Professional freezing point tester wholesale and retail Beijing Hao Wei electronic instrument used for measuring various types of freezing liquid freezing point, freezing point and battery fluid is antifreeze proportion of dual-use tester for measuring the concentration of the battery and antifreeze solution designed; percentage may know freezing and windshield cleaning fluid freezing point of propylene glycol and ethylene glycol-based antifreeze system can also be used in the inspection and the use of lead-acid batteries proportion of state electrolysis, for the preparation, testing antifreeze, battery fluid to provide a very great convenience, this product is also suitable for all kinds of transport carriers and internal combustion engine cooling system; also be used for cooling water, refrigerant fluid with antifreeze and other car. Automobile manufacture, repair tools to detect standing. I. Features 1) Simple: The little liquid sample after the detection prism, you can read the value through the eyepiece. 2) Fast and efficient: 2 to 5 minutes to complete an analysis of water samples. 3) Reliable data: Depending on demand, can be customized in a variety of precision instruments. 4) Low cost analysis: no reagents or optional accessory. 5) small size, light weight, easy to carry. 6) Wide range of applications: for antifreeze, battery fluid, such as different samples can be analyzed in real time; 7) testers no training, just steps to the instructions. Second, the application for measuring the concentration of the main battery and antifreeze solution designed for the determination of ethylene glycol and ethylene glycol for freezing and windshield cleaning fluid freezing point based antifreeze system can also be used to check the lead-acid electrolysis share and use state within the battery, for the preparation, testing antifreeze, battery fluid to provide a great convenience. Automobile factories, auto repair, battery manufacturing, antifreeze and other professional preparation of the necessary tools.
