Fluke 1552A-12 RTD Thermometer -112 to 572F Digital measurement tool

Fluke 1552A-12 Reference Calibrator

The Fluke 1552A-12 is an intrinsically-safe reference calibrator designed for precise temperature verification. It covers a range from -112 to 572 degrees Fahrenheit with variable resolution down to 0.001 degrees. The unit includes 3-point NIST-traceable and NVLAP-accredited calibration for documented accuracy. Power is supplied by three included AAA batteries with an auto power-off function.

Technicians needing documented traceability

This calibrator suits professionals who require accredited calibration certificates and intrinsic safety ratings for hazardous environments. The 20-second response time supports efficient workflow in process and laboratory settings. Buyers who need a broader temperature span or faster settling times should evaluate alternative instruments. The fixed immersion depths of 70 mm wet and 120 mm dry define the probe insertion requirements.

Variable resolution to 0.001 degrees

The selectable resolution of 0.1, 0.01 or 0.001 degrees determines the measurement granularity available for critical reference work. This flexibility allows the operator to match display precision to the specific calibration task. Confirm that the minimum immersion depths of 70 mm in wet media and 120 mm in dry media are compatible with your test wells or baths before purchase.
