Thermistors
129 Series
Matched large glass probe. -60 °C to 300 °C [-76 °F to 572 °F]
129 Series Thermistors are designed for use as precision sensing elements where curve-matched interchangeability is required for precise temperature control and precision temperature indication. These highly reliable products consist of a matched pair of hermetically sealed thermistors and may be selected to tolerances only limited to the system’s capability available to test them. Also available in a matched mini glass probe configuration (128 Series).
