Deskripsi
RK520-01 Sensor Kelembaban & Suhu Tanah untuk mengintegrasikan pengukuran kelembaban dan suhu. Probe stainless steel dimasukkan ke permukaan tanah atau profil tanah untuk menguji kelembaban dan suhu tanah dengan cepat. Bagian pengukuran kelembaban dirancang berdasarkan prinsip FDR, dengan mengukur konstanta dielektrik tanah untuk mengukur volume kadar air tanah, bagian suhu mengadopsi elemen resistensi platinum presisi, produk built-in drift calibration dan sirkuit kompensasi suhu, dapat beradaptasi dengan sebagian besar aplikasi. Probe dapat tertanam secara permanen di bawah tanah dan dihubungkan ke data logger untuk pengujian tanpa batas.
* Presisi tinggi
* Respon cepat
* Sifat tanah sedikit mempengaruhi
* Langsung ditanam di tanah
* Banyak digunakan
APLIKASI
* Irigasi pertanian

DIMENSIONS
MOUNTING
1.Testing medium should be with uniform intensity.
2. If surface soil water content measurement, the sensor should be insert into soil vertically. Do not shake the sensor when inserted, otherwise the probe will be blended;
3. If multi-layer soil water content measurement, the sensor should be buried in the soil and parallel to the ground. Make sure the probe not be blended;
4. When removing sensors from the soil, please hold the sensor housing shell and do not forcibly pull on the cable. Soil on probes should be brushed tightly.
5. Please keep the sensor in dry & clean conditions.
