The DEW10 Hygrometer (basically a cooled mirror) offered accurate short-term measurement capability but had several disadvantages when used in long-term applications under field conditions. This hygrometer is at the core of the reasons that the 023A Bowen ratio system is currently unavailable. We are attempting to support existing customers (emphasis on Replacement Parts) without selling additional systems that use this component.
