Product overview: Fluke 712B RTD Calibrators

Fluke 712B RTD Calibrator provides highly accurate, easy-to-use, single-function RTD temperature calibration

Fluke 712B RTD Calibrator is a handheld, battery-operated instrument that measures and sources a variety of RTD types and resistances. It also includes an isolated channel to measure 4-20 mA whiles sourcing a temperature signal. It offers configurable 0% and 100% source settings for quick 25% linearity checks. It also provides linear ramp and 25% step auto ramp functionality based on 0% and 100% settings.

Add to that dual inputs, an easy to view backlit display, plus the ability to memorize settings at power down for easy restart make the 712B the ideal test tool for temperature calibration professionals who want a highly accurate, easy-to-use, single function RTD temperature calibrator.

Other useful features:

  • Dual inputs and backlit display for easy interpretation of measurements
  • Remembers power down settings to easily restart tests when powered up
  • Provides linear ramp and 25% step auto ramp based on 0% and 100% settings
  • Provides one-year and two-year specifications and traceable certification of calibration

1. Sensor inaccuracies not included.
2. Resolution: 0.1°C.
3. Read accuracy is based on 4-wire input. For 3-wire RTD measurements, assuming all three RTD leads are matched, add 1.0°C (Pt10 and Cu10), 0.6°C (Pt50 and Cu50), 0.4°C (Other RTD types) to the specifications.
4. Source Accuracy in source mode is based on 0.5 mA~3 mA (1.00 Ω~400.00 Ω), 0.05 mA~0.8 mA (400.0 Ω~1500.0 Ω), 0.05 mA~0.4 mA (1500.0 Ω ~4000.0 Ω), excitation current (0.25 mA for Pt1000 range).
5. Temperature Coefficient: ±0.05°C /°C for measure, ±0.05°C /°C (< 18°C or > 28°C) for source.
6. Supports pulsed transmitters and PLCs with pulse times as short as 5 ms.
