Tiger Optics Halo 3 H2O Trace Moisture Analyser
This report details tests carried out to evaluate the performance of a Tiger Optics Halo 3 H2O Moisture Analyser. The instrument measures the amount of water vapour present in the gas under analysis and can be used to measure the humidity of various different gas species including nitrogen and carbon dioxide. Tiger Optics are based in Pennsylvania, USA. The evaluation programme was devised by the National Physical Laboratory (NPL), UK in response to a test requirement list supplied by an Evaluation International member company which also supplied the instrument for evaluation. Humidification of the various gas species measured was made using the NPL Multi-gas, Multi-pressure humidity generator.
