ASTM D1177 Automatic Freezing Point of Engine Coolants Tester

Model:JF0090B

Introduction

This instrument is designed and manufactured in accordance with industry standards; it is suitable for determining the freezing point of engine coolant and its concentrate.

The instrument consists of four parts, including bath refrigeration system, bath heating system, motor stirring system, and color touch screen human-computer interaction system. The instrument bath uses alcohol as the refrigeration liquid, and adopts the compressor dual-machine refrigeration technology. The minimum temperature of the bath can reach -80 °C, which can cover the freezing point of all engine coolants.

The instrument comes with a 7-inch color touch screen, the screen can display the temperature curve of the sample, the temperature in the sample and the bath in real time, the user can set the expected freezing point in real time, modify the instrument time, self-check various parts of the system, etc., and can check the test results. Storage, using embedded system design, users can view historical data.
