Material Properties of the Available Probe Housings and
Sensor Sockets
1 = very good 5 = unsuitable
1) not resistant to hydrochloric or sulfuric acid
2) not resistant to strongly oxidizing media (conc. sulfuric acid, nitric acid or hydrofluoric acid)
3) not resistant to ketones, amines, fuming sulfuric and nitric acid
The stated values are reference values and provide general information. Concentrations, temperatures, mechanical influ-
ences and load duration influence the material resistance. Therefore, no guarantee is given for the stated values. A pre-
test is recommended for cases where there has been no prior experience using the material in the process. Mixtures of
substances constitute a prime example.
