PH-TRSQ Soil Moisture Monitoring Station is an automatic soil moisture monitoring system that integrates soil temperature and humidity collection, storage, transmission and management. The whole machine is composed of multi-channel data acquisition instrument, soil moisture sensor (soil temperature sensor), computer software, etc.

Mainly record soil salinity, soil temperature, soil moisture, humidity environment, air temperature and humidity, atmospheric environment, it is best to turn on the regular recording function, soil moisture speed meter data real-time tracking, GPS function, at any time to do analysis The best use is the TZS-5X multi-parameter moisture recorder of Zhejiang Top Instrument, remember to analyze more quickly.

It is necessary to use a portable soil moisture tester to monitor soil moisture quickly and accurately. During the critical period of monitoring by the portable soil moisture tester, it is necessary to pay attention to timely replenishment of moisture according to the changes in soil moisture. The temperature is higher during this period, the evaporation of the water surface is the highest value of the year, although the precipitation has also increased, but the actual results from the monitoring of the portable soil moisture tester show that the water consumption is greater than the precipitation, so the portable soil moisture tester should be used to strengthen the monitoring of soil moisture, timely replenish the evaporated soil moisture, and ensure the water demand of crops.

Portable soil moisture testers to carry out soil moisture monitoring are essential for the development of modern agriculture.

Soil moisture meter can be detected.

Soil moisture measurement range (six layers): 0 100% Accuracy: 3% Resolution:

Soil temperature measurement range (six layers): -40 120 Accuracy: Resolution:

Rainfall measurement range (three sets): Accuracy: 3% Resolution:

There are two ways to express the amount of water in the soil: one is expressed by soil water content, and the water content by weight and volume, and the relationship between the two is converted by soil bulk density. The other is expressed in terms of soil water potential, and the negative value of soil water potential is soil water suction.

FDR (FrequencyDomain Reflectometry) is to measure the apparent permittivity of soil ( ) according to the propagation frequency of electromagnetic waves in the medium by using the principle of electromagnetic pulse to obtain the soil volume water content (V). The measurement principle, system installation, measurement method and application of FDR system in continuous dynamic monitoring of soil moisture are introduced, and the actual measurement results are corrected, which can be used as a reference for FDR correction. The application practice in the Huangfuchuan River Basin in the semi-arid area shows that FDR has the advantages of simplicity, safety, fast and accurate, fixed-point continuous, automation, wide range and less calibration, and is a recommended soil moisture measurement instrument.

TDR (TimeDomain Reflector) is a common principle for rapid detection of soil moisture, which is based on the principle that the waveform is reflected on a mismatched transmission line. The waveform at any point on the transmission line is a superposition of the original waveform and the reflected waveform. The TDR principle has a response time of about 10-20 seconds, making it suitable for mobile measurement and fixed-point monitoring.

The measurement results are not affected by salinity, and the disadvantage of TDR is that the circuit is more complex and the equipment is more expensive. FDR has almost all the advantages of TDR compared to TDR testing principle, and the probe shape is very flexible. The more exaggerated ones can even be measured in the movement of a tractor made into a plough shape.

FDR requires less correction work than TDR. For many years, it has been difficult to break through the accuracy of the FDR principle of soil moisture meter, which has become a stagnation in the development of FDR soil moisture meter. After years of research, this difficulty has finally been broken.

A soil moisture meter based on FDR principle was developed, with an accuracy of 3%.

The mobile soil moisture monitor emits a signal of a certain frequency, the signal source probe transmits, reaches the soil end, and part of the signal is reflected back to the transmission line due to the impedance mismatch, so as to form a standing wave superposition with the original signal, because the reflectivity depends on the dielectric constant of the soil, and the dielectric constant of the soil has a certain linear relationship with the water content of the soil, so that the standing wave superposition signal can be detected to obtain the soil water content. The mobile soil moisture monitor independently developed and produced by Top Yunnong is also known as soil moisture meter and mobile soil moisture tester. The mobile soil moisture monitor has a GPS positioning function.

It can display the accurate information (longitude, latitude) of the sampling point at any time, and the location information of the sampling point can be displayed at any time. Top Yunnong's mobile soil moisture monitor is a handheld soil moisture meter, which can mainly detect soil moisture, and the soil testing instrument related to this is the TZS series, such as TZS-1K can measure soil moisture, TZS-2X can measure soil moisture, soil temperature, TZS-3X can measure soil temperature, soil moisture, atmospheric temperature, etc., you can buy according to your actual needs, It is hoped that the mobile soil moisture monitor can help growers in Northeast China to survive the spring drought period smoothly and have a bumper harvest! <>
