An isotherm is a line of equal or constant temperature on a graph, plot, or map; an isopleth of temperature. For example, isotherms are commonly seen on weather maps to show large-scale temperature distributions. Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter. ... Contour map A contour line (also isopleth, level set, isogram or isarithm) for a function of two variables is a curve connecting points where the function has a particular value. ... Temperature is the physical property of a system which underlies the common notions of hot and cold; the material with the higher temperature is said to be hotter. ...

Isothermal Technology Ltd is the world's leading supplier of temperature calibration equipment.
As early as 1986, Isothermal became an approved British Calibration Service Laboratory (now UKAS) and since then Isothermal has continued to has continued to invest resources in the development of the laboratory which is the focal point of Isotech product development.
Our product development program often means UKAS have difficulty in devising a method of assessing our capability when we want to incorporate the product into the laboratory.
