mA
RS-485 signal: support Modbus Protocol (baud rate 9600 can be set, address 0-255)
(settable) response time: < 1s, measurement stability time: 1s, exchange accuracy: < 3%
Retest error: < 1% measurement principle: frequency domain reflection principle (FDR principle) material: ABS engineering plastic, 4-Probe (stainless steel) ring structure, with anti electrolysis, corrosion resistance and other characteristics, high compressive strength, which can be directly applied to harsh environments such as saline alkali soil. It can be calibrated by drying method in code for agricultural meteorological observation, which can measure the area in the ring, with large measurement area High stability measurement area: 90% of the influence is around the central probe with a diameter of 3cm and a length of 6cm
