Fluke Calibration 5615-12-B

• Secondary Standard PRT
• 6.35 mm x 305 mm (0.250 x 12.0 in)
• -200 to 420 °C
• For years, youve relied on our 5612, 5613, and 5614 Secondary Reference Probes
• These field-durable, lab-accurate PRTs have been replaced by the 5615, which comes with a accredited calibration
• The 5615-12 is a Platinum Resistance Thermometer (PRT) with an Inconel™ 600 sheath thats 305 mm (12 in) long and 6.35 mm (0.250 in) in diameter
• It is a secondary reference temperature standard designed to bridge the gap between the highest laboratory standards and industrial or second-tier lab locations
• It has short-term accuracy of ±0.013 °C at 0.01 °C
• The element is constructed of reference-grade platinum wire (99.999 % pure) for excellent stability
• The wire is wound in a coil and placed in a mandrel where its uniformly supported in a manner that virtually eliminates hysteresis
• The electrical configuration is a four-wire current-potential hookup that eliminate the effects of lead-wire resistance
• These Inconel™-sheathed probes have a fully supported sensing element, making them more durable than SPRTs
• The element is protected in an ultrahigh-purity ceramic case with a hermetic glass seal to improve output stability by locking out moisture and contaminants
• This probe comes calibrated with ITS-90 coefficients, making it compatible with many excellent readout devices, including Harts 1529 Chub-E4, 1560 Black Stack, and 1502A Tweener
• It bridges the gap between a 100-ohm industrial RTD and an SPRT
• For those needing faster thermal response, or where diameter and immersion depth are problems, order the 5615-9 or 5615-6
• These probes are excellent reference probes for comparison calibrations in a Hart dry-well
• The sheaths of the 5615-6 and 5615-9 are 4.76 mm (0.188 in) in diameter
• A printout of sensor resistance is provided in 1 °C increments for each probe
• The 5615-9 and 5615-12 are calibrated from -196 °C to 420 °C (The 5615-6 is calibrated to 300 °C)
