OMEGA OS303-Series Essential Infrared Thermometer

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 unit 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.
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 the measurement, point the 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.

Emissivity Table:

Caution Infrared thermometer should be protected for the following:

• EMF (electromagnetic fields) from arc welders and induction heaters.
• Thermal shock (caused by large or abrupt ambient temperature changes allow 30 minutes for the 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!

Operating Instructions:

1. Changing temperature units
   • Press the “Temperature unit switch” button to toggle between Celsius and Fahrenheit.
2. Turning laser On/Off
   • Press the “Laser On/Off” button to toggle the laser on and off.
3. Turning backlight On/Off
   • Press the “Backlight On/Off” button to toggle the LCD backlight on and off.
4. Changing offset
   • Press and hold the “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 the offset menu. When out of the offset menu the word offset will disappear from the bottom of the screen.
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).

Maintenance

1. Lens cleaning: blow off loose particles using clean compressed air. Gently brush the remaining debris away with a moist cotton cloth.
2. Case cleaning: clean the case with a damp sponge/cloth and mild soap.
3. Note: Do not use solvent to clean the lens and do not submerge the unit into water or any other liquid.
