Q11.4 - Helium Purity Meters and Purifiers

Q11.4-001

Thermal Conductivity Meter

• readout proportional to the difference in the thermal conductivities of the sample and pure helium.
• Includes digital display showing the percentage of air in helium.

Q11.4-002

Helium Purity Meter - high purity option

• Same as Q11.4-001 except with additional display resolution from 0.001% to 19.999% and precision flow controller to make accurate comparisons between reference gas and sample gas.

Q11.4-003

Helium Purity Meter - remote controlled valve option

• Provides a remote controlled (motorized) valve to switch between the sample gas and reference gas.
• Useful for automating the readings when the high purity requires that comparison with a reference gas is required.

Q11.4-004

Helium Purity Meter - gas chromatography separation column option

• Order with motorized valve option to allow display on a chart recorder of the elution time delays of the impurities
• allows measurement of the relative concentration of oxygen and nitrogen in the contaminants.

Q11.4-HePur-24
