The Nitrogen Boiling Point Apparatus is designed specifically to realize and maintain
the liquid-vapor equilibrium (boiling point) of nitrogen or argon, for the calibration of
thermometers on the International Temperature Scale of 1990.
Furnace Temperature Calibrator. Temperature range 50°
C to 700°
The Medium Temperature Furnace is designed specifically to realize and maintain the
freeze plateaux of Indium, Tin, Zinc and Aluminum Cells, for the calibration of
thermometers on ITS-90.
