High Precision NPK Soil Tester Meter Nitrogen, Phosphorus And Potassium Soil Detector For Greenhouse Garde Farm

NOTE:

YG-LY607 is Nitrogen tester

YG-LY608 is Phosphorus tester

YG-LY609 is Potassium tester

Use steps:
1. Press the on key to start the machine;
2(1). Precision test method: First, put the soil (it is recommended that the soil be dried) and pure water or distilled water (it is recommended that the Wahaha pure water) into a container according to the ratio of water 2: soil 1 to make a uniform paste state. Then the metal probe of the instrument is vertically inserted into the soil of the container at a depth of 6-8cm, the response time is about 10 seconds, and the number displayed by the instrument is the actual measurement value. (This test method unified the soil moisture and removed the influence of humidity factor on the test result, which was close to the original value of the soil)
2(2). Quick measurement method: First, the soil measuring point to be detected is poured with pure water (or distilled water) to a depth of at least 10CM or more (the best humidity is 70-80%), and then the instrument metal probe is inserted vertically clockwise into the wet soil at a depth of about 8cm, so that the soil and the probe metal surface are easily and evenly contacted, the response time is about 10 seconds. The number displayed by the instrument is the actual measurement value. The tightness of the soil will directly affect the result of the measurement value, so it is required that the multi-point measurement of the above method must be carried out at the position of different measurement points to order the average value.
(The value of this test is closer to the value of the soil in its current state, taking into account environmental factors that can affect the measured value)
3. After each measurement, the surface of the metal probe should be cleaned with a paper towel or cleaning cloth in time until the instrument returns to a zero value state.
4. Calibration method: under normal circumstances, the instrument has been calibrated before leaving the factory, and the user does not need to recalibrate. Instrument precautions
1. The instrument metal probe inserted in the soil or paste soil (other media to be measured) should not be too long, so as to avoid oxidation and water seepage, thereby damaging the metal surface and internal structure of the probe, resulting in inaccurate or unstable measurement data of the instrument. After each use of the instrument, the residue on the surface of the metal probe must be thoroughly removed with a paper towel or cleaning cloth in time, and the water on the surface of the metal probe must be dried with a paper towel.
2. After use, press the switch key to shut down, clean the electrode and save it after reducing pollution.
3. When the instrument is not in use, do not rub the surface of the metal probe directly with your hand, and keep it clean and dry, away from magnetic objects and other gold objects.
4. During use, insert the electrode into the soil as far as possible to avoid collision with hard objects.
5. After the low power alarm, replace the battery in time to ensure the normal use of the product.
