I、Product Introduction

The thermal conductivity meter using short-hot wire method is based on the conservation of energy, which solves the thermal conductivity and thermal diffusion coefficient of the liquid by solving the steady-state thermal conductivity problem, and derives the thermal conductivity of the liquid medium by measuring the temperature rise response of the sensor.

The short hot wire method for measuring thermal conductivity belongs to the transient test method, which has the advantages of short test time, fast speed, small sample volume, and can effectively detect and eliminate the influence of natural convection on the measurement. The supporting control and analysis system of this equipment is independently developed and has test to be accurate. The sensor can measure the thermal conductivity of molten salt without special insulation treatment. This equipment is developed for molten salt and can be further extended to the measurement of thermal conductivity of other melts and even gases.
