At present, we know about the measurement of soil properties indicators: soil moisture, soil temperature, soil nutrients, soil heavy metals, soil salinity, soil pH, soil water potential and other parameters. For soil moisture, there is a soil moisture measuring instrument; soil temperature, a soil temperature measuring instrument; soil nutrients, a soil nutrient fastness meter, and the like. An indicator that there will definitely be an instrument that can perform measurements. However, with the development of science and technology today, the function of the instrument is no longer single, and we can integrate several indicators on one instrument for measurement. For example, a soil moisture temperature measuring instrument is capable of measuring soil moisture and soil temperature. A soil temperature measuring instrument is an instrument for measuring soil temperature. Soil temperature influences the growth and development of crops, and understanding the soil temperature has great help in improving the growth efficiency of crops and increasing the utilization of fertilizers. The soil temperature is closely related to the activity of microorganisms in the soil, and the temperature affects various chemical processes of the microorganisms. The soil temperature is also crucial for plants. The plant grows in the soil and it must be provided by the soil to provide the ambient temperature for its growth and development. It can be said that within a certain range, the higher the temperature, the faster the plants grow; the lower the temperature, the slower the plants grow. This is well understood because of the high temperature, the accelerated metabolism of the plant, and the rapid growth. On the contrary, it is slow. Therefore, the measurement of soil temperature is an indispensable step when assessing the yield of plants or understanding other plant traits. At present, there are many types of instruments that can measure soil temperature, which are mainly divided into four categories: soil thermometers, soil moisture temperature meters, soil moisture salts temperature meters, and soil moisture conductivity meters. All of them have in common that they are able to measure soil temperature. The soil thermometer is a simple instrument that measures the single parameter, soil temperature. Here we compare and analyze the differences in the characteristics of these major soil temperature measuring instruments: Table Comparison of several soil temperature gauges category index Soil thermometer (11000 type) Soil moisture temperature measuring instrument (TZS-IIW type) Soil moisture salt temperature measuring instrument hydra Soil moisture conductance temperature measuring instrument WET temperature range -40-150°C -10-60°C -10-65°C -5-50°C Accuracy ±0.5°C ±0.5°C ±0.6°C ±1.0°C testing time 2s ≤2s 5s 5s Reading group Timely reading 2000 3000 2100 cable length No 100m 30m In the above table, only a few parameters have been compared. If there are inappropriate places, I hope to point out. Then, from the above table, we can conclude that a simple soil thermometer can measure the maximum temperature range, but under normal circumstances, the soil temperature will not be lower than -10 °C or higher than 60 °C, so the measurement range is too large It is not necessary either. The soil thermometer measures a wide range of temperatures and is low in price, and is suitable for relatively coarse temperature measurement of the soil. However, with the development of agriculture and the development of computer technology, more and more people have begun to select soil temperature measuring instruments because it is convenient and simple. It can display different parameters on the panel, has memory function, and can record thousands of records at one time. Data. Of course, the relative price will be much higher than a simple thermometer. The products of soil temperature measuring instruments are now many and continue to be improved. Gps, mp3, mp4 and other functions have been synthesized into various soil temperature measuring instruments in succession, making the temperature measuring instrument more intelligent and high-end. Moreover, in terms of prices, there is also a certain degree of competitiveness. Different functional products correspond to different consumers. As long as you look for what you need for your product, you can buy the right product. Below, attach the soil thermometer (Model 11000) and Soil Temperature Meter (Model TZS-IIW) that were previously compared.

Bicycle Headset is a small but important part of bicycle direction system. It is a bearing assemble at head tube that connects the handlebar to the top tube of the fork, allowing it to be rotated for steering and balance purposes. Because of the protruding shape of the bearing base, so it also called a Bicycle Bowl Set.
Our Bicycle Head Set made of aluminum alloy so it has a good strength and nice regular shape, the surface is glossy and has bright color due to the good baking paint. Some shop also sells the steel Bike Headset to use on lower-end public bicycles or very cheap bikes, but will rust if gets wet or keep in humid environment.
