2 Introduction

Hart Scientific’s Model 3125 Detachable Hot Plate is controlled by Hart Scien- tific’s 2200 controller and uses a precision platinum RTD as a sensor with a heater to control the temperature. The 3125 and 2200 are a matched set.

The controller display shows the temperature and also the set-point tempera- ture. The temperature may be set to any temperature within the range of 35°C to 400°C in 0.01°C or °F increments by using the buttons on the control panel. The controller’s multiple fault protection devices insure user and instrument safety and protection.

The Detachable Hot Plate (see Figure 1) consists of a controlled plate made of aluminum. A heater is attached to the bottom with an RTD temperature sensor used to control it. The housing consists of a top cover and a base, which serve as a clamp and strain relief point for the wiring. The Reference Well is avail- able for use with a 3/16-inch diameter probe, which may be used to check the plate temperature. This well is used to calibrate the system.
