Overview
The easy-to-use Fluke 561 combines the temperature measurement functions that professionals need for various heating, ventilation and air conditioning monitoring jobs, all in one tool. It provides both noncontact infrared (IR) and contact temperature measurements, replacing the need for multiple test tools.
Features
IR thermometer for quick measurements up close or at a distance
Single-point laser sighting
Easy emissivity adjustment for measuring pipes and ducts more accurately
Includes a Velcro pipe probe for super-heat and sub-cooling as well as other surface contact measurements
Also compatible with all standard mini-connector K-type thermocouples
MIN, MAX and DIF temperature readings
Lightweight (only 340 grams) and portable
Includes measurement guide
