1) Introduction
The OS836-Series high performance infrared thermometer boasts 30 to 1 field of view and -50 to 1550°C (-58 to 2822°F)
temperature range. This high performance 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 OS836-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.
Applications such as food preparation, safety and fire inspection, plastic molding, molten metals, asphalt, oil, rubber,
concrete and many more. The 30:1 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 black 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 OS836-Series below.
*Units in mm
Emissivity:
Most organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-set in the 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!

3.4 Operating Steps
1) Hold the thermometer by the handle grip and point it towards the surface to be measured.
2) Pull and hold the trigger to turn the thermometer on, the “SCAN” icon will appear and blink when
measurement starts.
3) The surface temperature being measured will be displayed on the LCD screen.
4) Release the trigger, the “HOLD” icon will appear and the reading will stay on the display screen.
5) The thermometer will automatically shut off 25 seconds after the trigger is released.
Note: If the thermometer is to be used in ambient temperature after a large temperature change wait 30 minutes for the
thermometer to adjust to ambient temperature.
The laser is designed for aiming only, it can be shut off while operating in shorter distances to save battery (Section 3.5.3).
3.5 Button function

3.6 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.
