Thermometer for water, for aquarium, set 2 pcs

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 let the suction cup tightly fit to the surface of the glass and the thermometer will be fixed unreliable. 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 stagnant part, you will get the temperature of exactly the water area that may have nothing to do with the average 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. Considering 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.

the liquid crystal thermometer is designed to measure water temperature in the aquarium. The thermometer is attached to the aquarium wall strictly in an upright position for the correct temperature display, on a flat clean surface from the outer side of the aquarium.

Temperature readings are displayed on the scale with rectangles of three colors (brown, green, blue). The current temperature is located in a green rectangle, and if there is no green color on the thermometer, then the current temperature is calculated as the average arithmetic between the values ​​on the blue and brown rectangle.
