Thermal Conductivity Sensor is a bulk property as well as chemical specific detector. This is widely utilized in gas chromatography to sense small changes in the thermal conductivity. It is designed to quantify different gases like methane, helium, hydrogen, etc. with percentage volume. The operating temperature of this sensor ranges from 400 to 500 degree C. This is widely used in different sectors from oil and gas, confined space entry, mining, etc. for checking indoor air quality and leakage of gases. This is designed to ensure complete industrial area protection.
