Compared to the conventional method of mixing soil and water and measuring the supernatant liquid, this method saves a lot of time and effort. Furthermore, since it can measure solutions (liquids) other than soil, it is also useful for nutrient solution management in hydroponic cultivation. This device is a model change product of HI 99121N, and the main changes are as follows. - The status of the pH electrode after calibration can now be displayed on the screen. ・It is now possible to display the calibrated standard solution value on the screen. ・It is now possible to display pH-mV to check the pH electrode. ・IP67 waterproof. The main body is also more durable than the previous model. -The electrode connection part is a quick DIN type, making it easy to connect to the main body. The connection part is also now waterproof.

■Applications

Soil diagnosis in fields, soil and nutrient solution management in agriculture and hydroponic cultivation, pH measurement of rock wool, landscaping, etc.

■Features
