This purchased for 30 device I have now done several tests and am very happy for my purposes.
For the use of measurements in the apartment (water temperatures, cooling / freezing), on car, motorcycle (tire temperature after riding), cold spots on windows / doors, radiators, pipes, etc., the device is ideally suited.
The most important points for me I want to briefly list with small comments.
Positives:
---------
+ Size and shape
Only approximately 17 x 4 x 2,7 cm.
No "pistol grip", thus easily transportable in any jacket pocket
Ideal to take with you in case of need at any time of year to
+ Weight
According to my scale 123 grams
+ Two standard AAA batteries (included incl.)
This battery type is available everywhere, not too expensive.
In addition, I will also be able to operate the device with batteries.
For the 9-volt battery (mostly for devices with "Pistol Grip") you need some expensive battery chargers, other smaller gauges turn button cell batteries are not rechargeable and also in the long run too expensive
Protected + laser unit against dust
Before the laser a plastic cap is attached.
For the measurement of this is taken and "blind" attached at the rear end.
The cap can not be lost by embarrassed.
After the measurements, simply push forward again.
(Manually set) + Built-in time in 12h or 24h format
This requires Whether one is sometimes an open question.
Of course you can take a picture of the display with the measurement object.
Thus, the receiver or the hard copy has always measured time with temperature with this
+ Stopwatch
A practical application of this device I have not found.
But that is now times with in it
+ MIN / MAX / duration measurement
Depending on the setting of the minimum / maximum value in the display stops
or it is constantly being updated without the need to hold the scan button
+ Emissivity setting
I can not find a device with 100 (!), In which the emissivity value is "infinitely" adjusted.
The setting can be adjusted in 0.01 increments from 0.05 to 1.00.
Nearly all devices in this price range have an unchangeable fixed value of 0.95.
This is info away a disadvantage as is required for light heating bodies 0.80,
with steel even just 0.24, etc
In extreme cases, this leads to the bad Rezesionsbewertungen the other devices because the "wrong message" quite well at temperatures below 50 degrees can be between 5 and 30 degrees, which is not insignificant.
Clear you have to deal with it, but over time you get the out and can thus be its earnings view still "accurate".
In the manual some sample values are listed. This can for example take a picture with your phone and run with them, so as not to have to know all the values by heart.
+ Manual in German
It is a small very well-described manual in German / English here.
While everything is relatively well described on about 8 pages per
+ Wide operating temperature range
According to the manual measurements in Umbegungstemperaturbereich from 0 to 50 degrees are possible.
Many other devices only permit between 10 and 40 degrees.
At 45 degrees you will rarely need measurements.
However, between 0 and 10 degrees often when / autumn / winter in the garden, garage or outside on the engine of the car something wants to measure, for example in the cellar or even in spring. For me a clear advantage.
+ Fast adaptation for measurements
One should not fast on the road measure of the warm apartment which and back course. The measurement will almost always be extremely different, as the unit should have the ambient temperature.
Within 5 to 10 minutes adjustment time but already you get good results.
Other devices need this moon minutely 15 to 30 minutes.
+ Central measuring point display for lowest measurement deviations
In order to determine the distance to the object to be measured accurately, the device sends two red laser points. You have to be as close to the point to be measured, to overlap the two points and only one can be seen.
Negatives:
----------
- Low measuring distance
You have to be off about 1.8 cm at the measuring point.
Other devices allow accurate measurements at 2.5 to 3 cm distance.
The farther you remove the device from the measured object, the greater the deviation
Note: Bigger is is my test measurements, eg instead of 20 degrees, deviations up to 15%. As an approach (something cold or hot?) Enough, but if it more accurately (the point is the same temperature as another?) Must be, of course not.
- Lower temperature range than most competitive products
Measurements can be carried out on rear panel only objects with temperatures from -55 to +220 degrees as specified.
Most other devices create +300 to +400 degree, but how exactly then is the measurement result, everyone should check for themselves and what should be measured and how often one needs accurate values between 200 and 400 degrees?
This device is more than 220 degrees, only a "Hi" for high on.
On a cigarette I could then see this by measuring at the glowing spot on the screen.
- Backlight
That would be the only thing I'd really like to see more!
Unfortunately, the display is unlit. This one still needs at evening outdoor measurements a light source or must be able to read to a brighter source to the measurement and kept coming back to the point to be measured.
Conclusion:
-------
The device is called according to instruction while - Infrared Thermometer "professional" - but if this is suitable for "professionals", I can not judge.
For the private / home / amateur use it is at this price is definitely adequate.
If someone needs a device that performs to the degree, measurements, I would advise against it.
But if anyone needed a device that is relatively small and comfortable carry, the laser unit should be protected, the price offers low and a relatively good balance of everything, then I would highly recommend this device, in my experience!
