Description
Overview
The Fluke Calibration 5615-12-D is a secondary reference platinum resistance thermometer (PRT) designed for laboratory and industrial temperature calibration applications. It features an Inconel 600 sheath measuring 305 mm (12 inches) long with a 6.35 mm (0.250 inch) diameter, providing durability and accuracy for critical temperature measurement work.
The probe bridges the gap between high-precision SPRTs (Standard Platinum Resistance Thermometers) and industrial RTDs (Resistance Temperature Detectors), offering the stability of a reference-grade instrument with improved durability.
Key Features
- Secondary reference temperature standard with ±0.013 °C short-term accuracy at 0.01 °C
- Reference-grade platinum wire (99.999% pure) for excellent long-term stability
- Inconel 600 sheath, 305 mm long × 6.35 mm diameter for enhanced durability
- Four-wire electrical configuration eliminating lead-wire resistance effects
- Fully supported sensing element with minimal hysteresis
- Ultrahigh-purity ceramic case with hermetic glass seal for output stability
- Pre-calibrated with ITS-90 coefficients for immediate use
Applications
- Laboratory temperature calibration and comparison standards
- Industrial temperature measurement in harsh environments
- Comparison calibrations with Hart readout devices
- Pharmaceutical and medical facility calibration
- Secondary laboratory temperature reference standards
