The Environmental Express CL 200 chlorine colorimeter is a single-parameter instrument for measuring the concentration of free and/or total chlorine in water samples. Its rugged, handheld design makes it adaptable for field use or in laboratory settings. With stored calibration ranges specific to chlorine measurement and a simplistic user interface, the meter is easily operated by technicians at any experience level, ensuring accurate results without the need for retesting.
Model CL 200 colorimeter is supplied ready to use with two preprogrammed testing ranges for free, total, and combined chlorine. Both ranges use the DPD testing method. When the instrument is turned on, it will automatically display the last test used with readings in ABS or %T units. Simply select the measuring range, prepare your sample, and test. Primary and secondary standards are available for on-site verification of instrument performance
