Product Description
Product Description
The HZ-3026C Coolant Foam Tendency Tester is a specialized instrument designed for evaluating the foam tendency of coolants. The system is composed of a control box that houses a flowmeter, a branch pipe, a temperature control meter, and a timer.
The instrument utilizes platinum resistance sensors and digital temperature regulators to maintain the bath temperature within the range of 88 °C ± 0.2 °C. This configuration ensures high control accuracy, an intuitive display, and good reliability throughout testing.
Additionally, the tester employs digital time relays for automatic timing and timed alarms, streamlining the testing process and ensuring consistent, repeatable results.
