Koehler Instrument K18300 / K18305 Single-Unit Roll Stability Tester

Product Description
Provides an indication of shear stability of lubricating greases by testing the change in worked penetrations after two hours in the roll stability tester.
Features and Benefits:
~ Maximum Temperature: 200°F (93°C)
~ Temperature Control Stability: ±2°F (±1°C)
~ Single, double and four-unit models
~ Microprocessor programmable high accuracy temperature control
~ High Temperature model available
Rotates steel test cylinders at 10 or 165rpm in a thermostatically controlled environment at temperatures of up to 200°F (93.3°C). Drive system is powered by a rugged ratio motor, and interchangeable drive chain sprockets are easily accessible for converting unit to either operating speed. Microprocessor PID control provides quick temperature stabilization without overshoot and is protected by an overtemperature control circuit that interrupts power should 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. A balanced cast aluminum fan and 1200W heater provide efficient, uniform heat distribution. A dial thermometer in the hinged cover displays chamber temperature. Heaters and drive chain mechanism are shielded for operator safety. Insulated steel cabinet and base are finished with a durable polyurethane enamel finish.

High Temperature Models - A high temperature model is also available that expands the temperature range to 320°F (160°C). Tests can be conducted using the high temperature model unit for time/temperature specifications beyond those listed in existing D1831.
