-50~0℃ 1℃ Antifreeze Liquid Freezing Point Handheld Refractometer Meter | |
Description: 100% brand new and high quality. Material: Aluminum Alloy + Plastic Suitable for motor vehicle antifreeze fluid, accumulator liquid, glass water Size: approx. 195(Diameter)*40mm/7.68(Diameter)*1.57inch Freezing point of antifreeze liquid: -50~0℃ 1℃ Proportion of electrolyte: 1.10~1.40Kg/L 0.01℃ Glass Water freezing point: -40~0℃ 5℃ Features: fast, accurate, light weight, small volume Advanced refraction technology, is derive from the theory of refrective index of different liquids. The body is made of solid aluminum alloy, superior rubber handle. High quality and accurate test result can easily calibrate via micro screwdriver. Automatic temperature compensation(ATC), easy to use and carry. Usage Introduction: Open the cover board, use soft cloth to clean test prism Fetch some determinand solution, place on the prism lens and close the cover board in order to avoid the bubble, and spread the solution on the prism surface. Focus on the light source or highlight place, observe the field via eyepiece, turn over the eyepiece to adjust the hand wheel. It made the blue and white line of field clear, the scale interval of boundry is the concentration of the solution. Package Includes: 1 Piece Handheld Refractometer 1 Piece Screwdriver 1 Piece Pipettes
Note: The product is designed to measure the freezing point of the battery solution and antifreeze. The results can be found that the freezing point of the antifreeze system based on ethylene glycol and propanediol and the freezing point of the front window glass cleaning liquid, can also be used to detect the specific gravity and use state of the electrolyte in the lead-acid battery, which provides a great convenience for the configuration, detection of antifreeze and electrolyte. With automatic temperature compensation, high precision, clear scale, export products. Tips: This section of the freezing point meter cannot measure the freezing point of methanol antifreeze and methanol glass water. Use note: Must be careful when using, strictly according to the instructions, not arbitrarily loose the connection part of the instrument, shall not fall, crash, strictly prohibit the occurrence of severe vibration, after use, strictly prohibited directly into the water cleaning, use soft cloth to wipe out, on the optical surface, should not touch the injury, the instrument should be placed in dry, non-corrosive gas place to keep, to avoid missing parts. |
