2 Holes Grease Drop Point Tester Heating 800W Oil Bath Speed 120r/Min ASTM D566
Core Keywords: grease drop point tester, ASTM D566, ISO 2176, GB/T 4929, lubricating grease dropping point apparatus
Drop point is the lowest temperature at which lubricating grease transitions from semi-solid to liquid state under specified test conditions. It is a critical quality indicator that reflects grease heat resistance, base oil bleeding tendency and high-temperature stability.
A drop point test helps buyers select suitable grease for high-temperature mechanical applications, avoid premature softening, oil leakage and equipment failure under continuous operating heat.
Target Application: Drop point testing of lithium, calcium, complex soap and synthetic lubricating greases in petroleum labs, grease factories and quality inspection institutes.
The SD4929A is a bench-top oil-bath drop point tester manufactured in compliance with GB/T 4929, ISO 2176, ASTM D566 and TP31. It adopts a double-hole test unit, continuous solid-state temperature regulation and built-in mixing motor, delivering stable heating and repeatable drop point results for laboratory grease analysis.
