Involvement:General (knows how to use it) - Ownership:1 day to 1 week
Looks good as it seen on the picture and feels good in hand. Some foreing smell of plastic but not very strong.
Construction was good, looks like pro-instrument. But there is no instruction and therefore there is no accuracy of measuring and working condition, i.e. can it be used out of door and what is the working temperature and moisture.
Accuracy was tested against calibrated contact termometer and was found within 1-2 degrees Centigrade. Quiet enough for me. Meantime, there is a symbol in the display E = 0.95 but without explanation or any changes in the figure while measuring.
It would be batter if there were automatic indication when mausuring of temperature completed. At the moment it's not clear how long it's necessary to measure temperature - is it enough 1 sec. ot it's necessary to measure for 3 or 5 seconds.
Overall rating was stated as Satisfactory (3) due to absence of the instruction (small piece in English with technical characteristics and some brief explanations would be enough), no accuracy of the measurements and no working temperature range were stated. Absence of mentioned above put usfulness under question.
