Produktöversikt: Secondary PRT with Calibration Options - 5608 and 5609

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 Inconel™ sheaths and are made using a special manufacturing process, giving them great precision 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.

As standard, each probe includes its resistance value at the triple point of water. If calibration is desired, you can order a NVLAP-accredited calibration from our laboratory; lab code 200348-0. On the report of calibration, you’ll get the test data and the ITS90 calibration coefficients that you can easily input into any Fluke Calibration thermometer. If you order your probe with an smart connector, we’ll program the coefficients directly into your connector, which loads the coefficients for you when you plug it into our 1524 Handheld Thermometer.

Calibration
 
 
 
[1] Includes short-term repeatability and 100 hr drift. Calibration will add additional uncertainties.

[2] Three thermal cycles from min to max temp, includes hysteresis, 99.9 % confidence (k=3)

[3]After 100 hours at max temp, 99.9 % confidence (k=3)

[4] Temperatures outside this range will cause irreparable damage. For best performance, transition junction should not be too hot to touch.

[5] Per ASTM E 644
Calibration Uncertainty for  NVLAP-accredited† calibration
TemperatureExpanded Uncertainty (k=2)

Note: Calibration uncertainties depend on the uncertainties of the lab performing the calibration. Subsequent calibrations of this probe performed with different processes, at different facilities, or with changed uncertainty statements may state different uncertainties. †Lab code 200348-0
