5649/5650 Type R and Type S Thermocouple Standards
Type R and Type S thermocouples deliver precise temperature measurements from 0 °C to 1450 °C. Choose from two sizes to suit your needs.
Product Overview
The measuring junction of both the 5649 and the 5650 thermocouples is encased in a 0.25-inch (6.35 mm) alumina sheath that can be ordered in lengths of 20 or 25 inches (50.8 or 63.5 cm) to fit the specific requirements of your application. A reference, or “cold," junction may also be ordered. The reference junction uses a stainless steel sheath and is 8.25 inches long (21 cm) by 0.188 inches in diameter (4.8 mm). The thin diameter minimizes the immersion depth needed, but the extra length ensures you can get all the immersion you like.
Special tin-plated, solid-copper connecting wires with ultra-low EMF properties are used to help retain the integrity of your thermocouple measurement junction where the probe attaches to your micro voltmeter or Hart Black Stack.
Each thermocouple probe comes with an individual calibration with fixed-point standards to reduce uncertainties to 0.12 °C to 0.37 °C from 232 °C to 962 °C and 0.37 °C to 2.5 °C, increasing linearly >962 °C to 1450 °C (extrapolated).
The probe assembly can be easily disassembled for performing your own bare-wire calibrations.
