The high temperature dropping point test permits higher temperatures than the ASTM D566 method and uses a different heating procedure.
- Six-sample testing capability
- Microprocessor programmable high accuracy temperature control
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.
Tests dropping points of lubricating greases at temperatures of up to 400 °C. Dual LED displays provide actual and setpoint temperature values in °C/°F format.
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.
Microprocessor temperature control with digital readout and overtemperature safety cut-off maintains block temperature with ±0.5 °C stability. Insulated cabinet has a chemical resistant polyurethane finish.
Certifications: Conforms to the specifications of ASTM D2265, ASTM D4950.
Delivery information: Includes thermostatically controlled aluminum block oven and six complete dropping point assemblies consisting of test tube, grease cup, thermometer clamp, upper and lower bushings and bushing support ring, thermometer depth gauge, polished metal rod, cup support.
