Fluke 52 II Dual-Input Digital Thermometer
Model: 52 II
The Fluke 52 II is a dual-input digital thermometer that accepts Type K, J, T, and E thermocouples directly. Its built-in T1-T2 differential display makes it ideal for comparison-method thermocouple calibration in industrial settings. Measuring from -200 to +1000°C with ±1°C accuracy at ambient, it is a fast, rugged field instrument. Common in HVAC commissioning, furnace verification, and temperature process checks across Thai manufacturing.

Frequently Asked Questions
Can the Fluke 52 II be used as a reference for thermocouple calibration?+
Yes for field comparison work, but only if the Fluke 52 II itself has a current NIMT-traceable calibration certificate. Its uncertainty must be included in the calibration uncertainty budget.
Is ±1°C accuracy sufficient for GMP applications?+
Not for processes requiring uncertainty ≤ ±0.3°C such as lyophilizers or pharmaceutical stability chambers. Those require an SPRT or calibrated PT100 as the reference standard.
What is the T1-T2 function useful for?+
It instantly displays the temperature difference between two measurement points — useful for heat exchanger inlet/outlet differential without manual subtraction.
