OMEGA OS306-Series Performance Infrared Thermometer

Introduction

The OS306-series handheld digital IR thermometer is used for non-contact temperature measurement of metals, ceramics, graphite, etc. in temperature ranges between -50°C (-58 °F) and 1650°C (3002°F). This portable battery- powered unit displays the current temperature as well as minimum, maximum, average, and differential temperatures. Other features include an adjustable emissivity, alarm settings, and a single laser dot to help locate the target.
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 the field of view diagram for the OS306-Series below.

Emissivity: Most organic materials and painted or oxidized surfaces have an emissivity of 0.95. Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate adjust the emissivity setting to match the material using the emissivity table. Another option is to set the emissivity to 0.95 and cover the measured surface with masking tape or flat black paint. Then measure the tape or painted surface when it 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

Battery Installation and Basic Operation Locate the notches on the side of the unit’s handle and pull the front of the handle forwards as shown below (1,2). Attach a 9V battery (provided) to the black connector inside, be sure to connect the positive and negative sides to the corresponding terminals (3). Swing the front of the handle back upwards to close the unit (4).

Pull the trigger and the LCD display will turn on and display reading. Release the trigger to hold the last measured temperature reading. The display will shut off after 30 seconds of inactivity.
