User-friendly 5615-12-d Fluke Reference Probe New Series [TQ80Zbma]

5615-12-D Fluke Reference Probe

The Fluke 5615-12-D Reference Probe is a premium temperature measurement tool designed for precision and durability. This probe is a secondary reference temperature standard, bridging the gap between the highest laboratory standards and industrial or second-tier lab locations. Its exceptional accuracy and robust construction make it an ideal choice for critical temperature measurements.

Key Features and Specifications

The 5615-12-D features a Platinum Resistance Thermometer (PRT) with an Inconel™ 600 sheath, offering a length of 305 mm (12 in) and a diameter of 6.35 mm (0.250 in). This probe boasts a short-term accuracy of ±0.013 °C at 0.01 °C, ensuring reliable and precise temperature readings. The element is constructed of reference-grade platinum wire (99.999 % pure) for excellent stability, and the wire is wound in a coil to virtually eliminate hysteresis. The electrical configuration is a four-wire current-potential hookup, which eliminates the effects of lead-wire resistance for enhanced accuracy.

Practical Applications and Compatibility

The Fluke 5615-12-D is not just a reference probe; it is a versatile tool for a wide range of applications. Its fully supported sensing element, made more durable than standard SPRTs, ensures long-lasting performance. The probe is protected in an ultrahigh-purity ceramic case with a hermetic glass seal, improving output stability by locking out moisture and contaminants. Calibrated with ITS-90 coefficients, this probe is compatible with many excellent readout devices, including Hart’s 1529 Chub-E4, 1560 Black Stack, and 1502A Tweener. It effectively bridges the gap between a 100-ohm industrial RTD and an SPRT, making it a versatile solution for various temperature measurement needs.
