This extends the probe's lifespan while enhancing output signal stability. The TDS probe features a waterproof design, allowing for long-term immersion in water during measurements\u003c\/li\u003e\n\u003cli\u003eEasy to Use: simple connection via Gravity 3-pin interface, plug and play without solderin with sample code\u003c\/li\u003e\n\u003cli\u003eGood compatibility: This TDS sensor supports 3.3~5.5V wide voltage input, and 0 ~ 2.3V analog voltage output, which makes it compatible with a 5V or 3.3V control system or board\u003c\/li\u003e\n\u003cli\u003eNOTE: While the TDS probe tip and cable are waterproof and submersible, the connection interface and signal converter board are NOT waterproof. Avoid exposing these components to water during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"DFROBOT","offers":[{"title":"Default Title","offer_id":49018181451928,"sku":"B086GX2539","price":17.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0742\/5569\/6024\/files\/6192ip0BC4L._SX522.jpg?v=1778363702","url":"https:\/\/greenateliershop.com\/products\/b086gx2539","provider":"Green Atelier","version":"1.0","type":"link"}
