Product Highlights Automatic Timing with Stop Function The instrument features a timed automatic stop function. When the 5-minute stirring cycle completes, the stirrer stops automatically. No need for manual timing or supervision. Precision Temperature Control Digital temperature controller maintains bath temperature within ±0.1°C. Accurate temperature is critical for demulsibility testing—even small deviations can affect results. Built-in Timing Alarm The alarm notifies you exactly when stirring stops and when standing periods (30 min or 60 min) are complete. This ensures accurate measurement of separation time and reduces operator error. Automatic Stirrer Lift The stirrer is equipped with an automatic lift switch for raising and lowering. No manual handling required, improving operator safety and test consistency. Adjustable Stirring Speed While standard test speed is 1500±15 r/min, the speed is adjustable. This feature is particularly valuable for R&D labs developing new formulations or testing unconventional fluids. Rotary 4-Station Design Unlike single-station testers, the DFYF-124 uses a rotary 4-hole turntable. You can prepare multiple samples and run them sequentially, maximizing lab efficiency without requiring multiple instruments.
