National Testing Laboratories Ltd., exclusive distributor for Continental Hydrodyne Systems, Inc., introduces Aquaking and EZ-Check colorimeters. Aquaking is pre-programmed to test for 60 different contaminants, while EZ-Check allows customers to custom program up to 14 different contaminants. Both units utilize a patented Curve Fit (CF(TM)) technology, which eliminates the need for factory recalibration. These colorimeters allow for automatic calibration every time you use the instruments. The reagents for these units are delivered differently than most because they come in the vials used to collect the sample. Ideal for the water treatment professional, the easy-to-use units are portable, durable and carry a full three-year [email protected]
