Hope you will not mind it ...
Density is specific for each substance. Also the measurement is generally simple.
Zero degrees Celsius is the melting point of ice and the freezing point of water depending on which substance you have.
To check the precision of an instrument its apparent measurement must be compared to a known measurement. The difference between the measured quantity divided by the known quantity is expressed as a % precision of the instrument, or calibration. Most instruments when being calibrated are tested against multiple known quantities throughout the range of the instrument. Thus the precision of the instrument is determined throughout it's full range of measurement.
There are special angle-measuring instruments which you can use to measure the angle.
It measures water vapor content in the atmosphere. In general a Hygrometer is any of various instruments for measuring humidity
