Product Overview: Fluke 561 Infrared & Contact Thermometer
Fluke FLUKE-561 Infrared & Contact Thermometer
The Fluke 561 IR Contact Thermometer is a versatile tool designed for industrial, electrical, and HVAC/R professionals. It combines non-contact infrared temperature measurement with K-type thermocouple capability for contact measurements, making it fast, efficient, and easy to use.
The 561 allows you to quickly scan large areas or small objects without shutting down equipment, making it perfect for measuring hot, moving, electrically energized, or hard-to-reach items. Use it to check motors, insulation, breakers, radiant heating, pipes, corroded connections, wires, and ducts—without needing a ladder.
The included flexible pipe probe is ideal for taking superheat or internal temperature readings. You can also use any standard K-type mini connector thermocouple probe, ensuring compatibility with thermocouples you already own.
Additional Features:
- Hook-and-loop pipe probe for superheat, subcooling, and ambient measurements
- MIN, MAX, and DIF functions for quick problem identification
- Lightweight at only 12 oz (340g) and easy to operate.
