Hanna* Portable Turbidity Meters

Model C114 provides free and total chlorine measurements and EPA-compliant turbidity measurements (turbidity measurements are made using the nephelometric principle according to US EPA 180.1 method and the Standard Method 2130B). Model C102 additionally measures pH, bromine, iodine, iron and cyanuric acid (CYS). All measurements can be performed quickly and reliably with these laboratory-grade, microprocessor-based, handheld field instruments. They will log data for up to 25 measurements with time and date information for later retrieval. With the built-in clock, you can check the last calibration date with the touch of a button. Measurements can be performed using either concentration or relative absorbency of the sample. Units can be calibrated using the factory-programmed calibration points or can be custom calibrated when in colorimetric mode. Two silicone photocell light detectors. Pure green LED. User-selectable auto shutoff at 10, 20, 30, 40, 50 or 60 minutes. Weighs just 18 ounces. 8.7 x 3.2 x 2.6 in. (220 x 82 x 66 mm). Operates approximately 60 hours (or 1000 measurements) on four (1.5V) AA batteries included. Also included are measurement cuvette, cap and instruction manual.
