Dewpoint portable hygrometer type DPH-31
Product description
DPH-31 is a microprocessor gas moisture meter designed to measure humidity in air and process gases in the field and on the site in a simple and quick way. The built-in lithium-ion battery allows self-sufficient operation for many hours. The DPH-31 meter has a built-in complete sampling system that can be connected to any pipe or system, both in the case of free flow and (using a pressure integrated valve) (up to 3MPa).
