrees Celsius), screw calibration (calibration to 0, use in sites, no new calibration required when the environment changes in temperature), provides accurate measurements
●Convenient: The portable body is easy to use. Aluminum construction, lightweight and small volume, convenient to carry and use
●Multi-Purpose: It is widely used in scientific research, production and quality testing of ethanol concentrations in white sake


Description

Manual:
1. Open the cover and carefully insert the prism with soft cloth.
2. Take a few drops of the solution to test, place it on the prism, and gently close the cover to prevent air bubbles and allow the solution to spread to the surface of the prism.
3.Point the incoming plate of the device to a bright light source, observe scenes through the eyepiece and turn the eyepiece adjustment handle.
4. Clearly the blue-white partitions of the field of view, and the scale of the divided line will be the concentration of the solution.

Calibration:
Take a few drops of distilled water, drop into the detection prism, turn the zero adjustment screw to adjust the divider line to 0% of the scale, wipe the detection prism to detect it.

Notice:
1. When using, be careful not to loosen the connection of the fixture, collision or violent vibration, and follow the directions.
2. After use, it is strictly to put it into water directly and wipe it with a clean soft cloth to avoid impact and scratch the optical surface.
3. Please keep the equipment in dry place without corrosive gases.
4.Avoid lost spare parts
