Infrared thermometer KIRAY 50 is a key tool to diagnose, inspect and check
any temperature, with the advantage of using “no-contact” technology.
You can safely measure surface temperatures of hot objects, dangerous or
difcult to access. Perfect tool to take temperature in a house, a garage, a
workshop, an ofce, a car, a kitchen etc...

Kit content
• Case holster with passer-by belt
• User manual
CE certication
This device meets with following standards’ requirements.
EN 61326-1: 2013 and EN 61326-2: 2013
5 - Trigger: it allows to measure temperatures. Press
the trigge: "scan" is indicated on the top left of the
screen. Release it, "hold" is indicated on the top left
of the screen and the last measurement is displayed.
Device automatically shut off after 10 seconds of
inactivity.

Important information
For correct measurements:
• Do not take any measurement on metal or shiny or
reective surfaces.
• Do not measure through transparent surfaces such
as glass, for example.
• Water vapor, dust, smoke, etc... may prevent correct
measurements because they obstruct the optical of
the instrument.
• Make sure that the target is larger than the size of
the laser sighting.
To avoid any inconvenience:
• Do not aim directly or indirectly (reection on
reective surfaces) the laser in the eyes.
• Change the batteries when the indicator blinks.
• Do not use the thermometer around explosive gas,
vapor or dust
• Do not leave the device with the lock on (lock
at the top right of the screen) because in this
conguration, the instrument does not turn
off automatically.
To prevent damage on your instrument or equipment
please carefully respect these conditions:
Maintenance
To install or change the 9 V battery, open the part near the
trigger and put it in the battery compartment.
Emissivity
Emissivity is a term used to describe the energy-emitting
characteristics of materials.
Most (90% of typical applications) 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 surface to be measured with
masking tape or at black paint.
Allow time for the tape to reach the same temperature as
the material underneath it.
Measure the temperature of the tape or painted surface.
See table below for values of emissivity of specic
materials:
Aluminum 0.30 Ice 0.98
Asbestos 0.95 Iron 0.70
Asphalt 0.95 Lead 0.50
Basalt 0.70 Limestone 0.98
Brass 0.50 Oil 0.94
Brick 0.90 Paint 0.93
Carbon 0.85 Paper 0.95
Ceramic 0.95 Plastic 0.95
Concrete 0.95 Rubber 0.95
Copper 0.95 Sand 0.90
Dirt 0.94 Skin 0.98
Frozen food 0.90 Snow 0.90
Hot food 0.93 Steel 0.80
Glass 0.85 Textile 0.94
Water 0.93 Wood 0.94
Fresh foodstuffs between 0 and 5 °C 0.90
Infrared thermometer, how does it works?
Infrared thermometers can measure the surface
temperature of an object. Its optic lens catches the
energy emitted and reected by the object.
This energy is collected and focused onto a detector.
This information is displayed as temperature.
The laser pointer is only used to aim at the target.
