TS-4 THERMAL MICROSCOPE STAGE
1.0 GENERAL DESCRIPTION
The TS-4 Thermal Microscope Stage consists of:
1.1 The STAGE, which is available in several configurations or may be custom designed.
Heat is supplied to or withdrawn from the specimen by means of a thermoelectric heat pump
attached to the upright portion of the controlled plate, Excess heat is conducted away by the cool-
ing water. When the stage is operated below room temperature, a curtain of cold air flows over the
specimen, minimizing condensation and improving temperature conformity.
1.2 The CONTROLLER will maintain stage temperature at any point within the stated range of
the stage, as follows:
TS-4 -20
o
to +60
o
C
TS-4ER -20
o
to +100
o
C
TS-4SPD -10
o
to +60

C
TS-4LPD -10
o
to +60

1.3 The DIGITAL THERMOMETER and TEMPERATURE PROBE.
A thermocouple microprobe is included with the equipment. If this probe is connected to the exter-
nal probe input, the controller can be used as an independent thermometer. Range is -100
o
to
+200
o
C and resolution is 1/10
o
.
1.4 OPTIONAL PUMP AND TANK UNIT
The Thermal Microscope Stage needs running water for operation. If access to a water tap is incon-
venient, a circulating pump with a 5 gallon tank is required. Our pump and tank unit, model PTU-3
can be used for this purpose.
