Product overview: Fluke Calibration 1502A/1504 Thermometer Readout

Precision thermometer readouts for laboratory and field use

1502A Tweener PRT Readout

The Fluke Calibration 1502A Tweener offers precision temperature measurement with:

  • Accuracy up to ±0.006 °C
  • Resolution of 0.001 °C across the entire range
  • Compatibility with 100-ohm, 25-ohm, and 10-ohm RTD probes
  • Smallest unit in its class, ideal for field or bench use
  • Optional 9320A Battery Pack for full portability

Advanced Features

  • Programmable to match a probe’s constants for maximum linearity and accuracy
  • Displays temperature in °C, °F, K, or resistance in ohms
  • Reads standard industrial IEC-751 / “385 ALPHA” RTDs with no programming required
  • Accepts ITS-90 subranges 4 and 6–11, with formulas built into firmware
  • Calibration is done digitally via front-panel—no need to open the device
  • Comes with RS-232 interface; optional IEEE-488 interface available

1504 Tweener Thermistor Readout

Need higher precision in a narrower temperature range? The Model 1504 Tweener offers:

  • Accuracy up to ±0.002 °C
  • Resolution of 0.0001 °C
  • Designed specifically for thermistors—more robust, shock-resistant sensors with faster response times
  • Ideal for applications requiring high sensitivity and reliability in limited temperature spans

Calibration and Probe Integration

  • Each Tweener and its compatible probe (sold separately) include individual calibration reports
  • System data is available upon request at two or more temperatures for high-precision needs (Calibration Model 1929-X)
  • Users can calculate system accuracy using individual device specifications—no need to purchase system-level data unless required

Software Compatibility

Enhance your workflow with Fluke software tools:

  • 9934 LogWare: Real-time data acquisition, graphing, and analysis
  • MET/TEMP II: Use Tweeners as reference thermometers for automated calibrations

Optional Battery Pack

Take your Tweener on the road with the 9320A Battery Pack:

  • Provides up to 36 hours of portable operation between charges
  • Perfect for fieldwork or locations without direct power access
