An altitude meter is an instrument used to calculate the altitude of an object over a fixed level. The measurement of altitude is called altimetry, which is associated to the term bathymetry, the measurement to calculate depth under water. This can be used for surveying.
Dilatometer has been used in the fabrication of metallic alloys, compressed and splintered refractory compounds, glasses, composite materials and plastics. Sample length may be 50mm(max) or 25mm;Sample diameter range is 68mm;Measuring range and error may be is 5 mm 0.1%or 2.5 mm 0.1%.It has a heating rate of 1 30 oC minute.Dilatometer is also used to monitor the progress of chemical reactions.
