logging or event logging/recording. For the RH sensor, it is recommended to align with a High
concentration level using the 75% sensor salt, NaCl (sodium chloride), or a Low concentration
level using the, the 33% sensor salt, MgCl (magnesium chloride). (To order sensor alignment
salts, refer to an online vendor such as, colepalmer.com.)
