leads embedded in solid glass. Hermetically sealed, they have excellent stability over long periods
of time under continuous exposure to harsh environments. They retain excellent stability at
temperatures to 325°C (617°F) for storage or continuous operation, and to 550°C (1,022°F) for
intermittent operation. For complete product information request VECO Bulletin MGR061.

temperature curve to within a stated tolerance over a specified range. Isotherm
units can be supplied such that the units within a group track each other at one
or more points, or over a specified temperature range, to within a given tolerance
on resistance. Further information is contained in Technical Bulletin MTM141.
