Introduction and Safety Precautions
The Benchmark C Heated Laboratory Centrifuge is intended for use in Class I, Division 2 testing
laboratories and refineries. It operates on 120/240VAC and comes completely assembled and ready
for installation. Also included are a set of tubes, cushions, shields and collars (four each). Unpacking
and lifting the centrifuge should always be done by at least two people. Retain the custom packaging
materials for future shipping or storage.
The unit is equipped with a programmable digital temperature controller with an LCD display. The
RTD meter, or temperature controller, is preset at 140°F (60°C). There is an encoder driven
tachometer with an LCD display of the actual motor speed. Variable speed motor control is included
with a preprogrammed acceleration/deceleration ramp to ensure smooth operation.
The programmable countdown timer is integrated with the motor controller – the countdown begins
only upon reaching the designated speed for the test. Both the timer and the temperature controller
settings are adjustable.
This centrifuge is designed to optimize operator safety and includes an automatic-locking door.
Carefully following safety guidelines (i.e. OSHA) and knowing the limits of this unit will help prevent
accidents.
