EC meters are more stable but should be verified against a known reference solution weekly. Bluelab Digital EC Meter uses two-point calibration for pH (4.0 and 7.0 buffer solutions) and single-point calibration for EC (2.77 mS\/cm standard). Regular calibration is the single most important factor in measurement accuracy.\u003c\/p\u003e\n\u003ch3\u003eHow do I store Bluelab Digital EC Meter properly?\u003c\/h3\u003e\n\u003cp\u003eAlways store pH probes wet — never allow the probe tip to dry out as this permanently damages the glass membrane. Use the probe storage solution supplied with Bluelab Digital EC Meter or Bluelab KCl storage solution. EC probes are more robust but should also be rinsed with clean water after each use. Store Bluelab Digital EC Meter at room temperature away from direct sunlight.\u003c\/p\u003e\n\u003ch3\u003eWhat should I do if Bluelab Digital EC Meter is reading incorrectly?\u003c\/h3\u003e\n\u003cp\u003eFirst, recalibrate using fresh buffer solutions — old or contaminated calibration fluid is the most common cause of inaccurate readings. Rinse the probe thoroughly with deionised or distilled water between calibrations. If readings are still inconsistent after recalibration, check the probe for physical damage or contamination. Most probes have a service life of 12–18 months with proper care.\u003c\/p\u003e\n\u003ch3\u003eIs Bluelab Digital EC Meter waterproof?\u003c\/h3\u003e\n\u003cp\u003eCheck the IP rating listed in the product specifications. Most handheld meters are splash-proof but not designed for submersion. Take care when measuring in deep reservoirs to avoid dropping the unit. Bluelab Digital EC Meter is designed for hydroponic nutrient solution testing — it is not rated for outdoor or continuous immersion use.\u003c\/p\u003e\n\u003ch3\u003eDoes Bluelab Digital EC Meter ship fast within Australia?\u003c\/h3\u003e\n\u003cp\u003eYes — Bluelab Digital EC Meter ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.\u003c\/p\u003e","brand":"Bluelab","offers":[{"title":"Default Title","offer_id":43187318718527,"sku":"EC-METER-PEN","price":144.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/6898\/8479\/files\/BLECPEN-Bluelab-EC-Pen_1000x1000_Grey-600x600_1.png?v=1777436895","url":"https:\/\/apexgrow.com.au\/products\/digital-ec-meter-conductivity-temperature-pen-australia","provider":"Apex Grow","version":"1.0","type":"link"}
