The FLIR TG56-2™ and Fluke 64 MAX are two well-known mid-tier infrared thermometers. Both provide accurate non-contact temperature measurement, but they differ in focus. The FLIR TG56-2™ excels in precision and range with a 30:1 distance-to-spot ratio, adjustable emissivity, and readings up to 2372 °F. The Fluke 64 MAX delivers adequate performance in a rugged package, but is limited to a 20:1 ratio and 1112 °F maximum temperature.

❓ Q&A Section

Q: Which model is more precise at a distance?
A: The FLIR TG56-2™ leads with a 30:1 ratio, allowing smaller targets to be measured accurately from further away. The Fluke 64 MAX is limited to 20:1, which is serviceable but less effective for coatings or precision work.

Q: Which covers higher temperatures?
A: The FLIR TG56-2™ measures up to 2372 °F, more than double the Fluke’s 1112 °F limit. This makes FLIR more versatile for high-heat applications such as industrial coatings and furnaces.

Q: Which is more rugged?
A: The Fluke 64 MAX offers IP54 environmental protection and a rugged build. The FLIR TG56-2™ is IP20, prioritizing performance features over heavy-duty casing. Fluke is tougher, but the tradeoff is less measurement capability.

Q: How does accuracy compare?
A: Both models claim ±1 °C or ±1% in normal ranges. However, the Fluke 64 MAX widens to ±2–3 °C at colder extremes, while the FLIR TG56-2™ stays consistent with a wider overall range.

Q: Can M-Testco support both models?
A: Yes. M-Testco sells and certifies the FLIR TG56-2™ and provides NIST-traceable certification for the Fluke 64 MAX.
