– Designed to SH/T0085 Standard, Simultaneously Evaluating Coolant Corrosion on Six Types of Metals
Engine coolant can corrode various metals in the cooling system over long-term use, directly affecting engine life. The DFYF-173 Corrosion Tester is designed and manufactured in strict accordance with industry standard SH/T0085, suitable for determining the corrosion degree of engine coolants on a typical metal coupon bundle (including copper, aluminum, cast iron, steel, brass, solder, etc.). It is a core instrument for evaluating the anti-corrosion performance of coolants.

Key Features
◆ Split-Type Safety Design
The instrument consists of a control section and a test section. The split design enhances electrical safety and operational convenience.
Control section: integrates temperature control, timer, circulating water pump, and switch assembly
Test section: includes flow meter and water bath
◆ High-Precision Digital Temperature Control
A digital temperature controller provides accurate bath temperature control with an accuracy of ±0.1℃, ensuring stable test conditions.
◆ Three Integrated Systems
The instrument comprises an air circuit, a water circuit, and a heating bath:
Air circuit: composed of an air pump and a gas flow meter, providing a stable flow rate of 100 ± 10 ml/min
Water circuit: a circulating pump ensures uniform medium flow
Heating bath: consists of a transparent glass bath, temperature controller, and stirrer
◆ Transparent Glass Bath
The test bath is made of transparent glass – aesthetically pleasing and allowing easy observation of metal coupon changes during the test, making operation more intuitive.
◆ High-Throughput Parallel Testing
Up to six tests can be run simultaneously, significantly reducing manual repetition and saving time – ideal for batch sample testing.
Applications
This tester is suitable for engine coolant manufacturers for outgoing corrosion testing, third-party testing laboratories, automotive parts laboratories, and research institutes, providing reliable data for coolant formulation screening, quality assessment, and standard compliance verification.
