Purpose
PT-D892-12579 Lubricating Oils Foaming Characteristics Tester is designed and made as per GB/T12579 "Test Methods for Foaming Characteristics of Lubricating Oils" and ASTM D 892. It is suitable to determine foaming characteristics of lubricating oils, so that to evaluate the foaming tendency and foaming stability of lubricating oils.
 
Main technical features
1. The instrument adopts all-in-one structure. It includes three parts: low temperature test part and it's control, high temperature test part and it's control, a portable cooler for low temperature test part.
2. The temperature controller has parameters modifying function. If there is bias between showing temperature and testing temperature,it ca be corrected by this function.
3. The instrument equips an automatic timing alarm.
