Type 60/65/85/100 Specifications
All thermoprobes are aged for extended periods of time. As
such, they exhibit excellent stability for all service tempera-
tures at or below the aging temperature. Thermoprobes that
are manufactured with material system “E” are aged at 221°F
(105°C); those manufactured with a material system having
a 77°F (25°C)/257°F (125°C) ratio of 16.9 or less are aged at
392°F (200°C); and all other material systems are aged at
572°F (300°C). Intermittent operation at temperatures up to
1112°F (600°C) is permissable, however, degraded stability will
result when the aging temperature is exceeded. This appiles
to the NTC Type P20/25/30 also.

Resistance vs temperature characterstics: The nominal resistance range for the zero-power resistance at 77°F (25°C) is shown for each miniature bead-in-glass thermoprobe type and each
available material system. Each material system is denoted by an ordering code letter, a referenced curve number and the nominal 77°F/257°F (25°C/125°C) resistance ratio.
