Soil salinity meter

This entry is provided by TOP Cloud Farming Equipment Network

Soil salinity meter can also be called soil salinity speed tester. The instrument is developed and manufactured by Top Instrument, and the main model is TZS-EC-I. We know that the greater the salt content in the water, the more conductive the water is. Therefore, the degree of salinity in water can be estimated based on the conductivity. Therefore, the soil salinity analyzer is sometimes called a conductivity meter!

Introduction

    Soil salinity meter can also be called soil salinity speed tester. The instrument is developed and manufactured by Top Instrument, and the main model is TZS-EC-I. We know that the greater the salt content in the water, the more conductive the water is. Therefore, the degree of salinity in water can be estimated based on the conductivity. Therefore, the soil salinity analyzer is sometimes called a conductivity meter!

principle

    The soil salt can be directly extracted with water. After the extraction, it is quantified and put into an aluminum box for drying at 90 degrees. When there is no moisture, it is completely dried at 105 degrees. An analytical balance is used to measure the quality of the aluminum box to determine the soil salt content.

Function parameter

    Soil salinity meter

    1. Small and beautiful, easy to carry, touch button, large screen dot matrix LCD display, full Chinese menu operation. [1]
    2. One-click switching, which can be manually recorded or set the sampling interval at any time without the computer to automatically record and store data.
    3. Manual mode: The working mode is to save once and press once. It can record the time and various environmental parameters pressed at that time, and can switch between automatic mode and manual mode at any time. It can be stopped at any time and data can be connected to the computer. , The software will automatically generate curve graphics, which can be printed.
    4. Automatic mode: first set the interval time, the instrument can automatically record data according to the set interval time. The data can be connected to a computer, and the software will automatically generate curve graphics that can be printed.
    5. Can be connected to a computer for data upload, processing and backup.
    6, AC and DC dual-use, you can get the field to collect data anytime, anywhere, you can also place the recording location for a long time to collect.
    7. Powerful data saving function, can store up to 120,000 pieces of data.
    8. Data that has been saved in the host after power failure is not lost
    9. The computer software has powerful data processing functions (statistics, analysis, display, query), which can form a graph of the collected data for visual display. The collected data can also be stored as an Excel spreadsheet file, which is convenient for users to save and process the data, or draw bar charts, pie charts, prints, etc. The software is permanently upgraded for free
    10. The probes are consistent, and the probe sockets of different parameters are interchangeable without affecting accuracy.
    11, the instrument has a 32-channel synchronous detection capacity, can be within the capacity range, the number of probes is unlimited.
    12. The parameters can be combined as required, and the sampling interval of each sensor can be set independently.

    Functional parameters of soil salinity meter:

    1. Large-screen Chinese LCD display, the sensor can be directly buried in the soil
    2. Measurement range: 0.00 ~ 19.99ms / cm
    3. Temperature range: -5 to 50 ° C; working environment temperature: -5 to 50 ° C
    4. Measurement accuracy: EC ± 2℅ full scale; temperature ± 0.5 ℃
    5. Resolution: 0.01ms / cm
    6. Temperature compensation: 0 ~ 50 ℃
    7. Power supply: 5 AA batteries, power adapter

Instructions

    step:

    1. Arrange the aluminum box, completely clean, dry, number, and weigh it as M0 in the analytical balance.

    2. Weigh a certain amount of soil samples (forget the numbers!), Extract the salt in the soil with a water-soil ratio of 5: 1 (?), And suck a certain amount of (?) Extracts into the numbered aluminum box Weight, put in a 95 degree oven to dry without moisture, adjust 105 degrees, dry, store in a drying vessel, and quickly weigh the dried aluminum box mass M1 with an analytical balance.

    3. Calculation: M = M1-M0, salt content = | (M1-M0) * (sample absorption / water addition) / quality of soil sample.
