This is a PMC Dataplate model 721 hot plate / scientific stirrer. Power is 120 VAC and is tested as shown in the pictures.

Unit appears very nice with minor chipping? Of the ceramic around the bottom edges of the plate, but is in better shape than most I have seen. The following is from the manual. The DATAPLATE Hot Plate/Stirrer Series 720 is a programmable, general purpose, digital laboratory hot plate with stirrer.

The series includes the Model 721, single position stirrer, the Model 725, 5-position stirrer and the Model 729, 9-position stirrer. All functions on the Series 720 are settable from a digital front panel keyboard and display. Both the plate temperature and the stirrer speed are controllable to an accuracy never before offered in similar devices. Heater Either the plate surface temperature or the actual sample temperature may be set by the user.

A sensor in the plate is used to monitor surface temperature, or, alternatively, a temperature probe may be connected to the rear of the unit and inserted into the sample. An optional 100 3-wire, Platinum RTD temperature probe is available with a 6 stainless steel or glass jacket. When a temperature is set by the user, power is applied to the heater to precisely control the temperature at the plate surface or at the sample, as directed. An optional "ramp value" may be entered into the unit which causes the temperature to approach the target value at a controlled rate of temperature change. Temperature may be displayed in either °C or °F as set by a rear panel switch.

Stirrer The stirrer is a motor-driven magnet which, in the model 721, revolves directly under the center of the heater plate. The Model 725 has five motors with one placed in the center and one at each corner of the plate. The Model 729 has nine stirrer motors placed in three rows of three each.

It is common practice, when heating solutions, to spin a "stir bar" (Teflon-coated bar magnet) which is placed in the solution. This assures a more uniform temperature throughout the solution. The stirrer speed is set from the front panel keyboard. Timer All Series 720 units have built-in timers. The timer counts down in hours, minutes and seconds, sounding an alarm when it reaches zero. The timer may be used independently of the heater and stirrer or may be used in conjunction with the "Auto Off" function to shut off both the heater and stirrer after a preset length of time. The front panel of the DATAPLATE 720 Series has a digital keyboard display for monitoring and controlling hot plate functions.

The ON/Off switch is located on the right side of the front panel. When the unit is on, the display located on the left side of the unit will be lighted.

The display is a four-digit vacuum fluorescent type with a colon between the middle two digits. It is used to display the temperature, stirrer speed and timer value. The keyboard has 12 pushbutton keys and is used both for selecting the display function and for entering numerical values for the temperature, stirrer speed and timer. Rear Panel The AC power connector jack and fuse holder combination is located on the left side of the rear panel. The °C/°F display switch is to its right, followed by the l/O port, the remote temperature sensor jack and the four temperature calibration pots on the right side of the panel. The AC power jack is a three-prong, male plug combined with a dual, snap-in fuse holder. The type of fuse used in the unit is embossed on the front of the holder. Both neutral and high lines are fused. The °C/°F display is controlled by the position of the slide switch to the right of the power jack.

The front panel display will reflect the temperature units by displaying a °C or °F after the temperature readout. The I/O port will, when used with the proper cable, allow for remote control of the unit by the Model 740 multicontroller. The remote temperature sensor input is a 5-pin DIN jack which is used with a three-wire, Platinum RTD temperature probe.

The two calibration potentiometers on the left are for calibrating the remote temperature sensor, the two on the right are for calibrating the hot plate temperature readout.
