High-precision PH measurement - quickly detect soil pH, easily read, guide scientific fertilization, optimize nutrient utilization, reduce diseases, avoid soil degradation, and help crops achieve high yield and quality.
Soil temperature detection - real-time monitoring of temperature changes to ensure that crops are in the best growth environment (15℃~25℃), avoid high temperature transpiration dehydration or low temperature growth stagnation, and improve crop resistance.
Portable design, simple operation - small and light, one-button measurement, suitable for farmland, greenhouse, orchard, laboratory and other scenes, easy to detect anytime, anywhere.
Applicable scenes: field planting, greenhouse, orchard management, flower cultivation, laboratory analysis, home gardening, etc.
Precautions!
(1) The metal probe of the instrument should not be inserted into the measured object or soil for too long to avoid oxidation damage and damage to the probe surface. After measurement, the soil particles on the surface of the metal probe must be wiped clean with a scouring pad in time.
(2) Before storing the instrument, make sure that the metal probe is clean and dry. Do not store it with other metal instruments.
(3) Different medium measurements: When the instrument changes the measurement point, or switches from soil to other medium measurements, the result of the first measurement is the medium activation buffer value, and the (electrode activation process) is not counted as the measurement result. The data with reference values must be averaged from multiple measurements after the second measurement. (Try to measure under the same conditions, such as temperature, humidity, measurement location depth, and soil density, which are more valuable for reference)
(4) When inserting the instrument into the soil: Be sure to press down in a clockwise direction to insert the soil for measurement so that the soil and the metal probe are in close contact. Remember not to turn the instrument back and forth to insert it into the soil, otherwise, it is easy to loosen the metal probe, break the connecting wire, and damage it, resulting in failure to measure.
(5) The instrument is only used to measure moist soil. Too high or too low humidity will have a significant impact on the accuracy of pH measurement. It is recommended to measure soil moisture within the range of 50%-70%, and the pH value is more valuable for reference.
(6) Under normal circumstances, the instrument has been calibrated before delivery, and the user does not need to calibrate. If the measurement accuracy is inaccurate after using it for a period of time, the user can calibrate the instrument.
(7) Calibration steps → Polish the pH electrode with a scouring pad or fine sandpaper → Clean the surface of the pH electrode → Insert it into the 6.68 calibration solution and press the calibration key for 5 seconds to enter the calibration mode → The screen pixel "6.8" flashes to automatically calibrate. After about 30 seconds, the screen will not flash and the calibration is completed. (Keep the probe still when entering the calibration state. If the probe is shaken, the calibration cannot be completed.) After the calibration is completed, if you need to verify the accuracy, you need to verify it in the order of 6.86 9.18 4.0. Be careful to avoid inserting the electrode probe in a strong acid or alkali environment for a long time, which may cause early wear of the electrode.
