Thermometrics SP Series of Ultra-Stable Probe NTC Thermistors receive additional processing to assure their continuous use in one of three temperature classes and are categorized into one of six stability groups. These thermistors may be used in all temperature measurement and control applications with the added assurance of long term stability and reliability. They are ideal for use as secondary standards in laboratories.
