TB8 Bi-Metal Thermometer
Brand: Nuova Fima
These instruments are designed for use in chemical, petrochemical processing industries.
They are built to resist the most severe operating conditions created by the ambient environment and the process medium.
An TIG welded case/bulb strengthens the whole construction.
A leak tight fit is ensured if the instrument is filled with a dampening fluid to prevent damage due to vibration.
