ASTM D1881 Foaming Tendencies Test Apparatus for Engine Coolants

Introduction

This ASTM D1881 Foaming Tendencies Test Apparatus uses glassware to determine foam tendency of engine coolants under certain temperature and ventilation.It adopts high temperature resistant glass tank as heating bath,which makes sure the uniform temperature of working environment.

This Engine Coolants Foaming Tendencies Test Apparatus is equipped with special airflow control system,and it can reduce the error caused by manual intervention.
