Hermetically Sealed Tip Insulated Thermocouples Calibration needed?:No The standard AA batteries canThese PFA insulated thermocouple wire sensors are hermetically sealed at the sensor tip to provide continuous PFA protection over the measurement junction. This hermetic seal design provides a small, flexible, and electrically isolated thermocouple, suited to a variety of applications. When using longer lengths, #20AWG stranded wire construction is available to reduce sensor resistance. For a hermetically sealed RTD sensor, see the HSRTD Popular
