1.2 About Wahl DHS520/520B Portable Thermometers
The
Wahl DHS520/520B
is a highly accurate, portable, short wavelength
infrared thermometer, designed to measure and display temperatures in the
range 550 to 3000°C/1022 to 5432°F. The thermometer can also measure
and display these temperatures in Kelvin and °Rankine.
The target temperature is measured and displayed in four simultaneous
measurement types: ‘Peak’, ‘Continuous’, ‘Average’ and ‘Valley’. You can
choose which of these measurements is displayed in the internal viewfinder
display.
The wide angle (9°) field of view and the small (1/3°) measurement point ensure
that the target is defined clearly and accurately. The focus is continuously
variable from one meter to infinity. Auxiliary lenses are available, which provide
close focus capability.
The emissivity compensation setting can be controlled digitally, via the simple
to use, icon-based menu system, which is available at the touch of a button.
The operating waveband has been chosen specifically to minimize errors due
to uncertainty in emissivity, while eliminating the effects of atmospheric
absorption.
Both models feature RS232 serial communications, with simple configuration
of the available data output formats. The Wahl DHS520B variant also features
user-friendly ‘Bluetooth’ communications.
