Last year, Hart’s primary standards design team introduced the 5629 Gold-Platinum Thermocouple as a temperature standard from 0°C to 1000°C. As a thermocouple standard, its performance is unmatched. Again using the best materials and production techniques, we are pleased to introduce our Model 5650 Type S Thermocouple. You won’t find a better-performing type S from anyone else. No one!

Made from the finest platinum and platinum-rhodium alloy, the 5650 Type S covers 0 to 1450°C with uncertainties less than 0.5°C over most of that range. With four different models to choose from, we have a type S thermocouple to fit your application.

The measuring junction of the 5650 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 measurement junction as the probe attaches to your micro voltmeter or Hart Black Stack.

Each 5650 comes from a spool of wire that has been sample tested using fixed-point standards to ensure uncertainties less than 0.5°C up to 1100°C. From 1100°C to 1450°C, the uncertainty increases linearly to 3.0°C. If you need greater accuracy, order an individual calibration with fixed-point standards to reduce uncertainties to ±0.25°C below 1100°C and increasing linearly to ±2.0°C at 1450°C.

The probe assembly can be easily disassembled for performing your own bare-wire calibrations.
