are available upon request.
Materials:
Carbon Steel (C-1018); Brass (ASTM B-16),
A.I.S.I. 304, A.I.S.I. 316, Monel. Many other materials
available upon request.
Additional Designs:
Other designs of wells to fit this class of thermometer are
available. These include socket weld, heavy duty and
flanged types.
