Unrivalled accuracy for binary gas mixture measurements

Hummingbird’s Unique TruRef sensing technology offers stable, reliable results for a range of binary mixtures, including nitrogen, helium, hydrogen and argon. The patented design locates both the reference and measure elements in the sample gas, eliminating errors caused by changing sample conditions. This gives the world’s first true Thermal Conductivity gas measurement, delivering an unmatched accuracy ideal for purity and process control applications.
