Its \u003cstrong\u003eautomatic temperature compensation\u003c\/strong\u003e corrects every conductivity reading against the temperature it was taken at, so a tank sitting at 16°C and one sitting at 24°C give you numbers you can genuinely compare against your feed chart. It arrives \u003cstrong\u003efully calibrated\u003c\/strong\u003e with batteries fitted, so it is ready to use straight out of the box.\u003c\/p\u003e\u003cp\u003eBuilt for daily grow room handling, the housing is \u003cstrong\u003eIP67 waterproof\u003c\/strong\u003e and shrugs off splashes and wet hands. A \u003cstrong\u003ecalibration indicator\u003c\/strong\u003e confirms the meter is reading correctly, a \u003cstrong\u003elow battery indicator\u003c\/strong\u003e warns you before readings start to drift, and the pen powers itself down after eight minutes to protect the cells. Two simple buttons switch between EC, Celsius and Fahrenheit. Crucially the \u003cstrong\u003eelectrode is replaceable\u003c\/strong\u003e, so when the probe eventually wears you swap a part rather than buying a whole new meter.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEC and temperature in one instrument\u003c\/strong\u003e — one pen instead of two on the bench\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic temperature compensation\u003c\/strong\u003e keeps EC honest across \u003cstrong\u003e0°C to 50°C\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully calibrated out of the box\u003c\/strong\u003e, with \u003cstrong\u003e3 x AG-13 batteries\u003c\/strong\u003e included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaceable electrode\u003c\/strong\u003e extends the meter's working life for years, not months\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 waterproof housing\u003c\/strong\u003e survives reservoirs, drips and wet hands\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibration and low-battery indicators\u003c\/strong\u003e flag when the meter needs attention\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto power-off after 8 minutes\u003c\/strong\u003e so a forgotten pen does not flatten its batteries\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFeeding Blind Leads to Weak Roots and Slow Growth\u003c\/h3\u003e\u003cp\u003eNutrient strength is the single easiest thing to get wrong. Feed too strong and salts build up in the root zone, drawing moisture back out of the roots and causing tip burn, poor nutrient uptake and stalled growth. Feed too weak and plants run short of the elements they need, which shows up as pale leaves, slow growth and disappointing yields. Neither problem announces itself until the damage is already visible. An EC reading before every feed turns that guesswork into a number, and the temperature reading alongside it flags a reservoir running too warm — the condition that strips dissolved oxygen and invites root disease.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eRemove the protective cover and rinse the electrode with distilled water, then dry it off.\u003c\/li\u003e\n\u003cli\u003ePress the \u003cstrong\u003eOn\/Off\u003c\/strong\u003e button to wake the meter.\u003c\/li\u003e\n\u003cli\u003eInsert the pen upright into the solution up to the marked edge and stir gently.\u003c\/li\u003e\n\u003cli\u003eWait a few seconds for the reading to settle before recording it.\u003c\/li\u003e\n\u003cli\u003ePress the \u003cstrong\u003eC\/F\u003c\/strong\u003e button to switch between Celsius and Fahrenheit.\u003c\/li\u003e\n\u003cli\u003eRinse the electrode with clean water after every use, then power the meter off.\u003c\/li\u003e\n\u003cli\u003eRe-check calibration periodically against a \u003cstrong\u003e1.4 EC\u003c\/strong\u003e reference solution.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003eEC range: 0.0 - 19.9 mS\/cm\u003c\/li\u003e\n\u003cli\u003eTemperature range: 0°C - 50°C (32°F - 122°F)\u003c\/li\u003e\n\u003cli\u003eEC resolution: 0.1 mS\/cm\u003c\/li\u003e\n\u003cli\u003eTemperature resolution: 0.1°C (1.0°F)\u003c\/li\u003e\n\u003cli\u003eEC accuracy: ± 2% F.S.\u003c\/li\u003e\n\u003cli\u003eTemperature accuracy: ± 0.5°C\u003c\/li\u003e\n\u003cli\u003eTemperature compensation: automatic, 0°C - 50°C\u003c\/li\u003e\n\u003cli\u003eCalibration: EC 1-point auto at 1.4 EC\u003c\/li\u003e\n\u003cli\u003eCalibration indicator: yes\u003c\/li\u003e\n\u003cli\u003eLow battery indicator: yes\u003c\/li\u003e\n\u003cli\u003eWaterproof rating: IP67\u003c\/li\u003e\n\u003cli\u003eAuto power-off: after 8 minutes\u003c\/li\u003e\n\u003cli\u003ePower supply: 3 x 1.5V AG-13 button cell (included)\u003c\/li\u003e\n\u003cli\u003eElectrode: replaceable\u003c\/li\u003e\n\u003cli\u003eDimensions: 220 x 40 x 40 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 102 g\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Aqua Master Tools","offers":[{"title":"Pen Meter","offer_id":53548947898634,"sku":"AMT-E50PRO-EC-TEMP","price":48.85,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/AquaMasterToolsE50ProEC_TemperatureMetermain.jpg?v=1787402433","url":"https:\/\/hydrocropshop.co.uk\/products\/aqua-master-tools-e50-pro-ec-temp-meter","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
