Fluke Hart Scientific 5650 5611A & 5611T Thermistor Resistance RTD Temperature Detector/Sensors

Hundreds of thousands of thermistors are sold every year, but only a few have the stability necessary for use as high-accuracy thermometry standards. If you're looking for economical lab-grade thermistor probes for accurate work across a narrow temperature range, Hart's 5650, 561A, and 5611T Secondary Reference Series thermistor probes are the most stable, most repeatable, most accurate thermistor temperature detector/probe/sensor available..

Fluke Hart Scientific 5650 5611A 5611t & 5665 RTD Thermistor Temperature Probe/Detectors Datasheet

Fluke Hart Scientific 5650 ~ 5611A ~ 5611T ~ 5665 Thermistor Secondary RTD Reference Detector-Thermometers

The Fluke Hart 5650 and 5611 thermistors temperature sensors are available in a variety of sheath materials appropriate for your specific application. In addition to our metal-sheathed probes, we offer flexible Teflon encapsulated and silicone coated thermistors that have smaller tips and can measure those places where even a metal-sheathed thermistor can't reach. 

Hart's Higher Performance Thermistor RTD Resistance Temperature Probes  

Hart's5650, 5611A 5611T and 5665 RTD Secondary Reference Thermistors have small diameters and very small sensing elements, which means they require far less immersion than a PRT to avoid errors caused by stem effect. Self heating is usually negligible, giving them an advantage when taking measurements in air. Their small size also improves response time, allowing measurements to be taken more quickly. If your application involves frequent handling, you'll be especially interested to know thermistors are less susceptible to mechanical shock than PRTs. The bottom line may be better accuracy in fieldwork. 

Thermistor RTDs with High Base Resistance Help Achieve Greater Accuracy

Additionally, higher base resistance and larger resistance coefficients make it easier to achieve precision readings with thermistors, so better resolution and accuracy are possible for a lower cost. All of these thermistors have a negative temperature coefficient of resistance (NTC). For additional information about thermistors, please see “Thermistors: the under-appreciated temperature standards” in our current catalog.

Fluke Hart Temperature Readouts Compliment the Temperature Calibration  

These probes come in a complete assembly ready for use, and each works well with the uncertainties of our thermometer readouts: the Hart 1504 Tweener, the 1523 and 1524 Handheld Thermometers, the 1529 Chub-E4, the 1560 Black Stack, and the 1594A and 1595A Super-Thermometers. These probes provide most accurate readings when coupled with a 2563 Standards Thermistor Module or 1590 Super-Thermometer, but they are most portable when used with a handheld Reference Thermometer.

Fluke Hart's 5650 5611A 5611T & 5665 Provide Cal-Lab Level Calibrated Accuracy 

What's more, the Hart 5650 5611A 5611T & 5665 Secondary Reference ThermistorsRTDs are accurate to ± 0.01 °C and cover the temperature range of 0 °C to 100 °C. They come with a NIST-traceable calibration and a resistance-versus-temperature table printed in 0.1 °C increments that can be interpolated to 0.0001 °C. NVLAP accredited calibrations as single thermistors or as systems combined with their readouts, are also available. No other sensors can match the accuracy and price combination of these high-accuracy thermistor probes. Try one and you'll agree.

Fluke Hart 5650 High Performance RTD Thermistor Temperature Immersion Probe

Fluke Hart 5611A Silicon Coated Bead Thermistor  RTD temperature Sensor

With a diameter at the tip of just 1.5 mm (0.06 in), the 5611A's tip has the smallest diameter of any of our secondary reference thermistors and can fit nearly anywhere. Its faster response time, flexible sheath, and silicone coating make the Fluke Hart 5611A great for use in many applications. However, applications involving silicone oil could damage the thermistor and should be avoided. 

Fluke Hart 5611T Teflon Encapsulated Thermistor RTD Temperature Sensor/Probe

Hart's 5611T is an especially versatile Teflon coated ThermistorTemperature Probe. With a Teflon encapsulated tip that is just 3 mm (0.12 in) in diameter and a Teflon coating that makes it impervious to most liquids, the Teflon protected Thermistor Temperature Probe assembly is handy for measuring in a wide variety of applications, including bio-pharmaceuticals. It's even immersible to nearly 20 feet and flexible enough that you could roll it up into a ball in your hand if you wanted to!  The 5611T's thermistor bead is encapsulated in a Mylar sleeve that is encapsulated inside a Teflon sleeve. The Teflon sleeve is then melted around the Teflon-insulated cable, forming a moisture-proof seal. 

Fluke Hart 5665 Minature Thermistor RTD Immersion Probe

At only 3.2mm in diameter, the Hart 5665 miniture immersion probe, protected by a stainless steel jacket, fits into the smallest and tightest places imaginable. The low thermal mass alows faster response times and less immersion time.
