1. Product Introduction
1.1 Product summary
It is suitable for measuring soil temperature and water content. It is calibrated by
comparison with Germany original high precision sensor and soil drying drying weighing method.
It has high precision, quick response and stable output. By the soil salt content of small, suitable
for all kinds of soil. Long-term buried in the soil, resistant to long-term electrolysis, corrosion
resistance, vacuum potting, completely waterproof.
1.2 Scope of application
Widely used in scientific experiments, water-saving irrigation, greenhouses, flowers and
vegetables, grassland ranch, soil speed measurement, plant culture, sewage treatment, grain
storage and a variety of particulate matter moisture and temperature measurement.

2. How to use
2.1 speed measurement method:
Select the appropriate measurement location, to avoid the stones, to ensure that the needle
does not touch a hard object, according to the required depth of measurement to put aside the
topsoil, to maintain the original soil below the tightness of the sensor vertically insert the soil,
insert Can not be left and right shaking, a small measuring point within the recommended average
of several measurements.
2.2 Buried measurement method:
Vertical digging diameter> 20cm pits, the depth of the probe will be the level of the probe
inserted into the pit wall, the pit filled with strict, stable for some time, you can for several days,
months and even longer measurement and recording.
2.3 Note:
1, the measurement must be fully inserted into the soil needle.
2, to avoid direct sunlight to the strong sunlight caused by the sensor temperature is too high.
Note the use of wild lightning.
3, do not violent bending steel needle, do not pull the sensor pull lead wire, do not beat or
violent impact sensor.
4, the sensor protection class IP68, the sensor can be soaked in water.
