Brookfield Temperature Controller, Model 75 - Manual (Page 3)

Brookfield Engineering Labs., Inc. Page 3 Manual No. M/98-205-A0100
I. INTRODUCTION
The Model 75 Temperature Controller is part of the Brookfield Thermosel accessory to allow for
viscosity measurements at elevated temperatures. The unit includes a solid state proportional
temperature controller, a means for entering the desired temperature setpoint and appropriate
status indicators.
The front panel is used to display and enter setpoint temperatures. The front panel also presents
the status of the system (e.g. the current temperature of the Thermosel and any error messages).
A list of the parts shipped with the Model 75 Controller is provided below. If any parts are miss-
ing or damaged, please contact Brookfield or your local authorized representative immediately.
