Description and Specification for Lab Tenders
Astra Scientific Guarded Hot Plate with data acquisition.
The Offers basic experiments bench top unit is for testing of thermal
conductivity of non-metallic materials using guarded hot plates bases on
ASTM C177-04.
The equipment consists of a central heater with hot plates, a guard ring
with heater and hot plates, and two water-cooled cold plates. Two
specimens are inserted between the hot plates and cold plates. The
assembly is encased in a test cabinet with insulation. The cold plates
are clamped together to provided a uniform pressure.
The experimental unit is equipped with temperature sensors at the inlet
and outlet of the air duct. The air velocity is measured to determine
the airflow rate. Heating power and flow rate are adjusted and displayed
via the software.
The microprocessor-based instrumentation is well protected in the
housing. The software consists of software for system operation and for
data acquisition and educational software. is connected to the PC via
USB.
A service module provides power supply and heater control unit, power measurement unit and temperature indicators.
