Thermal Conductivity Gas Analyzers


Model Number: SSI 607 TC

Thermal Conductivity is a basic property of gas related to ability to conduct heat. At one end are gases like Hydrogen and Helium that are good conductors; at other end are Nitrogen, Argon and Carbon Dioxide that do not conduct well.

 

 

Salient Features
Transducers : From Gow Mac USA
Range : 0-100.0% Standrad, other ranges on request
Sample / Reference Gas Pressure : 0.1 to 10.0 Kg/cm2
Power : 220 V, 50 Hz AC

 

Description

Thermal Conductivity is a basic property of gas related to ability to conduct heat. At one end are gases like Hydrogen and Helium that are good conductors; at other end are Nitrogen, Argon and Carbon Dioxide that do not conduct well. In Reference Channel a pure gas is introduced while the Sample Channel carries the sample. The signal produced is proportional to the difference in Thermal Conductivity between the two channels.

It is possible to carry out Gas Purity Checks, Mixture Composition Estimation and also safety Monitoring e.g. Oxygen in Hydrogen where it is widely known as Katharometer.

 

Special Features

  • High Sensitivity TCD
  • Flow Monitoring and Control standard Feature
  • Alarm with indicating light and SPDT relay standard Feature
  • Insensitive to flow rate in operating region
  • Simple to use
  • Can be adaped for many uses.
