The ASTM D2265 dropping point test permits higher temperatures than the ASTM D566 method and
uses a different heating procedure: the test cell is inserted in an aluminum block oven maintained at
a constant temperature that is higher than the expected dropping point of the sample. The sample
temperature then rises to the dropping point without operator control.Features and Benefits
- Conforms to ASTM D2265 and D4950 specifications
- Four-sample testing capability
- Microprocessor programmable high accuracy temperature control
APPARATUS :- Tests dropping points of lubricating greases at temperatures of up to 400°C
(752°F). Includes thermostatically controlled aluminum block oven and six complete dropping point
assemblies. Six-place oven has large viewing ports with fluorescent backlighting for excellent visibility.
Microprocessor PID control provides quick temperature stabilization without overshoot and the bath
is protected by an overtemperature control circuit that interrupts power should block temperature
exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature
values in °C/°F format. Communications software (RS232, etc.), ramp-to-set and other enhanced
features are available as extra cost options. Microprocessor temperature control with digital readout
and overtemperature safety cut-off maintains block temperature with ±0.5°C stability.
Dropping Point assemblies consisting of indented test tube and grease cup.
