It is generally expressed as the resistance (in Pa) of a metal plunger or probe when it is pressed into the soil. Soil firmness is the ability of the soil to resist compaction and breakage by external forces and is one of the aspects of soil properties. In addition, soil physical properties include soil texture, structure, porosity, etc. It involves the firmness, plasticity, permeability, drainage, water storage capacity, and ease of root penet-ration.\u003c\/p\u003e\n\u003cp\u003eSoil firmness consists of soil shear force, compression force and friction force. It is a synthetic indicator of the strength of the soil. When a metal plunger or probe is pressed into the soil, it is divided into two methods: dynamic load and static load, and the measured values differ from method to method, but there is a connection. The shape of the plunger has a cone, flat head, round ball and wedge, etc. These also have an effect on the measured value. The measured values for the same method are mainly determined by the soil texture, weight capacity and water content. Of these, water content has the greatest influence.\u003c\/p\u003e\n\u003cp\u003eSoil compaction predicts soil bearing capacity, tillage and resistance to root extension. Soil firmness is an important indicator of soil physical properties and is used to evaluate soil tillage. Firm soils can prevent water infiltration, reduce fertilizer utilization, affect plant root growth, and lead to crop yield reduction.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"celwidget aplus-module launchpad-brand-description-left aplus-standard\" data-csa-c-id=\"hsilnx-74ji87-szdvvi-4k4yf0\" data-cel-widget=\"aplus-launchpad-brand-description-left\"\u003e\n\u003cdiv class=\"a-section launchpad-module launchpad-module-brand-description-left\"\u003e\n\u003cdiv class=\"a-section launchpad-text-left-justify\"\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eSpecification:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRange:0~100kg\/cm²,0~1000N\/cm²,0~10000kPa\u003c\/p\u003e\n\u003cp\u003eProbe Length: 30cm; Connection Rod Length: 20cm; Total Measuring Depth: 50cm\u003c\/p\u003e\n\u003cp\u003eAccuracy: +\/-0.2% full scale +\/-1 digit\u003c\/p\u003e\n\u003cp\u003eMeasuring device: Kgf(gf)\/lbf\/N can be selected\u003c\/p\u003e\n\u003cp\u003eDisplay: 5-digit LCD liquid crystal display - device - mode - overload LED liquid crystal display - comparison LED liquid crystal display (reversible)\u003c\/p\u003e\n\u003cp\u003eSampling speed: 1000 times\/second\u003c\/p\u003e\n\u003cp\u003eDisplay update: \u0026lt;10 times, \u0026gt;15 times\u003c\/p\u003e\n\u003cp\u003eOverload capacity: 120% of the full range (LCD, LED flashing and buzzer sounding)\u003c\/p\u003e\n\u003cp\u003eA\/D transducer: 16-bit signal\u003c\/p\u003e\n\u003cp\u003eMicroprocessor: 8-bit high-performance microprocessor\u003c\/p\u003e\n\u003cp\u003eBattery operating time: all charged can be used continuously for about 10 hours\u003c\/p\u003e\n\u003cp\u003eCharging time: about 8 hours\u003c\/p\u003e\n\u003cp\u003eUse temperature: 0～40℃\u003c\/p\u003e\n\u003cp\u003eThe use of humidity range: 20% ~ 80%RH relative humidity\u003c\/p\u003e\n\u003cp\u003ePower supply: internal NIMI rechargeable battery, AC adapter\u003c\/p\u003e\n\u003cp\u003eOutput: USB, RS232C, analog output\u003c\/p\u003e\n\u003cp\u003eOutput parameters: analog (-2 to +2V), comparison signal (-NG, OK, +NG), open collector MAX 30V 10mA, ultra-negative Ho alarm output (OVL), open collector MAX 30V 10mA\u003c\/p\u003e\n\u003cp\u003ePeak hold: pressure or tension\u003c\/p\u003e\n\u003cp\u003eCompare function: settable high\/low set point with code\u003c\/p\u003e\n\u003cp\u003eStorage function: 999 measured values\u003c\/p\u003e\n\u003cp\u003eDisplay flip-flop function: measured value and measurement units\u003c\/p\u003e\n\u003cp\u003eAlarm: overload and +NG (off \/ on selectable)\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"celwidget aplus-module launchpad-brand-description-left aplus-standard\" data-csa-c-id=\"9ref61-7xsndr-jc74kz-z4jtxs\" data-cel-widget=\"aplus-launchpad-brand-description-left\"\u003e\n\u003cdiv class=\"a-section launchpad-module launchpad-module-brand-description-left\"\u003e\n\u003cdiv class=\"a-section launchpad-text-left-justify\"\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan class=\"a-text-bold\"\u003eOther functions\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e(1) automatic zeroing (1 second - 60 seconds setting)\u003c\/p\u003e\n\u003cp\u003e(2) Damping mode (4 level settings)\u003c\/p\u003e\n\u003cp\u003e(3) key sound can be turned off or on to choose\u003c\/p\u003e\n\u003cp\u003eAutomatic power off function: 1 minute - 60 minutes can be selected\u003c\/p\u003e\n\u003cp\u003eExternal connection switch: display hold, clear zero, and peak\/tracking selection\u003c\/p\u003e\n\u003cp\u003eMeasurement calibration: can be calibrated by themselves to suit the environment changes\u003c\/p\u003e\n\u003cp\u003eGravitational acceleration: can be adjusted for gravitational acceleration\u003c\/p\u003e\n\u003cp\u003eDimensions and weight\u003c\/p\u003e\n\u003cp\u003eMain body: length 220.5×width 78×height 32.3mm, about 520g\u003c\/p\u003e\n\u003cp\u003eMainframe + back panel + handle: length 230.5×width 90×height 44.5mm, about 1150\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"VTSYIQI","offers":[{"title":"Default Title","offer_id":47561295266013,"sku":"JSD1-HENGMEI-LUCKY","price":567.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/1749\/1165\/files\/1_6e557e32-19d8-47ac-9386-32210ffa76d0.jpg?v=1773208733","url":"https:\/\/www.vtsyiqi.net\/products\/vtsyiqi-digital-soil-compaction-tester-soil-firmness-tester-meter-with-kgfgf-lbf-n-three-unit-range-0-100kg-cm-0-1000n-cm-0-10000kpa-probe-length-30cm-connection-rod-length-20cm-for-soil-penetration-resistance-test","provider":"VTSYIQI","version":"1.0","type":"link"}
