Eco pH Duo +M (Aquaria, Aquaculture)

ECO pH Duo+M is specially designed for Aquaria and Aquaculture.  This meter lets you perform pH and temperautre tests in one go easily, accurately.  No more color comparisons or dripping with color test kits.  Over dosage during adjusting water pH can over load water with harmful chemicals.  With the use of ECO pH+, the user is able to make multiple tests per day and between small dosages during water adjustment. Most importantly, small water adjustment dosages will not shock the fishes which can result in fatalities.  Temperature is another factor to monitor, as higher temperature reduces oxygen in water which can result in fish leaping off water.  With such convenience and assurance, the ECO pH Duo +M far surpasses the many tedious tests of cheaper liquid test kits and at the same time work as a thermometer.  The memory function allows advance user to monitor and track pH and temperature trend over weeks or months.  It is certainly a pH meter value for money!
