A INTENDED USE OF INSTRUMENT

IR-Thermometer FIRT 550-Pocket is suitable for non-contact measurements with laser dot. Quick measurements of surfaces that are difficult to reach, that are moving or rotating, that are electrified or that are hot. The energy reflected from the surface measured is transferred into a temperature reading.
The instrument is not suitable for measuring surface temperature of shiny or polished surfaces (see emissivity). The instrument cannot measure through glass or other transparent materials. It will measu- re the temperature of the glass instead. Steam, dust and smoke can prevent from exact measurement as they would obstruct the instrument’s optic.

B APPLICATION

Food industry safety and fire inspectors, moulding industry, road building, screen printing, dryer tempe- rature, fleet maintenance.

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.

OPERATION C

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 ▼ / ▲ buttons.

H 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

TEMPERATURE UNITS

Measured temperatures will be indicated in °C or °F. Open handle grip and switch from °C to °F. Close handle grip again.

MAX TEMPERATURE INDICATION

The display shows the maximum temperature measured during measuring procedure (from pulling to releasing the trigger (display icon 8).

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
