The Fluke 1551A-20 is a handheld digital thermometer designed for precision temperature measurement in hazardous and industrial environments. Equipped with a single 100 Ω thin-film RTD input and a 508 mm (1/4 in × 20 in) probe, it covers a temperature range of –50 °C to +160 °C (–58 °F to +320 °F) with accuracy of ±0.05 °C (±0.09 °F). The device is certified intrinsically safe (ATEX/IECEx compliant) for use in potentially explosive atmospheres. Its rugged stainless-steel probe and rotating, backlit display support field calibration, thermometer verification, and process instrumentation checks.

Core Capabilities of the Fluke Digital Thermometer, Handheld

  • Single-channel RTD input supports direct measurement of thin-film sensors.
  • –50 °C to +160 °C range with ±0.05 °C full-range accuracy for traceable precision.
  • Intrinsically safe certification (Ex ib IIB T4 Gb) allows use in explosive-gas zones.
  • Rotating backlit LCD display improves readability in varied orientations.
  • Compact handheld design simplifies field calibration and verification tasks.
  • Stainless-steel probe construction resists corrosion and supports industrial use.

Planned for High-Integrity Calibration and Verification

This digital thermometer is desigend for harsh calibration environments where accuracy, safety, and reliability are imperative. The built-in RTD sensor and measurement system are calibrated as a unit, reducing systematic error and improving measurement traceability. The intrinsically safe design ensures safe deployment in zones where explosive atmospheres may be present, while long battery life supports extended field operation.

Versatility in Applications

  • Calibration of temperature sensors in petrochemical and oil & gas facilities.
  • Verification of thermometers in pharmaceutical and food-processing plants.
  • Routine check of process instrumentation in hazardous-area environments.
  • Field measurement of fluid, gas, or ambient temperatures in industrial plants.
  • Mobile temperature audits and maintenance work in explosion-risk zones.
