Thermometer, armometer for water, for aquarium, from 0 to +50 ° C, 15 cm

Thermometer for measuring water temperature in the aquarium. The thermometers installed inside the aquarium are attached to the suction cup, which is already in the kit along with the thermometer. It is necessary to fix the suction cup with a thermometer on a clean flat surface, peeled from plaque, algae and other substances. The presence of substances will not allow the suction cup to fit tightly to the surface of the glass and therefore the thermometer will not be fixed reliably. Subsequently, he may fall off. The thermometer should be located in a place where there is a small current of water (for example, next to the sponge), but not close to the heater. If you place it in part, where there is a very small current of water or a stagnant part, you will get the temperature of this particular area of ​​water, which may have nothing to do with the total temperature of aquarium water. If you place the thermometer close to the heater, it will show the heater temperature or the temperature of the water heated by the heater. Given that there is a temperature difference between the upper and lower layers of water in the aquarium, place the thermometer in the middle layer of water.
