Probe, Secon. PRT, 100 ohm,9in 90 deg Bend

If you want a very stable thermometer from –200 °C to 670 °C and are particular about the calibration, then look no further than our 5609 Secondary Reference PRT. Its short-term stability at the triple point of water is only ± 10 mK and its one-quarter inch (6.23 mm) diameter lets you get accurate measurements in only 100 mm of immersion. The 5608 is also a ± 10 mK probe at the triple point of water, but its one-eighth inch (3.18 mm) diameter gets you accurate measurements from –200 °C to 500 °C with only 80 mm (3.1 in) of immersion. With multiple sheath length options on both of these probes, and an optonal 90 ° bend at nine inches from the tip for dry-well applications, you can find the dimensions that are just right for your specific application.The 5608 comes with a one-eighth inch (3.18 mm) diameter sheath in lengths of 9 inches or 12 inches. The 5609 comes with a one-quarter inch (6.35 mm) diameter sheath in lengths of 12 inches, 15 inches, and 20 inches; or with a 6 mm diameter in lengths of 300 mm, 400 mm, or 500 mm.
