1.1 This specification covers glass thermohydrometers of various scale graduation systems, intended for use in a variety of ASTM Test Methods.
1.2 The thermohydrometers presented in this standard are not exact replacements for the thermohydrometers in Specifi-cation E100; the thermometers have larger maximum permis-sible scale errors than do their Hg-filled counterparts. The user should decide if these thermohydrometers are appropriate for use in his or her application.
