RK500-22 pH Soil (4-20mA and RS485)

Features:

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 values according to the soil conditions.

Usually the pH should be in the range of 6.5-7.5 in soil, this is called neutral soil.

The RK500-22 pH sensor measures the pH value in soil, without the need for professional calibration instruments, complex operation, expensive and difficult to carry equipment.

The device is designed for continuous measurement of soil pH value, suitable for agriculture, sewage treatment plant, chemical industry, printing and dyeing, paper making, pharmacy, electroplating and environmental protection and other fields.
