Thermal Conductivity of Liquid Manufacturer,Supplier and Exporter in India
Product Code : EL-HTL-10053
Jlab Export is a leading Thermal Conductivity of Liquid Manufacturer,and suppliers in India
Thermal Conductivity of Liquid (code EL-HTL-10053) is a guarded hot plate apparatus that measures the conductivity of a liquid held in a test cavity between an electrically heated plate and a water-cooled cold plate. A main heater, ring guard heater and top guard heater make up the hot plate assembly, housed in a box insulated with glass wool. This liquid conductivity rig is made by JLab in Ambala, India.

Why the Liquid Is Heated From Above
The hot plate assembly sits over the liquid test cavity, with the cold plate on the other side of the layer. Warm liquid at the top and cooler liquid below form a stable layer, so buoyancy cannot set up convection currents and heat crosses the liquid by conduction alone. The ring guard heater stops heat escaping sideways from the main heater, and the top guard heater stops it rising, so the main heater output goes down through the liquid to the cold plate. Each of the three heaters has its own dimmerstat, and the guards are trimmed until their temperatures match the main heater.
Finding k for the Liquid
At steady state the digital voltmeter and ammeter give the main heater power, Q = V × I. With δ as the depth of the liquid layer, A the main heater area and Th − Tc the temperature difference across the layer from the multichannel indicator, Fourier’s law gives k = Q δ / (A (Th − Tc)). The cavity should be filled without trapped air bubbles, since air conducts far less heat than most liquids and would lower the result.
