5-in-1 Soil Tube Sensor

Measures: Temperature + Moisture + NPK (Nitrogen, Phosphorus, Potassium) + EC (Electrical Conductivity)

Measurement Ranges:

• Soil Temperature: -15°C to +80°C
• Soil Moisture: 15–100% (non-condensing)
• Soil EC: 0–1999 µS/cm
• Soil NPK: 0–1999 mg/kg

Accuracy:

• Temperature: ±0.5°C
• Moisture: ±5%
• EC: ±3% F.S.

The sensor installation steps

Step 1

Use a soil auger to drill a vertical hole at the selected location (90° angle).
Ensure the hole allows smooth insertion and removal of the sensor.

Step 2

Slowly rotate the sensor in one direction while pressing it down into the hole.
(Do not pull the sensor upward during the insertion process.)

Step 3

Backfill the hole with soil.
Ensure the sensor is installed at a depth level with the surface of the hole opening.

Step 4

After installation, connect the power supply — the sensor is ready for normal operation.
