High Temperature Handheld Infrared Thermometer
RAYTEK® RAYNGER® SERIES
3i Plus
Stronger Simpler Safer

Raynger® 3i Plus
The Raytek® Raynger 3i Plus infrared
thermometer is a new generation of portable
products designed in accordance with industry
standards to meet process performance
requirements in hot environments. It combines
high-precision, superior Distance-to-Spot
(D:S) ratio with high accuracy and a robust
feature set that provides excellent temperature
measurement solutions for process temperature
detection and fault previewing.
The 3i Plus has been ergonomically designed
with comfort grip to ensure firm grasp by the
operator. Additional features for enhanced
Stronger
ease-of-use include Red Dot sighting
technology for accurate targeting when
high temperature targets are not
visible using laser sighting alone.
DataTemp® Windows PC software
supports real-time communication,
data storage, graphing and
analysis. This innovative
thermometer includes a mobile app for quick
data transfer and collaboration, and can be
used temporarily as an online thermometer.

Laser Sighting Options
Dual Laser
For precise measurement
of smaller targets, the
measurement spot is
indicated at the point the
two laser beams meet.
Red Nose
High temperature resistant
plastic material nose features
temperature sensor inside. If
sensor is measuring critical
temperature, alarm is given
in the LCD of the 3i Plus.
Red Dot Sighting
When the target is bright
or red hot, the laser
cannot be seen. The Red
Dot light in the scope
highlights the area with a
red light indicating where
the temperature is being
measured.
Benefits:
Stronger – Users will benefit
from a rugged design, extended
battery life and faster exposure
time.
Simpler – Increases operator
efficiency, minimizing labor
and maintenance cost.
Safer – Reduces risks of costly
accidents and ensures operator
safety. Reduces the risk of sensor
overheating while minimizing
repair costs and risk of process
temperature failures.
