FLUKE Full Immersion PRT
Ultra-Compact, Reliable, and Designed for Complete Immersion
Total Flexibility for Extreme Environments
The Fluke 5606 Full Immersion Platinum Resistance Thermometer (PRT) offers an unmatched solution for applications where full immersion of the probe—including transition junction and lead wires—is required. With a compact length of just two inches (50 mm) and a sheath diameter of only 1/8 inch (3.1 mm), the 5606 delivers accuracy and durability in the tightest spaces.
Key Features and Benefits
- Truly Full Immersion – No need to calculate minimum immersion depth. Simply immerse the entire probe, transition junction, and lead wires over the entire operating range—from –200 °C to 160 °C—in either non-corrosive liquids or dry mediums.
- High Accuracy in a Compact Size – Achieve calibration accuracies as good as ±0.05 °C, thanks to the specially constructed 100 Ω precision sensing element (alpha = 0.00385) that also blocks moisture ingress.
- Superior Moisture Protection – Single-conductor enameled copper lead wires prevent moisture from wicking into the sensing element, offering better protection than traditional stranded leads.
- Flexible and Easy Installation – Lead wires measure no greater than 0.2 mm in diameter, making it simple to route through tight spaces—such as a freezer door—without energy loss.
- Proven Durability – The 5606 has demonstrated excellent performance in heat transfer fluids like silicone oil, mineral oil, ethanol, and even liquid nitrogen, with no loss of integrity in the transition junction or lead wire insulation.
Engineered for Demanding Applications
The 5606 Full Immersion PRT is specifically designed to thrive in extreme environments. Both the transition junction and lead wires are built to endure temperatures covering the full probe range, ensuring complete reliability in challenging conditions.
“Immersion” means exposure to extreme temperatures—not just being submerged in a liquid—making the 5606 ideal for a wide variety of rigorous uses.

Temperature CalibratorsFLUKE 724 Temperature Calibrator
Everything you need to troubleshoot and calibrate temperature sensors and transmitters
The Fluke 724 is powerful yet easy-to-use temperature calibrator that sources and measures 10 thermocouple types, and 7 RTD types, plus volts and ohms. It also measures mA while simultaneously supplying loop power to the transmitter. Use it to test and calibrate almost any temperature instrument, so you only need one tool to expertly test all the temperature sensors and transmitters in your plant.
The Fluke 724 even handles high-speed pulsed RTD circuits and provides loop power. The dual-line measure/source display lets you source temperature and view loop current at the same time. And with its simple, “no menus” controls, you’ll be able to get all your testing done faster. Whether you’re performing fast linearity tests using the 25% and 100% step functions, or performing a remote test using the auto step or auto ramp feature the Fluke 724 will help you get the job done.
Built to help you work quickly
With its compact, easy-to-carry streamlined shape, the Fluke 724 also features a bright backlit display that lets you work in low light conditions. The large battery capacity (four AA alkaline batteries) gives you long runtimes, and the easy-to-access battery door makes it quick to change out batteries when necessary. All this in a rugged, reliable package designed to stand up to field use.

What is a Blackbody Calibrator?
A blackbody calibrator (or blackbody source) is a device that emits thermal radiation with high emissivity, typically near 1.0. This makes it behave closely to an ideal blackbody, emitting radiation according to Planck’s law.
Blackbody calibrators are essential tools for ensuring the accuracy of:
- Infrared thermometers
- Thermal imagers
- Non-contact temperature measurement devices
By aiming a device under test at the precisely controlled blackbody target, users can verify and adjust readings to ensure accuracy and compliance with calibration standards.
