Product Description

Rika Rk500-12 4-20mA RS485 Modbus Output Online Liquid pH Transmitter for Wastewater

 

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.

ELECTRODE MAINTENANCE

PH electrode is not used at ordinary times and can be soaked in 3mol/l KCL solution or saturated KCL solution. It is strictly prohibited to immerse the electrode in distilled water and deionize the water or tap water with minimal plasma content.If the PH electrode is contaminated with inorganic substances, it can be cleaned with 0.1mol/l Hcl or NaOH solution for a few minutes and then washed with distilled water. If the PH electrode is contaminated with organic substances, it can be cleaned with alcohol or acetone and then cleaned with distilled water.(note: the protective cap before the electrode should be removed when using);

Clean the electrode with tap water every 3 months or 6 months according to the working environment.
