Colorimeter C401 Excellent test-to-test repeatability, auto-ranging and convenient The meters ensure excellent test-to-test repeatability and have autoranging capabilities while using only one-vial-one-sachet per test. :: Fuss-free meter operations Designed for utmost convenience (to be maintenance-free), the meters allow one-time blanking for all parameters and ranges. This value-added feature comes in handy when performing multi-parameter analysis and/or repeat measurements of a sample. The blanking value is stored in memory and retained not only if the meter is switched off, but even if batteries are replaced. Furthermore, no pre-calibration is needed for chlorine and cyanuric acid. :: No detachable parts, no flip covers The meters are designed such that the high-quality customised vials fit perfectly into the sample well. Consequently, no detachable light shields or flip covers are required. :: US EPA-approved DPD method Chlorine measurements are based on the US EPA-approved DPD method, so the results can be reliably used for reporting purposes (subject to local regulatory guidelines). :: High quality reagents Custom-formulated powder reagents provide excellent accuracy, repeatability and stability. They are conveniently packed in properly sealed individual sachets for ease of use. :: Advanced power management The meters are capable of more than three thousand tests on a set of four new ‘AAA’ alkaline batteries. The auto power-off function activates after ten minutes of non-use to conserve battery life. :: Waterproof and lightweight The lightweight meters have a waterproof IP67-rated housing. They float if accidentally dropped in water.
