The combination soil meter is a simple and cost-effective addition for anyone who wants to check their plants quickly and easily. It measures soil moisture and the pH value directly in the root zone and is particularly well suited for use in the Rohner Planter system. In addition, the soil meter measures sunlight exposure. Thanks to the integrated solar cell, it works without batteries and requires no maintenance. Before winter, it is simply pulled out, cleaned and stored safe from frost. The device provides quick guidance in everyday use, but does not replace the precise and permanently automatic monitoring of our professional Complete System with sensor.
