Fluke Calibration 5606 [5606-50-J] Full Immersion PRT Banana Plug Probe –200 to 160 °C

Fluke Calibraton 560650J Full Immersion PRT Probe with Banana Plugs, 2 in. x 1/8 in., -200 °C to 160 °C, 8 ft. Lead is designed to perform in extreme environments where both the transition junction and the lead wires are required to withstand temperatures covering the entire operating range of the probe. The term "immersion", in this case, means exposure to temperatures other than ambient, and does not necessarily refer to the medium to which the PRT and its components are subjected.

Applications where "full immersion" of probe, transition junction, and lead wire is required can include calibration or validation of sensors used in a laboratory, bio freezers, walk-in refrigerators, autoclaves, ovens, stability test chambers, furnaces, or incubators. Other applications might include IQ/ OQ/PQ qualification procedures, temperature mapping, or data logging in temperature controlled spaces or environmental chambers.

The Fluke Calibration 5606-50-J is just two inches (50 mm) in length with a sheath diameter of 1/8 inch (3.1 mm). Since it can be fully immersed over its entire temperature range, you do not have to worry about calculating minimum immersion depth - immerse the entire probe, transition junction, and lead wires, in either non-corrosive liquids or dry mediums ranging from -200 °C to 160 °C.

The 100 Ohm precision sensing element (alpha = 0.00385) is specially constructed to prevent the ingress of moisture while achieving calibration accuracies of up to ± 0.05 °C. You get both accuracy and flexibility built into a small, durable package.

The lead wires of the 5606-50-J are made of single-conductor enameled copper wire, which prevents as much moisture from wicking to the sensing element as it would if a more common, stranded lead wire were used. The diameter of the lead wire is no greater than 0.2 mm, making it easy to run lead wires through a freezer door to your readout or transmitter with effectively zero energy loss. The 5606-50-J has been proven in common heat transfer fluids such as silicone oil, mineral oil, ethanol, and even liquid nitrogen with no degradation of the transition junction seal or lead wire insulation.
