Advanced applications and processes need specialized
tools like the Raynger
The Raytek 3i series of noncontact thermometers
measures surface temperature in places other
thermometers cannot. With a choice of spectral
responses, temperature ranges, laser sighting options
and on-board data logging capabilities, the Raytek 3i
meets the individual requirements of demanding users.

3i thermometer compensates for the energy
reflected by the background around the target.
Reflected background energy compensation
allows for accurate measurement even when the
area measured is reflecting energy from nearby objects
with higher temperatures; for example, inside a furnace. Varying
spectral responses, laser-sighting systems, and distance-tomeasurement spot ratios ensure the Raytek 3i temperature
measurements are precise.

Single Laser (L2, L3)
Single laser models are designed
for accuracy over distances and
pinpoint the center of the target
area with a bright laser spot. The
single laser L3 unit is equipped
Dual Laser (DL2, DL3)
The dual laser uses two laser
spots to indicate the diameter
of the target area measured.
Crossed Laser (CL2, CL3)
For precise measurement
of smaller targets, minimum
measurement spot is indicated
at the point the two laser
beams meet.
with a 4 milliwatt laser, providing
the brightest laser guide.
Models ending with L2 meet FDA Class II and IEC Class 2 requirements. Models ending with L3 meet FDA Class IIIa requirements.

Scope with Laser (SCL2)
Measure temperature at a distance

point, 3i scopes are parallax-free
and provide circular reticles for
pinpoint accuracy. To enhance the
sighting capabilities of the scope,
combine the scope with a laser
equipped model.
