The H600 Pro Handheld Substrate Meter is the professional 5-in-1 tool that measures pH (0.1–14.0), EC (0.0–19.9 mS\/cm), TDS (0.0–19.99 PPT), PPM (0–1999 on 700 scale) and temperature (0–50 °C) right in soil, coco, peat or other moist media. User-friendly interface lets you switch parameters instantly, while the built-in calibration indicator reminds you after 30 days to keep readings accurate. 2-point auto pH calibration (4.0 \u0026amp; 7.0) and 1-point auto EC cal make setup fast and reliable, with automatic temperature compensation ensuring consistency across SA’s variable grow temps. IP67 waterproof electrodes handle direct substrate probes or liquid dips, the durable meter comes with a protective carrying case for safe transport between tents or sites, and a 9V battery (included) powers extended sessions. Compatible with Aqua Master substrate electrodes — perfect for deep pot checks, slab testing or liquid reservoirs. Reliable, portable and built for daily use — this meter helps you maintain ideal parameters for stronger roots, better uptake and maximum yields in any medium.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e5-in-1 substrate \u0026amp; liquid testing – pH, EC, TDS, PPM \u0026amp; temperature in one device\u003c\/li\u003e\n\u003cli\u003e2-point auto pH calibration – quick, accurate setup at 4.0 \u0026amp; 7.0\u003c\/li\u003e\n\u003cli\u003e1-point auto EC calibration – simple \u0026amp; reliable for nutrient solutions\u003c\/li\u003e\n\u003cli\u003eCalibration reminder after 30 days – ensures ongoing precision effortlessly\u003c\/li\u003e\n\u003cli\u003eIP67 waterproof electrodes – safe for direct substrate probing \u0026amp; reservoir use\u003c\/li\u003e\n\u003cli\u003eIncluded carrying case \u0026amp; 9V battery – portable \u0026amp; ready for grow-room fieldwork\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003epH Range: 0.1 – 14.0\u003c\/li\u003e\n\u003cli\u003eEC Range: 0.0 – 19.9 mS\/cm\u003c\/li\u003e\n\u003cli\u003eTDS Range: 0.0 – 19.99 PPT\u003c\/li\u003e\n\u003cli\u003ePPM Range: 0 – 1999 (700 scale)\u003c\/li\u003e\n\u003cli\u003eTemperature Range: 0 – 50 °C (32 – 122 °F)\u003c\/li\u003e\n\u003cli\u003eResolution: pH ±0.1; EC 0.1 mS\/cm; TDS 0.01 PPT; PPM 10; Temp 0.1 °C (1.0 °F)\u003c\/li\u003e\n\u003cli\u003eAccuracy: pH ±0.1; EC\/TDS ±2% F.S.; PPM 10; Temp ±0.5 °C (±1 °F)\u003c\/li\u003e\n\u003cli\u003eTemperature Compensation: Automatic 0 – 50 °C\u003c\/li\u003e\n\u003cli\u003eCalibration: pH 2-point auto (4.0 – 7.0); EC 1-point auto\u003c\/li\u003e\n\u003cli\u003ePower: 1 × 9V battery (included)\u003c\/li\u003e\n\u003cli\u003eWaterproof Rating: Electrodes IP67; Meter IP62\u003c\/li\u003e\n\u003cli\u003eDimensions: 210 × 120 × 60 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 430 g\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HydroGarden","offers":[{"title":"Default Title","offer_id":43842800353368,"sku":"AQU008","price":6280.0,"currency_code":"ZAR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/1510\/3832\/files\/h600-pro-handheld-substrate-meter-4938-en-G.png?v=1773312986","url":"https:\/\/pot-tentialgrows.co.za\/products\/h600-pro-handheld-substrate-meter","provider":"Pot-tential Grows","version":"1.0","type":"link"}
