Fluke 52 II Dual Probe Digital Thermometer

Accurate, Robust Dual‑Input Temperature Measurement

Product Description Fluke 52 II Dual Probe Digital Thermometer

The Fluke 52 II is a professional dual‑probe thermometer engineered for precision temperature monitoring in industrial, HVAC, laboratory, and food‑safety applications. Its dual inputs allow simultaneous readings from two thermocouples, making it ideal for comparative measurements and temperature differentials. Encased in a splash‑ and dust‑resistant housing with a shock‑absorbing holster, the Fluke 52 II delivers reliable performance in the toughest environments.

Key Features Fluke 52 II Dual Probe Digital Thermometer

• Dual‑input capability: Measure two locations simultaneously and monitor temperature differences.

• Relative time‑stamped MIN, MAX, AVG: Records the time at which extreme and average values occur, aiding event analysis.

• Electronic Offset: Compensates for thermocouple error to maximize overall measurement accuracy.

• Thermocouple support: Types J, K, T, and E (plus N, R, S on 53 II B/54 II B models).

• Selectable units: Display in °C, °F, or Kelvin (K).

• Rugged design: Splash‑ and dust‑resistant casing with impact‑absorbing holster.

• Intuitive front panel: Simple controls for easy setup and operation.

• Extended battery life: Sleep mode for up to 1000 hours of typical use.

• Calibration‑safe battery door: Replace batteries without breaking the calibration seal.

• Hands‑free operation: Optional ToolPak mounts via magnets or hook‑and‑loop strap.
