In principle, this thermometer is very easy to use. Insert batteries, make, start measurement, aim between the eyes, and then off again. I look forward already that you can turn off the thermometer to save battery power, this is today no longer inevitably usual. Now, however, this method of measurement has a hook. The temperature display is very dependent on exactly where you measure and the distance from the skin. Even the smallest change in position and distance from the skin produces a different result, reproducible data are thus not truly. All you get is a general trend, if the temperature is OK or not. Temperature curves over the day or a longer period so you can therefore not create. The accuracy of the display is 1.5 ° C in the range +/-.
This thermometer is therefore no more than an indication of whether the temperature OK, increases or is too high. But that you get even with the temperature strips that you can stick to an aquarium so to see, in which temperature range the water is. But do I need no decimal, because they are in this case waste. One would have to speak the same can be limited to green / yellow / red without temperature control, more are the thermometer that is not forth except a certain trend in which direction the temperature developed and whether it is OK.
