Description
The Fluke 5615 is a secondary reference temperature standard, sometimes called a Platinum Resistance Thermometer (PRT). This means it’s a very accurate thermometer used to calibrate other thermometers and temperature measurement devices.
Here’s a breakdown of what that means:
- High Accuracy: The 5615 is designed to measure temperatures with very high precision. This is essential for ensuring the accuracy of other temperature measuring instruments.
- Stability: It maintains its accuracy over time, providing consistent and reliable readings. This is crucial for long-term measurements and calibrations.
- Platinum Sensing Element: At its core is a very pure platinum element. Platinum’s electrical resistance changes predictably with temperature, making it ideal for accurate temperature measurement.
- Durable Construction: It’s built to withstand the demands of industrial environments, with a protective sheath (often made of Inconel) to protect the delicate sensing element.
- Calibration: It comes with a calibration certificate from a recognized accreditation body (NVLAP), ensuring its accuracy is traceable to national standards.
Here’s where you might find a Fluke 5615:
- Calibration Labs: Used to calibrate other temperature sensors and instruments.
- Industrial Processes: Monitoring and controlling critical temperatures in manufacturing, pharmaceuticals, and other industries.
- Research and Development: Ensuring accurate temperature measurements in experiments.
