geo FENNEL FIRT 800-Pocket Infrared Thermometers
Product Information
The geo-FENNEL FIRT 800-Pocket is an infrared thermometer that is suitable for non-contact measurements with a laser dot. It is designed for quick measurements of surfaces that are difficult to reach, moving or rotating, electrified, or hot. The energy collected from the surface measured is transferred into a temperature reading. The instrument is not suitable for measuring the surface temperature of shiny or polished surfaces and cannot measure through glass or other transparent materials. The instrument comes with a battery, case, and manual.
Product Usage
To use the geo-FENNEL FIRT 800-Pocket, follow the steps below:
- Switch on the instrument by pressing the measuring trigger button.
- Point the laser pointer at the surface to be measured.
- Press the measuring trigger button to take the temperature reading.
- Use the q button to turn on the illumination if needed.
- Use the p button to turn on the laser pointer if needed.
- Use the MODE button to navigate the menu and set EMS, HAL, LAL, C/F, MAX/MIN, and LOW values.
- To switch off the instrument, press and hold the measuring trigger button for 3 seconds.
- If the battery needs to be replaced, open the battery compartment cover and replace it with a new one.
Note: The instrument can be used in various industries such as food industry safety and fire inspectors, molding industry, road building, screen printing, dryer temperature, and fleet maintenance. Please read the manual carefully before use and follow all safety instructions to ensure proper use and reliable operation of the instrument.

OPERATION
SWITCH INSTRUMENT ON/OFF
Pull the measuring trigger to switch instrument on. After 7 seconds it
automatically switches off if no other key has been used. There is no special
key to switch off the instrument.
CARRYING OUT MEASUREMENTS
Hold the instrument by its handle and point towards the area to be measured.
Pull and hold the trigger to turn the instrument on and carry out measuring
process. Release the trigger and HOLD will be displayed indicating that
reading is held for about 7 seconds. If no other button is used instrument
will automatically switch off after 7 seconds.
LASER POINTER
For exact targeting the area to be measured switch on laser pointer with
button during HOLD mode. The laser icon will be displayed.
Please take care to the explanations given regarding Distance: Spot-Ratio.
ILLUMINATION
In bad light conditions the illumination can be switched on with button
during HOLD mode.
EMISSIVITY
The emissivity is a term used to describe the energy-emitting characteristics
of a material. Most (90 % of typical applications) organic materials and
painted or oxidized surfaces have an emissivity of, 95 (pre-set in the unit).
Inaccurate reading will result from measuring shiny or polished metal
surfaces. To compensate, cover the surface to be measured with masking tape.
Press MODE button (5) and „E“ starts blinking. The required emissivity can be
set with q / p buttons.
EMISSIVITY VALUES
| Material | Emissivity | Material | Emissivity |
|---|---|---|---|
| Asphalt | 0,90 – 0,98 | Cloth (black) | 0,98 |
| Concrete | 0,94 | Human skin | 0,98 |
| Cement | 0,96 | Lather | 0,75 – 0,80 |
| Sand | 0,90 | Charcoal | 0,96 |
| Earth | 0,92 – 0,96 | Lacquer | 0,80 – 0,95 |
| Water | 0,92 – 0,96 | Lacquer | 0,97 |
| Ice | 0,96 – 0,98 | Rubber (black) | 0,94 |
| Snow | 0,83 | Plastic | 0,85 – 0,95 |
| Glass | 0,90 – 0,94 | Timber | 0,90 |
| Ceramic | 0,90 – 0,94 | Paper | 0,70 – 0,94 |
| Marble | 0,94 | Chromium ox. | 0,81 |
| Plaster | 0,80 – 0,90 | Copper ox. | 0,78 |
| Mortar | 0,89 – 0,91 | Iron ox. | 0,78 – 0,82 |
| Brick | 0,93 – 0,96 | Textiles | 0,90 |
Note:
In case of large fluctuation of temperature (if instrument has been stored in
cold area and is to be used in warm area – or the other way round) wait some
minutes before carrying out measurements.
DISTANCE (D) : SPOT SIZE (S)
The distance:spot ratio is important for evaluation of the area measured. The larger the distance from the object the larger the area measured. Switch on the laser pointer for increasing target accuracy.
Note:
The target must be larger than the instrument’s spot size. The smaller the
target the shorter the distance should be.
