Fluke 5649/5650 | Type R and Type S Thermocouple Standards
- Temperature range of 0 °C to 1450 °C.
- Uncertainties as good as 0.15 °C over most of that range.
- Calibrated at four fixed points (Sn, Zn, Al, Ag) and then extrapolated to 1450 °C.
Fluke 5618B Small Diameter Industrial RTD
- Sheath diameter of 3.2mm (0.125 in), ensuring reduced response time without compromising precision.
- NVLAP-accredited calibration from -200°C to 500°C, lab code 200706-0.
- Reduced measurement error in short immersion depth applications by conducting less heat between ambient and the sensor.
Fluke 5615 Secondary Reference Temperature Standards
- Inconel™ 600 sheath that’s 305 mm (12 in) long and 6.35 mm (0.250 in) in diameter
- Calibrated accuracy of ± 0.012 °C at 0 °C.
- NVLAP-accredited calibration, lab code 200706-0.
