The Rika RK500-22 pH sensor measures the pH value. The RK500-22 is a great solution without the need for professional calibration instruments. The RK500-22 can be used for continuous measurement of soil, waste water pH value, etc. and is suitable for agriculture use, sewage treatment plants, the chemical industry, printing and dyeing, paper making, electroplating and environmental protection.\n\u003cbr\u003e\u003cbr\u003e\nNeed help selecting the right IoT solution?\n\u003cbr\u003e\u003cbr\u003e\nGo Wireless NZ now offers a full consultation service through its subsidiary company \u003cb\u003e\u003ca href=\"https:\/\/www.scopious.co.nz\/\" target='_new\"'\u003eScopious IoT Ltd\u003c\/a\u003e\u003c\/b\u003e to help you to start building your IoT network today.
