Please read general information

These single and dual-oven instruments are the basic H2O models. The 61-H2O single-oven model can produce concentrations over a 10:1 range and from over 1000 ppm down to 0.1 ppm in nitrogen and other inert background gases. The dual-oven 261-H2O model that can generate a concentration range of 100:1. An internal purge of dry gas is used to minimize contamination from atmospheric moisture in low concentration service.
