Description: This refractometer is a portable, precision optical instrument. It's a convenient tool to check your automotive coolant and protect your car engine. No battery needed. It features high-quality optics with ultra smooth focusing. Its main body is made of aluminum alloy. The internal optical lens with high refractive index make up the precision optical system. The instrument is resistant to abrasion and corrosion resistance. Can be measured acidic and alkaline and other general corrosive liquid. Notice: 1.Accurate measurement based on good calibration, please calibrate the refractometer before your first use. But you don't have to calibrate it frequently, once every a few months is OK. 3.When you put your sample to be tested on the daylight plate, make sure the liquid spreads across the entire surface of the prism without air bubbles or dry spots. 4.Clean the instrument with a soft cloth after each use, keep the refractometer dry and clean, which will keep the instrument accurate and durable. Do not put the entire instrument into water to wash, this may lead the refractometer to be foggy or rusty inside. 5.The instrument can be measured acidic and alkaline and other general corrosive liquid. But we do not recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. 6.Please do not loose any connection part, and don't dropping, colliding, shaking the instrument intensely. : Full 12 Month & Any Questions Will be Answered within 24 Hours. Function 1: Measuring freezing point temperture of ethylene glycol or propylene glycol based automobile antifreeze coolant. Scale range: ethylene glycol base: -84°F-32°F, propylene glycol based -60°F-32°F Function 2: Measuring concentration of ethylene glycol or propylene glycol based automobile antifreeze coolant. Scale Range: ethylene glycol base: 0-70% propylene glycol based 0-63% Function 3:Measuring specific gravity of battery acid and provide a quick reference of battery charge condition. Scale Range:1.100~1.400kg/l Features automatic temperature compensation: makes it more convenient to use in different temperature. Quick and easy: Just need 2-3 drops of solution and a few seconds, you can get accurate readings. And no battery needed.
