Which Soil Moisture Sensor-Meter to Choose?

Deciding how to measure humidity can be complicated, but the plug-and-play METER soil sensor simplifies the process. When choosing a METER soil moisture sensor, the first thing you need to know is that all METER soil sensors have the same level of analysis and low sensitivity to salt (< 10 dS / m large EC) , temperature gradients and geography. Out of thousands of peer-reviewed publications using METER soil sensors, no single soil water sensor or water sensor can emerge as a favorite. The choice of sensor should depend on your needs and application. Use these ideas to help you identify the best ground water sensor or water sensor for your search. Explore these links for a more in-depth look at definitions, terms, and topics. 

How to measure soil moisture - CHOOSE THE RIGHT MEASUREMENT 

Volumetric water content 

If you want to measure the rise and fall of the amount (or percentage) of water in the soil, you will need a water content sensor (wetland sensor). Soil is made up of water, air, minerals, organic matter and sometimes ice (Figure 1). Water is one of its constituents, and represents a percentage of the total. To measure the water content of soil directly, you can calculate the percentage and density of water (gravimetric water content) by comparing the amount of water, such as mass, to the total amount of any other material. However, because this process is laborious, many researchers use soil water sensors that rely on automatic volume measurement called volumetric water content (VWC). Choose the right soil moisture sensor.

Longevity is important 

It is important for researchers to know how long a test will last so that they can choose a soil water sensor that will meet their expectations. METER's 10HS Soil Moisture Sensor and EC-5 Soil Moisture Sensor feature high-performance technology that lasts approximately 3-5 years in field use (minimum and warm conditions). TEROS 11, TEROS 12, TEROS 10 and TEROS 54 sensors are designed to last twice as long as our standard sensors thanks to polyurethane (epoxy) filling. Laboratory tests show that these sensors last more than 10 years before water seeps into the circuit board. If the test environment is tropical, hot and generally humid, always choose a long-life sensor. 


Compare the METER water content sensor with other methods 

In this 20-minute webinar, Dr. Colin Campbell outlines the differences between methods of measuring soil water content. It explores the concept of scientific measurement and the pros and cons of each method. He also explained what technology can be used in different types of research and why modern sensing is more than just sensors. Learn: 

The monitoring system behind the gravimetric system, capacitance, time-domain reflectometry (TDR), time-domain transmission (TDT), frequency-domain reflectometry (FDR), resistive sensors, and others.

Laboratory Pulverizer

Laboratory Pulverize is a disc mill that grinds virtually all materials to create fine network samples within the enterprise. This is a self-contained factory with a turntable with vertical level planetary movement. This function gives additional life to the moving parts and creates a uniform finer sample. Grinding occurs between two slices, one of which is stationary and the other is fast and eccentric. The slices are made of heat treated metal. With the help of a comfortable handwheel, you can set up six final products. This can happen even if the machine is running. The self-locking device keeps the Scharnern grinding chamber in place and provides easy and quick access to remove and clean soil samples. Powdering has the ability to reduce the quartz test of about half a kilogram in about a minute to 100 mesh. The powdering is 3 H.P. delivery. Motor, starter, š… "vš girdle and assemble 440 volts, 3 phase A.C. 50 Hz. Discovered diameter: 175 mm. Maximum feed size: 6 mm Yield: 250...

Ball Mill: An Introduction, Functioning Principle, Benefits and Specifications

  When milling machines come to the mind of people, they will consider only those machines which are oriented vertically that consist of whirling cutters.   In traditional manufacturing related businesses, milling machines are commonly utilised in the shape shifting of the materials used in the workplace. The purpose of used ball Mills is to create superfine and minute-sized materials for the making of unique and innovative products. Many methods can be utilized to blend materials which are known as high-power milling.   Many parts and machines are utilized for pulverising purposes and that's the reason high-power ball mill comes to the picture.  Ball Mill: Overview   Ball mill which is also called pebble mill machine or tumbling machine, is an apparatus for milling purposes that encircles cylinder- consisting balls and is arranged on a frame made with a suitable metal that can be length-wisely rotated with ease. The huge ball can break down by time...
