SP Series

Ultra-stable Probe

Thermistors

The NTC Type SP60, SP65, SP85, and SP100 Ultra-stable Probe Thermistors have similar construction and

dimensions to the Type P60, P65, P85, and P100 Probe Thermistors. Ultra-stable Probe Thermistors receive

additional processing to assure their continuous use in one of three temperature classes and are catego-

rized into one of six stability groups.

Stability Classes (By Nominal Resistance at 77°F (25°C)

Ultra-stable probe thermistors availability depends upon nominal resistance at 77°F (25°C). Stability class is

indicated by a code letter for temperature class and a code number for stability group.

Example: “A1” = .02% maximum change per year at 221°F (105°C) maximum temperature.

*Special tolerances are available on request. Consult the factory for special resistance tolerances, non-standard resistances and/or non-

standard temperatures.

**The zero-power resistance at 77°F (25°C), expressed in ohms, is identiﬁed by a three digit code number. The ﬁrst two digits represent

signiﬁcant ﬁgures, and the last digit speciﬁes the number of zeros to follow. Example: 2k Ohms =“202”. The standard resistance val-

ues are from the 24-Value series decade as speciﬁed in Military Standard MS90178. 1.0 / 1.1 / 1.2 / 1.3 / 1.5 / 1.6 / 1.8 / 2.0 / 2.2 / 2.4
