Micro Essential Lab HJH-650 Hydrion Humidicator Paper

Hydrion Humidicator Test paper measures relative humidity with distinct color changes at 20%-40%-50%-60%-80%.  In the presence of water vapor, the test paper will change colors; from a deep blue at 20% RH to a bright pink at 80% with well defined intermediate colors.  The paper may be used to demonstrate the need for dehumidifiers in homes, offices, or storage areas considered at risk for high or low humidity levels.  With the use of appropriate tables, the paper can also be used to estimate the dew point or frost point.

Each 0.5" x 50' roll of Hydrion Humidicator Test Paper in a jumbo sized dispenser will provide more than 200 test strips and comes sealed in foil to guard against moisture.  Includes 1 color chart.
