KN-1177Z Automatic Freezing Point for Engine Coolant

Overview

  KN-1177Z Automatic Freezing Point for Engine Coolant conforms to ASTM D1177 Standard Test Method for Freezing Point of Aqueous Engine Coolants. This apparatus involves the determination of the time-temperature curve prior to freezing and the determination of the horizontal or flattened portion of the freezing curve. The freezing point is taken as the intersection of projections of the cooling curve and the freezing curve. If the solution supercools,

the freezing point is the maximum temperature reached after supercooling.

Features

1. 7-inch color LCD touch screen, stylish and beautiful. The English man-machine dialogue interface is clear and intuitive.

2. we use imported Danfoss compressor, which has fast refrigeration speed and stable performance.

3. unique motor-driven mixing technology, the mixing part is simple and beautiful, and the mixing frequency is adjustable.

4. we use imported high-precision temperature control module, equipped with high-level temperature sensor, which makes accurate temperature measurement with small error.

5. Collect the sample temperature in real time during the test, automatically display the temperature curve, and judge the inflection point according to the temperature curve change.

6. Equipped with 2 groups of test stations, which can carry out 2 groups of tests at the same time, it can also stir separately for 1 group of test

7. The host adopts microprocessor program control, automatic cooling during the test process, automatic collection of temperature, automatic display of temperature curve, automatic judgment of inflection point, automatic storage, automatic printing, and automatic shutdown at the end of the test.
