1) Introduction
The OS303-Series essential infrared thermometer boasts 12 to 1 field of view, -32 to 530°C temperature range and ±2%
accuracy above 0°C. This compact easy to use device is great for non-contact measurement of surfaces that are far away
and very high temperatures. Just aim, line up the laser, push the button and read the surface temperature in less than a
second. The OS303-Series is great for situations where the temperatures are so hot that being too close can become a
hazard or the location that needs measuring is hard to reach.
This units is great for applications such as asphalt, oil, rubber, concrete and many more. The 12:1 field of view, or distance
to spot ratio, allows for precise measurement even from a larger distance.
1.1 How it works
The sensor determines temperature by focusing the infrared energy that is radiated from an object. The focused energy is
converted into an electrical signal proportional to the energy emitted. A clean line of sight free of dust or mist is needed
between the sensor and the object. For increased ease and accuracy, the laser pointer makes aiming even more precise.
Measurement:
When taking measurement, point thermometer toward the object to be measured and hold the trigger. The object under
test should be larger than the spot size calculated by the field of view diagram below.
Field of View:
Field of view, or distance to spot ratio, is the size of an area that can be measured from a specified distance. As the distance
from the object increases, the spot size of the measuring area becomes larger. Make sure the target is larger than the unit’s
spot size. When accuracy is critical, make sure the target is at least twice as large as the spot size. Please see field of view
diagram for the OS303-Series below.
Emissivity:
Most organic materials and painted or oxidized surfaces have an emissivity of 0.95 (fixed for this unit). Inaccurate readings
will result from measuring shiny or polished metal surfaces. To compensate, cover the measured surface with masking tape
of flat black paint. Measure the tape or painted surface when the tape or painted surface reaches the material
temperature.

1.2 Caution
Infrared thermometer should be protected for the following:
- EMF (electro-magnetic fields) from arc welders and induction heaters.
- Thermal shock (caused by large or abrupt ambient temperature changes allow 30 minutes for unit to stabilize
before use).
- Do not leave the unit on or near objects of high temperature.
Warning: Do not point laser directly at eye or indirectly off reflective surfaces!

1) Changing temperature units
Press “Temperature unit switch” button to toggle between Celsius and Fahrenheit.
2) Turning laser On/Off
Press “Laser On/Off” button to toggle laser on and off.
3) Turning backlight On/Off
Press “Backlight On/Off” button to toggle LCD backlight on and off.
4) Changing offset
Press and hold “Temperature unit switch” button for 3 seconds, this will enter the offset menu. Use the
“Laser On/Off” button to adjust offset up and use the “Backlight On/Off” button to adjust offset down.
Don’t press any buttons for 5 seconds to exit offset menu. When out of offset menu the word offset will
disappear from the bottom of the screen.
3.5 Locating a Hotspot:
To find a hot spot aim the thermometer outside the area of interest, then scan across with up and down motions until you
locate the hot spot. (please turn on the laser for accurate measuring).
4) Maintenance
1) Lens cleaning : blow off loose particles using clean compressed air. Gently brush remaining debris away with a moist
cotton cloth.
2) Case cleaning: clean the case with a damp sponge/cloth and mild soap.
Note: Do not use solvent to clean lens and do not submerge the unit into water or any other liquid.
