K19400 High Temperature Dropping Point Apparatus


Test Method
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

• Six-sample testing capability

• Microprocessor programmable high accuracy temperature control


K19400 High Temperature Dropping Point Apparatus
Tests dropping points of lubricating greases at temperatures of up to 400C (752F). 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 0.5C stability. Insulated cabinet has a chemical resistant polyurethane finish.
