*Reliable evaluation of coolant corrosivity per SH/T 0085*
Corrosion in engine cooling systems can lead to radiator blockage, water pump failure, and premature component replacement. The Engine Coolant Corrosion Tester (also known as Antifreeze Corrosion Analyzer) is designed and manufactured in strict accordance with SH/T 0085 – "Test Method for Corrosion of Engine Coolants". It is suitable for evaluating high‑boiling, low‑boiling engine coolants, their concentrates, and the corrosion inhibition performance of rust inhibitors in cooling system formulations.
Instrument Structure – Three Integrated ModulesThe tester consists of three functional systems:
| Module | Components | Function |
|---|---|---|
| Air circuit | Air pump + gas flow meter (adjustable) | Supplies controlled aeration to the test vessels |
| Water circuit | Circulation system | Manages fluid movement for consistent conditions |
| Heating bath | Transparent glass bath tank, temperature controller, stirrer | Provides stable, uniform heating for corrosion testing |
| Parameter | Value |
|---|---|
| Power supply | AC220V ±10%, 50Hz |
| Heating power | 2000W |
| Temperature control range | Ambient ~ 99.9°C |
| Temperature control accuracy | ±2°C |
| Number of test positions | 6 groups (six independent stations) |
✔ Standard compliant – SH/T 0085
Fully meets the requirements of the official Chinese standard for engine coolant corrosion testing, ensuring method consistency and result credibility.
✔ Integrated hot/cold bath design with observation window
The unit combines both heating and cooling capabilities in one structure. A transparent observation window is installed at the front of the high‑temperature bath, allowing operators to visually monitor sample conditions throughout the test without interrupting the process.
✔ Digital temperature control – precise and user‑friendly
A digital display temperature controller provides easy setting and accurate reading. The temperature control circuit maintains the high‑temperature bath at the required test temperature with a stability of ±2°C.
✔ Six independent test positions
Accommodates up to six samples simultaneously, significantly improving laboratory throughput and enabling parallel testing of different coolants or replicates.
✔ Transparent glass bath for clear visibility
The experimental bath is made of transparent glass, offering full visibility of the test specimens and liquid levels – a practical feature for observing corrosion development in real time.
✔ Adjustable aeration via air pump & flow meter
The air circuit includes a built‑in air pump and a gas flow meter with adjustable control, allowing precise regulation of air flow to the test cells as required by the standard.
