Thermistors
121 Series
Standard glass probe. -60 °C to 300 °C [-76 °F to 572 °F]
121 Series Thermistors are shock resistant, rugged, glass-encapsulated units that are often suited for immersion in fluid and convenient for mounting in air sensor assemblies. Also available in a mini glass probe configuration (120 Series).
