Description:
 
Although the fish tank may look fine, changing or unsuitable water temperature can have a negative effect on both fish and plants. Having a good thermometer and tracking water temperature at various times and days, will help you identify and correct problems due to temperature changes.
Our aquarium thermometers are one kind of liquid crystal thermometer.Low cost,no batteries required and easy to install.It is a small item, but have a big place in your aquarium.
 
 
What is liquid crystal thermometer:I
 
t is made with a substance called cholesteric liquid crystals which looks like small rod-like structures under magnification.Liquid crystals possess the mechanical properties of a liquid,but have the optical properties of a single crystal.Temperature changes can affect the color of a liquid crystal,which make them useful for temperature measurement.
There are two stages in the liquid crystals:

1. the hot nematic stage is the closest to the liquid phase where the molecules are freely moving around and only partly ordered.
2. The cold smectic stage is closest to a solid phase where the molecules align themselves into tightly wound chiral matrixes.

Liquid crystal thermometers portray temperatures as colors and can be used to follow temperature changes caused by heat flow.They can be used to observe that heat flows by conduction,convection,and radiation.
 
 
Tips of aquarium thermometer?
 
 When using LCD thermometers, there are a few tips to follow. First, do not place them in a location where they will receive direct sunlight, or near a heating or cooling vent. It is not recommended that an aquarium be placed in such locations anyway. Secondly, do not place the thermometer below the gravel level, as the reading will not be as accurate. Lastly, the thermometer reads best when viewed straight on, so place it accordingly. If you have to contort your body just to be able to see the thermometer, it's not in an ideal location.
