Rika Rk500-22 Online Realtime Monitoring RS485 Modbus Soil pH Sensor Probe
Product Description
The soil contains many substances such as organic acid, inorganic acid, alkali and salt, due to the different content of various substances, so the soil shows different ph value.Usually the pH in the range of 6.5-7.5 soil is called the neutral soil.RK500-02 pH sensors measure the pH value should be a good solution without professional calibration instruments, complex operation, expensive and difficult to carry, can be for continuous measurement of soil, waste water pH value, suitable for agriculture, sewage treatment plant, chemical industry, printing and dyeing, paper making, pharmacy, electroplating and environmental protection and other fields.
