HANNA D.O. COLORIMETER ++

The world's leading manufacturer of electro-analytical instruments has the right solution to solve the problem of measuring water parameters in an easy, inexpensive and accurate way. Ion specific meters are a simpler alternative to Ion Selective Electrodes and time consuming chemical test kits. Simple reagents are added to each sample to produce a color change that represents the concentration of the measured parameter. Each meter reads this change in color with a silicon photocell and shows the value of the parameter on the large LCD with lab grade accuracy from the powerful microprocessor.
