Note 1: The maximum continuous media temperature for this gauge
is 212°F. However, higher temperatures can be maintained safely for
short term exposure per table to the right. The user should consider
temperature error and gauge component degradation when exposing gauge to any media or ambient temperature above 212°F. For
continuous use in either ambient or media temperatures above 212°F,
a diaphragm seal or other heat dissipating means is recommended.
Consult factory for technical inquiries and application assistance.
