We consider only the resistance of the parts accessible in use (head and bezel). The contact are supposed to be protected.
The resistance to chemical is usually depending on concentration and temperature.
For the ZB5AS844, here is the result :
Where NOK = dimensions change > +/- 12%
OK = dimensions change < +/- 5%
In conclusion, the ZB5AS844 head is NOT
compatible with sulfuric acid at any concentration.
