*Clean, accurate, and automated – metal-bath design meets SH/T 0722*
Foaming at high temperatures can compromise lubricant film strength, leading to inadequate lubrication, overheating, and equipment damage. The DFYF-114G Tester is specifically designed to evaluate the foaming tendency and stability of lubricating oils at elevated temperatures (150 °C) in strict accordance with SH/T 0722. Featuring an innovative integrated metal-bath instead of traditional oil baths, a 7-inch color touchscreen, and automated flow control, this instrument brings convenience, accuracy, and repeatability to your laboratory.

Key Features & Advantages
✔ Strictly complies with SH/T 0722
Ensures test results meet industry requirements for high-temperature foam characteristics of lubricating oils.
✔ Innovative metal-bath design – no more messy oil baths
The integrated metal-bath replaces traditional oil baths. It is clean, easy to maintain, and eliminates the risk of oil spillage or fume generation. The compact, elegant appearance saves bench space and simplifies operation.
✔ 7-inch color touchscreen – intuitive and fast
All test parameters are set via the user-friendly touchscreen interface. No complex button sequences – just tap and start.
✔ Precise temperature control at 150 °C
Maintains 150 °C ± 0.1 °C with high stability, critical for accurate foam testing under demanding conditions.
✔ Standard flow meter with needle valve
Flow rate adjustable from 0 to 94 mL/min – easily set the required air flow for the test.
✔ Fully automated test sequence
Connect the apparatus, tap “start” on the screen
The instrument automatically activates the air supply and adjusts flow rate
At the end of the test, air flow stops automatically – no manual intervention required
✔ Four independent test stations
Accommodates up to four samples simultaneously, greatly improving laboratory throughput.
