Fluke Hart Scientific 1502, 1502A and 1504 Reference Thermometer Readouts for RTDs, PRTs and Thermistor Sensors

Fluke Hart Scientific 1502 and 1504 Reference Thermometer Readouts

Fluke Hart Scientific 1502A Reference PRT Thermometer Readout ( –200 °C to 962 °C)

The Fluke Hart Scientific 1502A PRT Reference Thermometer Display or Readout accurately measures the resistance of the Reference Thermometer probe and then converts the resistance to a temperature value using its built-in algorithms.  features accuracy up to ±0.006 °C (the 1504 is even more accurate, up to ±0.002 °C). In addition, it reads 100-ohm, 25-ohm, and 10-ohm probes, has a resolution of 0.001 °C across its entire range, and is the smallest unit in its class. It also has an optional battery pack for completely portable operation. 

Each Fluke Hart Scientific 1502A Reference Thermometer Readout is programmable to match a probe’s constants for maximum linearity and accuracy. All probe constants and coefficients are programmed through simple, front-panel keystrokes. Temperature is displayed in  °C,  °F, K, or resistance in ohms. 

Fluke Hart Scientific 1502A Works with Industrial Grade RTDs

For convenience, the Fluke 1502A reads the common industrial grade IEC-751 or “385” ALPHA RTD without any programming. Enter the actual R0 and ALPHA of the individual probe for increased accuracy. For maximum accuracy, use the ITS-90 formulas. The Hart 1502A accepts the subranges 4 and 6 through 11.  ITS-90 formulas reside in the 1502A's firmware. If your probe has been calibrated for any of the above subranges of the ITS-90, you simply enter the coefficients directly into your 1502A. 

RS-232/IEEE Interface Allows Automation for Data collection with the Fluke 1502A

Each Fluke 1502A Reference Thermometer Readout comes complete with an RS-232 interface for automation of temperature data collection, calibrations, or process control functions. An IEEE-488 interface is available as an option. 

Fluke Hart Scientific 1502A Features Front Calibration Calibration

The Fluke 1502A is calibrated digitally using the front-panel buttons. You never have to open the box to calibrate it. This calibration protocol further reduces the cost of the 1502A. It goes where you go and works the way you want it to. 

Fluke Hart Scientific 1504 Thermistor Readout

If you need more accuracy in a limited temperature range, the Fluke Hart 1504 Temperature Readout gives it to you as a thermistor readout. Thermistors are less fragile than PRTs and less likely to be impacted by mechanical shock. Thermistors are more sensitive to temperature, have faster response times, and come in many shapes for different applications.  Typical accuracy of Hart 1504 is ±0.002 °C with a resolution of 0.0001 °C. The Fluke 1504 works with any Thermistor Temperature range.

Get Real-Time Data Acquisition with the Fluke Hart Scientific 9934 Logware/Software 

With the Fluke Hart Scientific 9934 LogWare, both the 1502A and 1504 Temperature Reference Readouts may be used for real-time data acquisition. You can collect data and analyze it graphically or statistically. Additionally, both the 1502A and 1504 may be used as reference thermometers with the Fluke MET/TEMP II software.

Portable Field Applicationsfor the Fluke1502A and 1504

Want to take your Fluke 1502A or 1504 on the road? No Problem! Specify Hart's 9320A Battery Pack for between charge operation of 36 hours allowing the portability you require.

Fluke 1502A, 1504 and Temperature Probes All have Calibration Reports Available  

Each Fluke Hart Scientific 1502A and 1504 and its accompanying probe (probes sold separately) have their own individual calibration reports. Overall system error can be calculated from the individual errors, rendering the added cost of system data unnecessary. However, for those requiring it, system data is available at two or more temperatures of your choice. (See Calibration Model 1929-X )
