Kestrel RH Calibration Kit

Re-calibrating the Relative Humidity (RH) sensor of the Kestrel may be necessary if the RH measurement has deviated or if the sensor has been replaced.  The large container serves to create a uniform atmosphere, while the smaller containers house a saturated salt solution, which, when enclosed in a confined space, produces accurately delineated humidity. The RH calibration kit includes the following items: Three clear, sealable containers One container with magnesium chloride solution One container with sodium chloride solution Two wooden scrapers An insulated carrying case to hold all of the above and maintain a stable environment while performing calibration NSN Number 6660015600929
