The new 5606 and 5607 Full Immersion PRTs from Fluke's Hart Scientific Division 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 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.
