Guarded Hot Plate with Data Acquisition
Product Code : EL-HAMTLE-10762
Guarded Hot Plate with Data Acquisition (code EL-HAMTLE-10762) is a bench-top unit for testing the thermal conductivity of non-metallic materials, in which two specimens are clamped between a central hot plate assembly with guard ring and two water-cooled cold plates inside an insulated test cabinet. The hot plate heater and the guard ring heater are each rated at 500 W with a control knob, and the standard listed for it is ASTM C177-04.

What Is the Guarded Hot Plate with Data Acquisition Used For?
In the guarded hot plate method, heat from a central hot plate flows through flat specimens to cooled plates on the far side, while a separately heated guard ring around the centre stops heat escaping sideways. With the heat flow kept one-dimensional, the measured power, the specimen thickness and area and the temperature difference across it give the thermal conductivity. The operator places two specimens of the material between the hot plates and the cold plates, clamps the cold plates for even pressure, connects the cooling water and sets the hot plate and guard heaters with their knobs. Readings are taken once temperatures are steady, and the standard listed is ASTM C177-04.
What to Specify When Ordering
- Quantity — the number of guarded hot plate units required.
- Electrical supply — 230 V 50 Hz, 230 V 60 Hz or 120 V 60 Hz, single phase.
Frequently Asked Questions
What materials is the guarded hot plate for?
It is used to test the thermal conductivity of non-metallic materials, and the thermal conductivity of different materials can be determined at different temperatures.
Why is a guard ring used?
The guard ring around the central hot plate has its own heater, so heat from the centre flows straight through the specimens rather than sideways, which keeps the measured heat flow one-dimensional.
How many specimens are tested at a time?
Two specimens are inserted between the hot plates and the two water-cooled cold plates, which are clamped together to give a uniform pressure.
Which standard is listed for it?
The standard listed for it is ASTM C177-04, and the unit is a bench-top guarded hot plate design for non-metallic materials.
Does the unit need cooling water?
Yes. The two cold plates are water-cooled, and the unit requires an outside water supply to cool them during a test.
What heaters are fitted?
The hot plate heater and the guard ring heater are each rated at 500 W and each has its own control knob. Power for both comes from a service module, which also measures the power and indicates the temperatures.
