Sheath Thermometer Construction

The element is constructed from a high purity platinum wire and is formed and processed to produce a strain free construction. This is then introduced into a platinum sheath which is helium filled to approximately 1/3 atmosphere at 20°C to reduce the response time to approximately 2 seconds.

Platinum Thermometer Application

The thermometer is suitable for use in the temperature range 13.08K to 330K and may be used totally immersed in a liquid, provided the liquid is a good electrical insulator.
