This is a user manual of Hanna HI 7101 and HI 7102 RH calibration kits. These kits include two thermally isolated chambers, each one equipped with a cap and three bottles containing the appropriate precalibrated saturated salts to produce a known RH value: two 15-gram bottles of Lithium Chloride (LiCl) and one 33-gram bottle of Sodium Chloride (NaCl).
The document provides instructions for using the HI 7101 and HI 7102 portable humidity calibration chambers. These kits include thermally isolated chambers equipped with precalibrated saturated salts (Lithium Chloride and Sodium Chloride) to produce known Relative Humidity (RH) values of approximately 11.1% and 75.4%. The manual specifies compatible Hanna Instruments hygrometer models for each kit.
The portable chambers measure only 190 x 115 x 110 mm.
The calibration kit needs 4 hours for stabilization.
A value of 0.0% is required, though a reading between 0.0% and 1.0% RH is also acceptable.
