The Shark controller and Shark TX transmitter replaced all four 2200 models with one multi-parameter, single-input analyzer. After 10 years of a stellar track record the Shark and Shark TX have been replaced by the AM-2250 and AM-2250TX. With greater measurement accuracy and features that you actually need these two new models will set a new standard for durability and ease of use for the next decade.
The AM-2300 multi-parameter, multi-input controller is the first and only web-enabled analyzer that brings SCADA functionality to a small package that anyone can configure and use. One day all controllers will work like it.
