PALMER WAHL DHS520L1 High Precision Portable Infrared Thermometer

The Wahl DHS520L1 and DHS520L2 Series Heat Spy® models are high precision portable infrared thermometers, designed for accurate high temperature measurement in the range of 1022° to 5432°F (550° to 3000°C).
Features include Bluetooth® serial communications, optional data logger software on Mobile Phone or PC/Laptop, precise view of target spot with simultaneous digital display of temperature in the viewfinder, choice of operating and calculating modes, digital output and out of range alarms.
 
The measured temperature is displayed in four simultaneous modes: continuous, average, max, and min, with user selected mode for the viewfinder display. Temperature measurement resolution to 1°.
Accurate sighting is ensured by the clear, wide angle (9°) field of view and small, clearly defined (1/3°) measurement area. Focusing is variable from 1m to infinity, with close focus options available using auxiliary lenses. Emissivity compensation is provided via the icon based menu system.
