Technical Data
Product Image Description
A yellow and black Fluke 561 IR thermometer with a pistol grip. The device features a lens for infrared measurement, a digital display showing "66.0 F", control buttons, and a laser sighting indicator.
Key features
- Contact and non-contact IR thermometer for measuring up close or at a distance, without a ladder.
- Measures temperature from -40°C to 550° C (-40°F to 1022°F).
- Works with all standard mini-connector type K thermocouples.
- Provides single-point laser sighting.
- Allows easy emissivity adjustment for measuring pipes and other shiny surfaces more accurately.
Product overview: 561 HVAC Infrared & Contact Thermometer
The Fluke 561 IR and contact thermometer meets the needs of most industrial and residential temperature applications. It combines temperature measurement functions essential for industrial, electrical, and HVAC/R professionals. The tool serves as an IR thermometer for non-contact measurements and offers K-type thermocouple capability for contact temperature measurement, providing a fast, efficient, and easy-to-use solution that saves time and effort.
Utilize the 561 IR for quick and efficient scanning of large areas or small objects, even without shutting down equipment. It enables instant measurement of hot, moving, electrically energized, and hard-to-reach objects. Applications include checking motors, insulation, breakers, radiant heating, pipes, corroded connections, and wires. Scan ducts and other difficult-to-reach objects from the floor, eliminating the need for a ladder.
The Fluke 561 includes a flexible pipe probe for measuring super-heat or internal temperatures. It also supports any industry-standard type K mini-connector thermocouple probe, allowing users to leverage existing investments in thermocouple probes.
Other useful features
- Features a fabric hook-and-loop fastener pipe probe for superheat, sub-cooling, and other contact and ambient measurements.
- Provides MIN, MAX, and DIF functions to help quickly identify problems.
- Weighs only 12 ounces (340 grams) and is extremely easy to use.
