ASTM D1881 Foaming Tendencies of Engine Coolants Tester Bubble tendency analyzer

Foaming Tendencies of Engine Coolants Tester       ASTM D1881

 Product model: JF0066

Product Introduction

This instrument uses glassware to determine the foaming tendency of engine coolant under certain temperature and ventilation conditions controlled by the laboratory.

It uses a high temperature resistant glass cylinder as a heating bath to ensure a uniform temperature in the working environment. The instrument is equipped with a special air flow control system,

Reduce the error caused by manual intervention on the results.
