Soil Moisture Temperature Humidity EC PH NPK Sensor

7 in 1 Rapid Soil tester meter

Important Reminder

The measurement of NPK adopts the general rapid detection method. There may be certain error. Use with caution for planting reference.

The existing electronic measuring method cannot accurately measure NPK. The error is large because the sensor only shows the trend of NPK.


  1. Plug and play testing, Rapid measure soil temperature, humidity (Moisture), conductivity (EC), PH, Nitrogen (N), Phosphorus (P), Potassium (K).
  2. 4.3" LCD touch screen easy to operate, displays real-time value, curve, logs, can set calibration on screen.
  3. Inside 5000mA rechargeable lithium battery, can continuously operate for 48 hours, comes with AC110/220V to DC13.6V charger.
  4. Support 1900 logs, settable interval of logging, can export logs to SD card, comes with 1GB SD card.
  5. Connect sensor by pluggable waterproof connector.
  6. Sensor cable length is 2m, can extend.
  7. Portable or wall-mounted.
  8. Can set up system language: support English, Korean, Japanese, Thai, Russian, Arabic, French, German, Italian, Spanish, Portuguese.
  9.  It can also be customized in other system languages.

Reminder of measuring

  1. NPK is measured using general rapid detection methods, which have certain errors and should be used with caution for planting reference. Existing electronic measurement methods cannot accurately measure NPK, it only displays the trend of NPK, just for reference.
  2. Probes are inserted in the soil for more than 2 minutes to measure the accurate value (PH need 5 minutes)
