Product Introduction Product Overview: Our soil speed tester can accurately detect and display various components in the soil in real time, such as soil temperature and humidity, soil conductivity, soil pH and soil nitrogen, phosphorus and potassium; soil composition indicators play an important role in the growth of crops The use of the detector can accurately detect various components in the soil, improve the soil through the detected data, achieve the purpose of monitoring the supply of plant nutrients, and make the crops in the best living environment, thereby increasing the yield.The shape of the sensor adopts a hand-held design, which is convenient for users to carry. It adopts a single-needle probe design. The probe is made of austenitic 304 stainless steel, which has a series of characteristics such as good corrosion resistance and toughness. Application Environment: The soil speed tester is suitable for a variety of gardening places, to meet the soil testing work of various planting places, and to comprehensively care for all kinds of flowers and plants. For example: farmland production, soil research, greenhouse planting, orchard nursery, horticultural planting, tree planting, potted planting and other environments. Product features: Real-time monitoring of soil compositionDetection of various organic components in soilUsing battery power supply, LCD digital displayThe interface parameters and functions are clearly displayed Product advantages Highly sensitive probe, fast response, stable and reliable, accurate measurementPlug and play, convenient and fast measurement Temperature Resolution: 0.1℃ Temperature Measurement Range: -20℃-60℃ Temperature Accuracy: ±0.5℃ Conductivity measurement range: 0-10000us/cmReaction Time: <1sProduct Size: Length 160.5mm width 37.3mm needle length 48mm Large-screen LCD digital display, clear reading Small zero drift and good repeatability Power Supply: 23A 12V alkaline dry battery power supplyMoisture Measurement Range: 0-100%Moisture Accuracy: 0-53%（±3%）/53-100%（±5%）Moisture Resolution: 0.1% PH Measurement Range: 3-9 PHNPK Range: 0-1999mg/kg (mg/L)NPK Accuracy: ±2%F.S.NPK Resolution: 1mg/kg (mg/L) Test Principle and Method The soil detector adopts the advanced FDR measurement method. FDR is a new type of soil measurement technology that uses frequency domain reflected electromagnetic wave pulse counting to measure soil.Install the product at the place to be measured, insert the sensor alloy probe vertically into the soil, and start the measurement. Long press the "SET" button, the device can work normally.The probe should be in full contact with the soil and compacted to ensure the accuracy of the data.The soil speed tester only tests soil and soil, and is not suitable for dry flour, pebbles, organic wood chips, liquid particles, etc.When the speed tester is inserted into the soil, please keep it at a depth of more than 10 cm. Insert the device into the area to be measured, press and hold the button for 1 second to display OPEN and then turn it on.After turning on the screen, the screen starts to display the value. When there are multiple parameters, the values will be displayed alternately. When the alternate display is displayed, short press the button to measure only a single parameter, and short press again to cancel. The device will automatically shut down after working for 3 minutes. During the working period, press and hold the button for 1s to display OFF, and it will also shut down. It is recommended to measure at multiple points and take the average value during the test. Press and hold the button for 1 second to display OPEN, then turn on the power, the display “————” flashes, enter the test waiting, insert the soil test during the test, the measurement time is 25 seconds, the data measurement is completed, and the value is locked for easy recording; Then pull out the instrument after After sufficient cleaning (the part of the needle close to the housing must be clean, and there should be no dirt between the needle and the needle), long press the screen button (1s) to restore the "------" flashing, and the next measurement can be performed again. , take the average of multiple measurements. It will automatically shut down after working for 3 minutes. During the working period, press and hold the button for 3s to display OFF, and it can also be shut down. This product is powered by 23A 12V alkaline battery, the battery can be replaced by the customer. Gently turn the screen to open, straighten the screen and take it out, you can see the battery holder, take out the battery holder and replace the battery inside. After replacing the battery, put the battery holder back into the case vertically, then straighten the screen cable and insert it into the space in the middle, first rotate the screen counterclockwise 2 times, and then slowly turn the screen clockwise to cover to prevent the screen cable Wound broken in shell.
