Description
Fluke SPRT 220-660C 19 Inch w/Lemo Connector, Calibration Certificate
(item no. 2068693)
Designed and manufactured by our primary standards metrologists, the strain-free sensing element in the 5699 meets all ITS-90 requirements for SPRTs and minimizes long-term drift. After one year of regular usage, drift is less than 0.008°C (<0.003°C is typical). Even lower drift rates are possible depending on care and handling. A fifth wire for grounding is added to the four-wire sensor to help reduce electrical noise, particularly for AC measurements. Finally, you can get an improved version of an old industry-standard Inconel-sheathed SPRT.
Features
- Range to aluminum point (660°C)
- Inconel™ and platinum sheaths guard against contamination
- Less than 8 mK/year drift
- Many calibration options available including by fixed point
- Fifth wire provides shield ground
