General description
The infrared thermometer 8895 is a measuring instrument for contact less temperature measurement. This thermal measurement principle is
ideally suitable for moving parts, electrically live parts, poisonous and sterile objects, where a conventional contact temperature measurement
method is not possible. The special features of the device are its fast response time and high temperature measuring range.
Theaiminglasergunprovidedinthedeviceshowsthecentreofthemeasuringobjectandsimpliesmeasurementsincaseofdistantobjects.
The accurate optics has an aperture ratio of 12:1.
The Data-Hold function enables short-term storage of measured values. In addition, the device is also provided with °C/°F-conversion.
With the adjustable emission level, the optical characteristics of the measured object are taken into account and exact results of measurement
are also achieved for critical materials.
The robust, handy pistol casing and big LC display with illuminated background offer optimal ergonomics with simplest usage.

2.2
Product-specicsafetyinstructions
!
Das Messgerät eignet sich aufgrund der berührungslosen Messverfahrens ideal zur Messung an kritischen Stellen, zum Beispiel an:
• Rotating shafts or moving work pieces
• Very hot or very cold objects
• Electrical parts under energised condition
• Unhealthy, poisonous or sterile materials
In should be noted that in the vicinity of such measuring points, often high hazard potential exists for the user or any third person. Hence, it
is necessary to exhibit a sensible behaviour and be more cautious. The relevant safety regulations shall be dully followed.
2.3 Precautions for Laser beam
!
Neverfocusthelaserbeamdirectlyorindirectly(e.g.throughreectivesurfaces)ontheeyesofhumanbeingsoranimals.Laserradiation
can cause permanent damage to the eyes. The laser beam must be de-activated during measurements near creatures. The instrument
should not be used by children.

2.4 Intended applications
!
The intended applications cover contact less measurement of temperature from -40 °C to +816 °C. For power supply, only two 1.5 V bat-
teries of type Mignon AA, IEC LR6 or equivalent are to be used. The operation is allowed only under dry environment conditions, contact
with moisture should be essentially avoided. A measurement under unfavourable environment conditions is not allowed. Unfavourable
environment conditions are: Dust and combustible gases, steam or solvents, thunderstorms as well as thunderstorm conditions like strong
electrostaticeldsetc.

3 Steps to eliminate measuring errors
Please take care of the following instructions while using the instrument:
• Avoid using the device in the vicinity of electrical welding sets, induction heaters, transmission equipment, frequency converters, and
otherstrongelectromagneticelds.
• After any abrupt change in temperature, the device should be left out for 15 minutes before using so that it can stabilise itself to the
new environment temperature.
• Do not expose the equipment to high temperatures for a long time.
• Avoid dusty and humid environment conditions. After usage, store the device in the storage bag to avoid contamination of the lens.
Consider technical facts of the measuring procedure to obtain exact results of measurement, particularly the relationship of measuring
spot size with respect to distance and the information for adjustment of emission value.

4.1
Measuring spot size
In order to achieve exact results from measurements, the measuring object must be bigger than the measuring spot of the infrared ther-
mometer. The measured temperature is the average temperature of the object surface. Smaller the object, shorter should be its distance
from the thermometer.
The exact measuring spot size can be decided from the diagram shown below. This diagram is also shown on the side of the device.

5.4 Temperature measurement
For measuring temperatures, hold the infrared thermometers with the opening of the infrared sensor pointing towards the object to be
measured and then press the trigger. The currently determined value of temperature appears on the LC-Display [3].
If the trigger is released now, the determined temperature value [3] shall be displayed for approximately 10 seconds. During this period,
the sign „Hold“ [8] appears on the display. After this, the device turns off by itself to save on the battery power.
TRIGGER
To localise the hottest point on the object to be measured, the infrared thermometer 8895 can be pointed towards any point lying outside
the measuring range and then, with the trigger in pressed condition, the desired range is to be scanned with zigzag movements till the
hottest point is located. Make sure that the measured object is not smaller than the measuring spot size for a given distance!

Most organic surfaces and materials have the emission factor of approximately 0.95. Metallic materials or glossy sur-
faces have a clearly lower emission value, for which you must be very careful while using the infrared thermometer 8895.
Metallic, glossy surfaces can be measured only with a compromised measuring accuracy. In order to achieve the maximum measuring

6 Maintenance and cleaning
6.1 Cleaning
For cleaning the infrared lens, simply blow out with your mouth to remove the dust particles. The remaining dust should be preferably
cleaned with a lens brush. The surface of the device can be cleaned with a slightly wet cloth. Please use only water and no chemicals or
detergents for this purpose.

6.2 Replacing batteries
The infrared thermometer 8895 requires two Alkaline 1.5 V batteries of type Mignon AA, IEC LR6 or equivalent for its operation. If the
voltage of the batteries under use falls below a certain minimum value, the symbol „Low battery“ [7] as an indication of empty battery
appears in the LC-Display. In such a case, please replace the batteries. For replacing the batteries, proceed as follows:
• Open the battery box, as shown in the picture below, by swinging out the battery box cover on the handle.
• Replace the batteries with two new ones of the same type and fold back the battery box cover on the handle.
Do not leave exhausted batteries in the device and remove the batteries, which have not been
used for long, because even leak proof batteries can cause corrosion. Chemicals, which can da-
mage the device or cause health hazards, can leak through the batteries.
6.3 Disposal of used batteries
The disposal of batteries together with house garbage is not allowed.
Batteries containing harmful materials are marked with the symbol as shown on left, which refer to the prohibition of dispoal with house
garbage. Used up batteries can be handed over at the collection points of your municipality or can be given to the company for disposal
during new purchase.
6.4 Scrapping and disposal
Electronic devices should not be disposed with the house garbage.
Old devices are disposed free of charge by our company as a gesture of ElektroG. Please send the device to our free service.
