Engine Coolant Antifreeze and Antirust Agent PH Value Tester

Engine Coolant Antifreeze and Antirust Agent PH Value Tester  

ASTM D1287 

Model: Jf0069

Product Introduction

The instrument is suitable for the detection of antifreeze, rust inhibitor and coolant, as well as used or unused water dilutions of these product concentrates, but not for the detection of solid rust inhibitors, when equipped with the corresponding ion selective electrode , can measure a variety of corresponding ion concentrations, can be used as a potentiometric titration measurement display instrument, the instrument has a temperature measurement function.
