PRESS RELEASE : Long Flexible Small Diameter Thermistor Brings High Accuracy To Harsh Environments

AMERICAN FORK, UT - Hart Scientific, a division of Fluke Corporation and a world leader in temperature calibration products and services, announces the addition of the model 5611T PTFE Probe to its line of secondary reference thermistors. Its PTFE-encapsulated tip, the thickest part of the thermistor, measures only 3 mm in diameter. Its flexible four-wire lead is PTFE-insulated and extends another 6 meters (20 ft).

The flexibility, length and chemical resistance of the 5611T make it a practical solution to many problems experienced in bio-pharmaceutical and other industries with harsh chemical environments. The probe’s calibration and unique construction allow ± 0.01 °C uncertainty readings to be taken quickly in either deep or shallow immersion.

The 5611T PTFE Probe is available for a US list price of $565, and deliveries are two weeks A.R.O. For more information, contact Hart Scientific at 800-GET-HART (801-763-1600 internationally), visit their website at, or email
