Water-Vapor Isotope Analyzer

* Unsurpassed accuracy and precision
* Low power requirement (120 watts)
* Extremely wide range of concentrations
* Fast measurement response time (2 seconds)

Now you can accurately measure the 18O/16O and D/H ratios in ambient water vapor (1000 ppm–saturated) rapidly with high precision (e.g., better than 0.5‰ and 2.0‰ in a measurement time of 2 seconds, respectively – of course, longer averaging times may be used to provide better precision, if desired). Our Water-Vapor Isotope Analyzer requires only 120 watts of power and does not require any sample preparation or user intervention, which enables long-term studies of water-vapor isotopes with unprecedented performance. In addition, the WVIA provides simultaneous measurements of water vapor mixing ratio [H2O] with ppm-level precision.

The rugged, field-portable packaging makes this instrument ideally suited for a myriad of hydrological, atmospheric science, and industrial monitoring applications. The instrument includes an internal computer that can store data practically indefinitely on its internal hard drive (for applications requiring unattended long-term operation) and send real-time data to a data logger through its analog and digital (RS232) outputs. In addition, an Ethernet connection allows remote access to data files stored on the instrument’s hard drive. The instrument also includes, as standard, an embedded keyboard, mouse and monitor, for your convenience.
