MAGNI 521

Description

Temperature is one of the most important variables in industrial processes.
It is therefore necessary to have reliable instruments, manufactured to guaranteed standards and pratically maintenance free.
Our range of inert gas thermometers satisfies all these requirements.
Sturdy and reliable industrial thermometers, particularly suited for heating and naval plants, ovens and machine tools. The inert gas used (nitrogen) is not toxic and does not pollude the enviroment.
These instruments are therefore safe and give technical performances (precision and speed of response) superior to previous mercury based models. Construction according to EN 13190.
