Do you really know the aquarium thermometer?

Let's learn the knowledge of the aquarium thermometer and fully understand this humble fish tank device.
The first misunderstanding: Misunderstanding that all aquarium thermometers will not be bad
Few friends have ever seen a malfunction of a water temperature meter, so there is a misunderstanding that the water temperature meter will never be bad. To resolve this misunderstanding, we need to first figure out what the aquarium thermometer is.

A water thermometer is a kind of thermometer, more precisely--a water thermometer is one type of thermometer. Whether it is a gas thermometer, a liquid thermometer, or a solid thermometer, it is essentially the application of the principle of thermal expansion and contraction.

Thermometers are divided into digital thermometers and pointer thermometers. Both of these thermometers use corresponding products in our aquarium, but the most we have seen are digital thermometers. From the main material, most of them are glass or plastic products.

Obviously, these two materials are not very "strong", and it is not surprising that a little situation happens occasionally. On the other hand, any commercial product has a reasonable residual rate, which is understandable.

Conclusion: Most water thermometers are cheap and have a certain failure rate. Although this failure rate is small, it also exists objectively.

The second misunderstanding: Misunderstanding that the data of all the aquarium thermometer is accurate
The accuracy of the results displayed by different water thermometers is different. Even the same product of the same brand may have data deviation. There are five types of water temperature in the aquarium market. The first type: pointer type anti-collision water thermometer. This type of water thermometer is used more by friends who play turtles. It is rarely used by aquarium fish players, but it can be used if desired. It is relatively sturdy. The characteristic is that it looks like a dashboard with a pointer.

The second type: liquid crystal digital display water thermometer. It is also divided into two sections. One is with a probe and is more accurate; the other is without a probe and is very inaccurate.

The third type: glass water thermometer. At present, there are many people who use glass water thermometers, especially the small fish tanks, which are generally used in this type. Glass water thermometers include diving with suction cups, hanging with hooks, and floating with floats. They look classic and have high accuracy, and they are also the category with the lowest failure rate.

The fourth type: WIFI water thermometer. It is estimated that many friends have never used it, which belongs to the latest fish tank temperature gauge. This is a thermometer that can display the water temperature of the fish tank through WIFI. It has been designed with the heating rod to achieve the purpose of remote control of the water temperature of the fish tank.

The fifth type: sticker-type water thermometer. It's like a piece of black paper sticking to the outer wall of the fish tank, there are not too many people use it.

Conclusion: The most accurate data is the cheapest glass water thermometer, the most inaccurate is the external tips liquid crystal digital thermometer.
