{"product_id":"bluelab-truncheon-1","title":"Bluelab Truncheon","description":"\u003cp\u003eThe Bluelab Truncheon is a long, rugged handheld meter for checking the nutrient strength of a feed solution. Dip it in and a column of bright lights shows the conductivity of the solution, so a grower can mix to strength, top up and re-check without guesswork or fiddly setup. It needs no calibration and is built for wet work around a reservoir. Two versions share the same design. Bluelab recommend the Standard model for home growers and the Commercial model for commercial growers. The Commercial model's larger scale suits hydroponic setups that need stronger nutrient solutions during certain growth stages.\u003c\/p\u003e\u003cp\u003eMeasuring conductivity is the simplest way to track how much nutrient is in a solution. Dissolved nutrient salts let electricity move through the water, so the conductivity rises as more nutrient goes in. The Truncheon reads on every common scale: EC, CF, ppm 500 (TDS) and ppm 700. It also compensates automatically for the temperature of the solution, so warm and cool batches are compared fairly. It leaves the factory calibrated and needs no calibration from the grower. It detects liquid automatically and shows the result on a scale of bright LEDs. Where the lights dance between two values, the true reading sits between them. The long-format body is designed for mixing and measuring at the same time. In very cold or very hot conditions, stirring the solution with the probe also helps it reach the temperature of the solution sooner.\u003c\/p\u003e\u003cp\u003eOwning a Truncheon is mostly about keeping the probe clean. Bluelab's care guide calls for a clean at least once a fortnight, and more often with heavy use, using one or two drops of an unscented liquid scourer. The white shroud should stay fitted except during cleaning, because readings are incorrect without it. If readings run consistently low, clean the probe first. Power comes from three AA standard or alkaline batteries. Rechargeable batteries are not suitable, and the battery cap must sit fully flush to keep the meter waterproof. Both versions carry a five-year Bluelab warranty for the original purchaser, with proof of purchase. To choose between them, compare the strongest feed you mix against the Standard model's ceiling. If your feeds run above it, the Commercial model carries the same design on to a larger scale.\u003c\/p\u003e","brand":"Bluelab","offers":[{"title":"Commercial","offer_id":48083188449438,"sku":"9421024920135","price":219.99,"currency_code":"AUD","in_stock":false},{"title":"Standard","offer_id":48083188482206,"sku":"9421024920012","price":199.99,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/Bluelab_Truncheon_Standard.png?v=1786424549","url":"https:\/\/www.hydrooasis.com.au\/products\/bluelab-truncheon-1","provider":"Hydro Oasis","version":"1.0","type":"link"}
