Fluke 561 Infrared Thermometer Bundle, -40 °C Min, +550 °C Max, ±1 % Accuracy, F, °C, Fahrenheit Measurements

Fluke Infrared Thermometer Bundle, ±1% Accuracy, 12:1 Distance to Spot Ratio - 2558118

This infrared thermometer bundle is a portable non-contact temperature gun for HVAC and industrial diagnostics, designed to measure surface temperatures quickly across a wide range. It is suitable for field technicians and engineers who need fast spot readings and supplementary probe-based contact measurements in mechanical, electrical and automation settings.

Features & Benefits

• Measures from -40 to 550°C for broad-temperature tasks
  Resolution 0.1°C enables fine-grained temperature discrimination
  Distance-to-spot 12:1 allows safer long-reach readings
  Adjustable emissivity three-position selector for varied surfaces
  Response time 500 MS delivers near-instantaneous readings
  Powered by AA batteries with 12 h runtime for extended field use

**Applications**

• Suitable for fault-finding on motors and bearings
  Ideal for checking HVAC duct and valve temperatures
  Used for electrical panel thermal surveys from a distance
  Can be used for temperature verification during automated process checks
  Used with insulation and surface emissivity adjustments in fabrication

How does the laser sighting behave in warm environments?

The single-point laser turns off automatically when ambient temperature exceeds 40°C to prevent inaccurate targeting.

Can I Record maximum and minimum temperatures during a scan?

Yes
the instrument displays current, MAX, MIN and differential temperatures and holds readings for 7 seconds.

Which thermocouple probes are compatible with the mini-input?

Industry-standard type K mini-connectors plug into the mini thermocouple adapter input for contact measurements.

What optical and spectral characteristics affect measurement on varied materials?

The device uses an 8 μm–14 μm spectral band and an emissivity range selectable for low, medium or high emissivity to improve surface accuracy.

What environmental limits affect its operation and storage?

It operates between 0°C and 50°C and can be stored between -20°C and 65°C with 10%–90% non-condensing relative humidity below 30°C.
