一. The role of water temperature and salinity in one
The thermometer is intuitive, simple and easy to use
Whether ornamental fish can grow healthily depends on the water quality, the environment, the bait, the method and the mentality. The thermometer to be talked about today is an important item in environmental factors.
It is the best tool for measuring ambient temperature. At present, there are many methods for measuring temperature, such as hand-held induction thermometers, temperature guns, sensor temperature measurement and so on.
But I think it is still reliable to use the simplest thermometer. Not for anything else, just because other means are too wrong. Thermometers are the simplest, most intuitive, and have no errors. Unless your thermometer is a substandard product.
2. There must be a thermometer in the fish tank
Temperature is one of the important indicators of the water environment, it directly determines whether fish and other aquatic organisms can survive, and its drastic changes may lead to
the occurrence of fish diseases. Therefore, the temperature must be monitored in real time, especially during the period when the temperature difference between morning and evening is large and the seasons change. And who will reflect the change in temperature? The answer is a thermometer. Therefore, the fish tank must have a thermometer.
Three buy a thermometer
There are many types of thermometers on the market, and the quality is also uneven. Therefore, when purchasing, you must go to a large fish store, where the quality of the products is still guaranteed, reducing the possibility of being deceived.
When choosing, ask the boss for a few more, and the closer the displayed temperature is to the actual temperature, the better. What if you don't know the actual temperature? The answer is also very simple, just pick the one that is closest to the average temperature.
When choosing, choose the one with a clear scale line, and the scale line is located in the front of the reading position, which is convenient for reading in the future.
二. Correct use of water temperature and salinity two-in-one thermometer
1 Placement
Keep thermometers away from lamps and heating rods. Lamps and heating rods are devices that continuously generate heat, and their heat will affect the reading of the thermometer and affect our judgment on the change of water temperature.
The thermometer should be placed in the tank where the fish is, not the pump or filter compartment. Most of the aquariums we bought have a temperature display function, but it shows the temperature of the bottom filter compartment, not the real water temperature.
Because its temperature sensor is installed in the cabin of the bottom filter. Although the water temperature of the bottom filter tank and the water temperature of the water tank where the fish are located are not very different, it does not mean that there is no difference. The bottom filter tank is surrounded by a sealed structure, and its water tank needs a lot of heat preservation compared to the water tank above.
I bought the thermometer to serve the fish, so be sure to put the thermometer in the tank where the fish is.
2 Diligent reading, fish will do
I always envy other people's fish for giving birth again. I envy other people's fish in good condition and color. I never look for the reason in myself.
After buying a thermometer, just stick it on it, never look at the temperature, never read it, there are many aquarists like this. As everyone knows, doing this is the same as not having a thermometer. Since you have already bought it, why not use it?
Observe the changes of the thermometer and adjust our water temperature at any time, adjust our water changing frequency and feeding frequency, which can help ornamental fish grow, color, reproduce, and prevent the occurrence of diseases.
3 The heating rod is only reliable when used with a thermometer.
Some aquarists have purchased a professional fish tank heating rod, and they don't care if they are turned on. The temperature control of the heating rod can be said to be quite poor. There are a lot of heating rod settings that are ten degrees different from the actual value, you know?
Many aquarists have such a real experience. The set temperature is 25 to 28, but the actual temperature is 35 degrees. The heating rod is still working, and I have never seen it stop. If this goes on, will the fish be safe? Is the fish still good?
Therefore, the heating rod must be used with a thermometer.
4 Handle with care
The outside of the thermometer is a glass structure, and the inside is mostly colored kerosene liquid. When we usually need to move the thermometer, we must handle it with care to prevent bumping and prevent the internal kerosene from flowing out and polluting our water quality.
5 The best with a protective cover
When placing the thermometer, pay attention to stick the thermometer in the water inside the front glass, and the thermometer should be completely submerged in the water. If there is a crash box, attach the crash box to prevent large fish from crashing the thermometer.

三. The working principle of the water temperature and salinity two-in-one
The conductivity of the aqueous solution increases with the increase of the salt content, that is, the greater the salt content, the lower the resistance and the better the conductivity. When light enters another medium from one medium, refraction occurs, and the ratio of the sine of the incident angle is constant. This ratio is called the refractive index. Using the property that the content of soluble substances in the salt solution is proportional to the refractive index in ordinary environments, the refractive index of the salt solution can be measured, so that the concentration of the salt can be calculated.
Because the refraction phenomenon occurs when light enters another medium from one medium, and the ratio of the sine of the incident angle is constant, this ratio is called the refractive index. Using the content of soluble substances in the salt solution and the refractive index are proportional to the normal environment, the refractive index of the salt solution can be measured, so that the salinity meter/refractometer can calculate the concentration of the salt. Note: Salinity meter is a subdivision type of refractometer (refractometer)
四. How to clean up broken mercury
Mercury can generally be collected with paper towels, beverage bottles, etc. Mercury is a liquid metal that is volatile and toxic. If the mercury thermometer is damaged, the windows should be opened in time for ventilation. Immediately collect scattered mercury without touching it with your hands. You can use a paper towel or other item to store the mercury in a beverage or mineral water bottle. Don't pour it down the drain, and don't pour the mercury on the ground and wait for it to evaporate, because mercury is very toxic.
五. Life application of salinity two-in-one thermometer
Due to the simple operation, the user can quickly read the salt concentration or the specific gravity of seawater. It can be applied to the concentration management of seawater or artificial seawater used in seawater aquariums used in oceans, fish farms, and seawater aquariums, and saltwater used in fish storage.
六.Precautions for the combination of water temperature and salinity
1. Avoid measuring strong alkali and strong acid liquid solution, and avoid the solution causing damage to the glass probe.
After the measurement, please clean the probe and cover the probe cover. If the instrument has not been used for a long time or the probe has been replaced, the instrument should be calibrated before measurement to avoid affecting the measurement results.
2. Please operate the instrument correctly and use it in the environment limited by the technical parameter table.
3. Avoid exposure to sunlight.
4. Avoid using solutions with unknown salinity values for calibration.
5. Avoid contact with corrosive chemicals.
6. If the instrument has not been used for a long time or the probe has been replaced, the instrument should be calibrated before measurement to avoid affecting the measurement results.
