B+B Sensors REFZ-12Z-SET2 Humidity Reference Cells

This set contains humidity reference cells that are used for the checking and adjustment of capacitive type humidity probes. The cells can also be used in scientific applications as a humidity standard. Each cell has a test chamber that is separated from the solution by a diaphragm so that the test sensor is not contaminated by the solution and the high quality diaphragm enables the contactless checking of measuring probes. Applications include calibration of hygrometers and humidity probes, defined humidity storage of probes, humidification cell for research and experimental purposes.
