Fluke 52-2B Dual-Input Thermometer

The Fluke 52-2B is a dual-input thermocouple thermometer built for HVAC technicians, field engineers and lab staff who need simultaneous readings from two probes. Its 1.8 in backlit LCD shows both channels at once, and the included NIST-traceable certificate supports regulated workflows from day one.

Wide Range Across Six Thermocouple Types

Type K covers -200 to 1,372 Degrees C, Type J covers -210 to 1,200 Degrees C, and Type T covers -250 to 400 Degrees C for cryogenic work. Type E spans -150 to 1,000 Degrees C, Type N spans -200 to 1,300 Degrees C, and Types R and S reach 0 to 1,767 Degrees C for high-temperature processes. Accuracy is +/- 0.05 Percent + 0.3 Degrees C on all supported types.

Handheld Build with Max/Min/Avg Logging

Three AA cells power the unit for extended field sessions without mains access. The rugged housing withstands daily transport in a tool bag, while the backlit display remains readable in dim plant rooms. Max, Min and Average recording captures temperature trends automatically, reducing manual note-taking during long test runs.

Questions about this item

Will the Fluke 52-2B read sensors from my older K-type probe kit?

The meter accepts Type K thermocouples across its full -200 to 1372 degrees C range, so existing K-type probes will work without adapters.

How can I confirm the Fluke 52-2B is measuring within its rated accuracy after power-up?

Compare the displayed reading against a known reference source; the instrument is specified at +/- 0.05 percent + 0.3 degrees C and ships with a NIST-traceable certificate.

Does the Fluke 52-2B come with thermocouple probes or must they be purchased separately?

The package includes the meter, three AA batteries and a NIST-traceable certificate; thermocouple probes are not included and must be bought separately.
