(100 mm minimum immersion) 0.01 short-term stability > Calibration not included, NVLAP-accredited calibration optional, lab code 200348-0Dry-well reference with 90 Ѱ bend > If you want a very stable ther-mometer from 200 ְC to 670 C and are particular about the calibration, then look no further than our 5609 Secondary Refer- ence PRT. Its short-term stability at the triple point of water is only б 10 mK and its one-quar- ter inch (6.23 mm) diameter lets you get accurate measurements in only 100 mm of immer- sion. 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 і200 C to 500 аC 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.When looking for improved response time and reduced stem effect in shallow immersion, look for small diameter probes, because the measurement error called stem effect is caused by the diameter of the stem rather than the length of the stem.Both of these probes have InconelЙ sheaths and are made using a special manufacturing process, giving them great preci- sion over a wide temperature range. The sensors for these probes are reference-grade platinum and feature four-wire connections with less noisy measurements than two-wire counterparts.These probes come with a certificate of compliance to ensure they meet their specifica- tions. If youd like, you can also order a NVLAP-accredited cali- bration from our laboratory, lab code 200348-0. On the report of calibration, youҒll get the test data and the ITS-90 calibration coefficients that you can easily input into any Hart thermometer. If you order your probe with an INFO-CON connector, well program the coefficients directly into your connector, which loads the coefficients for you when you plug it into our 1522 Hand- held Thermometer.Call today for your free quote. size="-1">
