Fits compact precision thermometer readout where you need a Fluke Calibration Tweener — 1502A for PRT/SPRT or 1504 for thermistors — with lab-grade accuracy in a small benchtop package.
Key advantages
- Models — 1502A (PRT) and 1504 (thermistor) Tweener readouts
- Accuracy — 1502A up to ±0.006 °C; 1504 up to ±0.002 °C (typical published)
- Resolution — 1502A 0.001 °C; 1504 0.0001 °C
- Ranges — 1502A −200 to 962 °C (probe-limited); 1504 thermistor ranges
- I/O — RS-232 standard; IEEE-488 optional; 115/230 VAC or optional 12 V DC
Typical applications
- Secondary lab PRT readout (1502A).
- High-resolution thermistor baths (1504).
- Portable Tweener carts with optional DC board.
Selection guide
- Model — 1502A PRT vs 1504 thermistor
- Probes — Ro 10/25/100 Ω vs thermistor curves
- Characterizations — ITS-90 / CVD vs Steinhart-Hart
- Interface — RS-232 vs IEEE-488
Common mistakes
- Buying 1504 for SPRT work — use 1502A.
- Ignoring probe-limited temperature range.
- Skipping warm-up before accuracy-critical work.
When to RFQ / what to tell us
