New full immersion probes from Hart Scientific are designed to perform in extreme environments *Probes, lead wires and junctions withstand entire temperature range* EVERETT, Wash. – The Hart Scientific Division of Fluke Corporation has introduced new full immersion platinum resistance thermometer (PRT) probes designed to perform in extreme environments. The Hart Scientific 5606 and 5607 Full Immersion PRTs are designed to perform in “full immersion” applications where both the transition junction and the lead wires must withstand temperatures covering the entire operating range of the probe. Such applications can include calibration or validation of sensors used in laboratory or bio freezers, walk-in refrigerators, autoclaves, ovens, stability test chambers, furnaces or incubators. The Hart Scientific 5606 has a temperature range of -200 °C to 160 °C, while the 5607 has a range of 0 °C to 450 °C. The 5606 is only 2 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, users need not worry about calculating minimum immersion depth and can immerse the entire probe, transition junction, and lead wires in either non-corrosive liquids or dry mediums. 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 a 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. The 5607 has been designed specifically for performing calibrations or verifying the accuracy of sensors used in ovens or furnaces. Intended to be used in dry mediums only, the 5607 can be fully immersed in dry mediums 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 (± 0.05 °C). The lead wire of the 5607 is shielded with braided stainless steel and connected to the transition junction with a strain relief spring. The Hart Scientific 5606 Full Immersion PRT has a U.S. list price of $385; the 5607 Full Immersion PRT has a U.S. list price of $465.
