frost point hygrometer
The strong cooling necessary for these measurements is provided either by multistage Peltier devices or by evaporating low-boiling-point (cryogenic) fluids like liquid nitrogen. Using this technique, frost points down to -100°C can be measured. Electrical resistance wires are used to provide heating.
