With a large backlit display, you can clearly read results even in dim environments, making it ideal for RO and deionized water setups, drinking water applications, aquariums, hydroponics, and more. Dual probes continuously monitor water quality at the input and output points, helping you spot membrane breakthrough, leaks, or shifts in water conductivity before problems arise.\u003c\/p\u003e \u003cp\u003eBuilt for reliability, the DM-3 features shielded sensor cables to minimize interference and diagnostic messaging to simplify troubleshooting. It ships with two 1\/4″ T-fittings (with options for 3\/8″ or 1\/2″ fittings) and a dual sensor (SP-3) setup for quick, secure connections. The combination of robust microprocessor control and straightforward calibration makes this monitor a dependable choice for precise, repeatable readings across drinking water, aquariums, hydroponics, and more.\u003c\/p\u003e \u003cp\u003eKey benefits include automatic power saving (auto‑off after 3 minutes), factory calibration with a 342 ppm NaCl solution, and digital calibration for repeatable accuracy. The device is designed to provide clear TDS readings for both feed and product water, with diagnostic error messaging to help you quickly identify and address issues. Shielded cables and a compact form factor keep installation clean and readings stable in a variety of environments.\u003c\/p\u003e \u003ch2\u003eBenefits \u0026amp; Tips\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eMonitor input vs. output water in real time to verify RO membrane performance and detect breakthrough or leaks.\u003c\/li\u003e \u003cli\u003eKeep aquarium or hydroponic water within target TDS ranges to protect aquatic life and optimize nutrient delivery.\u003c\/li\u003e \u003cli\u003eUse the shielded cables and dual probes to minimize interference for accurate, repeatable readings across different setups.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eProduct specifications\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eEC Range: 0–9999 μS \/ 0–9.99 mS\u003c\/li\u003e \u003cli\u003eTDS Range: 0–5000 ppm \/ 0–5 ppt\u003c\/li\u003e \u003cli\u003eEC Resolution: 0.1 μS (0–99.9), 1 μS (100–999), 10 μS (1000–9990), 0.01 mS (0.00–9.99)\u003c\/li\u003e \u003cli\u003eTDS Resolution: 0.1 ppm (0–99.9), 1 ppm (100–999), 10 ppm (1000–5000), 0.01 ppt (0.00–5.00)\u003c\/li\u003e \u003cli\u003eAccuracy: ±2%\u003c\/li\u003e \u003cli\u003eATC (Temperature Compensation): 0.0–60.0 °C\u003c\/li\u003e \u003cli\u003eTDS Conversion Factor: NaCl (0.5 avg.)\u003c\/li\u003e \u003cli\u003eCable Length: 1.2 m \/ 3.9 ft, shielded\u003c\/li\u003e \u003cli\u003eSensor: Dual, 1\/4″ diameter for quick-connect fittings (model SP-3, included)\u003c\/li\u003e \u003cli\u003eDisplay: DIGITAL with Backlight\u003c\/li\u003e \u003cli\u003ePower Source: 2 x AA batteries\u003c\/li\u003e \u003cli\u003eSize: 11.6 × 1.9 × 7.0 cm (4.6 × 0.7 × 2.8 in)\u003c\/li\u003e \u003cli\u003eWeight: 225 g (7.9 oz)\u003c\/li\u003e \u003cli\u003eFittings: Comes with two 1\/4″ T-fittings (option for 3\/8″ or 1\/2″ available)\u003c\/li\u003e \u003cli\u003eOrigin: Mainland China\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003ePackage includes:\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eDM-3 Dual TDS Monitor\u003c\/li\u003e \u003cli\u003eDual SP-3 sensors\u003c\/li\u003e \u003cli\u003eShielded sensor cables\u003c\/li\u003e \u003cli\u003eTwo 1\/4″ T-fittings (with optional sizes available)\u003c\/li\u003e \u003cli\u003e1.2 m shielded cable assembly\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch2\u003eWarnings \/ Reminders\u003c\/h2\u003e\n\u003cul\u003e \u003cli\u003eAuto-Off function conserves power by shutting the unit off after 3 minutes of inactivity.\u003c\/li\u003e \u003cli\u003eFactory calibration uses a 342 ppm NaCl solution; digital calibration is available for precise adjustments.\u003c\/li\u003e \u003cli\u003eEnsure proper connection of the 1\/4″ fittings to maintain accurate readings and avoid leaks.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e \u003cp\u003eProviding quality and trusted service since 2002 at intercyprus.com.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"InterCyprus Trading Ltd","offers":[{"title":"DM-3","offer_id":54674621497686,"sku":"1005007773834158-DM-3","price":114.24,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/Se4a1acee9ef54df39b4c2c54974e1c22t.webp?v=1784483409","url":"https:\/\/www.intercyprus.com\/products\/tds-ec-water-meter-dual-probe-online-tds-ec-detector-input-output-digital-water-quality-monitor-for-tap-water-fish-tank-5000ppm","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
