TDSPortable Salt Meter (TDS Salt Meter)/soil conductivityinstrument(EC calculation)

model:TDS

1、 Instrument Introduction

Soil electricityConductivity (salinity) meter is used to test soil water solution (soil water ratio)=1：1~5：1）The salt contentTDSThe value and conductivity of the solution are used to determine the high or low salt content of the soil. At the same time, it also has the function of testing environmental temperature. The product is widely used in industries such as agriculture, forestry, and water treatment.

Soil salinity analyzer is used to test the salt content of soilppmValue is used to determine the salt content of the soil (displayed concentration multiplied by dilution factor).

Can be directly inserted into soil testingIt can also measure the salt content (ppm) and EC of soil water solution（μs/cm）Value.

IITesting items:

soil solutionTDSpriceppm（mg/L）, conductivity μs/mCelsius temperature ℃, Fahrenheit temperature ℉.

3、 Basic functions:

（1）Switch button（ON/OFF）Function:

Power on: Press this button while the device is turned off to turn it on.

Automatic shutdown: after use60sIf there is no operation, it will automatically shut down.

Manual shutdown: Press and hold continuouslyON/OFFButton 2sShut down.

（2）Function selection button (Shift)）By default, the total salt content of the solution is displayed upon startupppm（mg/L）Press this button once to display the conductivity of the test solutions/cmValue, press again to display Celsius temperature ℃, press again to display Fahrenheit temperature ℉; Repeat the cycle to display the above content.

（3）Clear the lock reading and retest.

（4）Automatic testing and locking of readings:Insert directly into the soilMiddle orInsert it into the soil water solution to automatically read and display the correspondingTDSValue or conductivity μs/mValue. Then it automatically locks. The corresponding unit symbol flashes when the reading is locked.

（5）Scale function: Scale according to national standards. And appropriately refer to international usage conventions.

（6）Backlight function: It adopts low-power backlight, which is convenient for testing at night and in low light places.

（7）Manual adjustment: It has a manual adjustment function, which is easy to adjust during factory and calibration.

（8）Large screen display: adopting high distortionSTNThin fully transparent LCD screen displays four digit numerical values and corresponding physical units.

（9）Supply voltage:CR2032Battery,DC3V；210mAh.
