5606 and 5607 Full Immersion PRTs for laboratory
freezers, autoclaves, and furnaces

5606 and 5607 Full Immersion PRTs

  • 5606: –200 °C to 160 °C
  • 5607: 0 °C to 450 °C
  • Calibration accuracy of ± 0.05 °C
  • Transition junction and lead wires can withstand full PRT temperature range
  • Unique probe seal of 5606 prevents ingress of moisture
  • Calibration not included; NVLAP-accredited calibration optional

The 5606 and 5607 Full Immersion PRTs are 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. (“Immersion” in this case simply 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 laboratory or 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 5606 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 don’t 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 W precision sensing element (alpha = 0.00385) is specially constructed to prevent the ingress of moisture while achieving calibration accuracies as good as ± 0.05 °C. You get both accuracy and flexibility built into a small, durable package.

The lead wires of the 5606 are made of single-conductor enameled copper wire which prevents 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 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.

Are you performing calibrations or verifying the accuracy of sensors used in ovens or furnaces? The 5607 has been designed specifically for your application. Intended to be used in dry mediums only, the 5607 can be fully immersed over a temperature range of 0 °C to 450 °C. There isn’t another PRT on the market that can be fully immersed over this range and remain as stable and accurate (± 0.055 °C). The lead wire of the 5607 is shielded with braided stainless steel and connected to the transition junction with a strain relief spring.

If you need longer lead wire than the standard length, call one of our Application Specialists today for a free quote. They can also help you determine which readout and probe termination are best suited for your application or help you select the right calibration for your probe.
