Fluke calibration RTD Probe Handheld Digital Thermometer with 1 Input, ±0.05°C Accuracy, +160°C Max Temperature 1551A-12

Fluke calibration 1551A-12 RTD Probe Handheld Digital Thermometer is a portable, battery-powered instrument designed for precise temperature measurement and calibration in industrial and hazardous environments. It features a fixed RTD probe combined with an integrated digital display, capable of measuring temperatures up to +160°C with ±0.05°C accuracy, making it ideal for process calibration and maintenance tasks.

Powered by three AAA alkaline batteries, the thermometer supports approximately 300 hours of continuous use, providing reliable field service. Its intrinsically safe certification (ATEX) allows safe operation in explosive atmospheres, essential for chemical plants and other hazardous locations.

The unit supports high-resolution readings with 0.001°C increments and includes user-selectable resolution to enhance measurement detail. With optional internal data logging, it can store up to 10,000 time-stamped readings accessible via an RS-232 interface, simplifying data transfer for analysis and record keeping.

Compact and ergonomic, its dimensions are 114 mm in length, 57 mm wide, and 25 mm high, with a weight of 196 g, facilitating portability during site inspections and routine checks. The unit displays temperatures in both Celsius and Fahrenheit scales, catering to varied user preferences.

The thin-film 100Ω RTD sensor technology reduces susceptibility to drift compared to conventional wire-wound probes, enhancing long-term stability and repeatability critical for industrial calibration processes.

The thermometer is suitable for applications including calibration of process sensors in chemical plants, custody transfer temperature verification, quality control of ovens and chillers, and temperature validation in food processing lines. It is also useful for routine maintenance in electrical and mechanical systems.

The unit meets stringent standards including CISPR II Edition 5.0-2009 and EN61326:2006 Annex C, further affirming its suitability for demanding industrial environments. Users should note the minimum immersion depth for the sensor is 7 cm, with response times dependent on probe diameter.
