52250-series Operating Manual rev 2.01 Introduction1.1 Third in a Long History of ControllersThe AM-2250 multi-parameter controller is the third-generation controller built on the 30-yearAquaMetrix legacy of building durable and easy-to-use controllers. Many of the 2200 controllers soldthose three decades ago are still in use today in some of the most hostile environments found in industry.Orders continue to come in today for 2200 pH, ORP or conductivity models, years after they entered end-of-life status.The AM-2250 controller, AM-2250TX transmitter and AM-2251 controller. Some of the designimprovements over previous generation analyzers include:• An advanced conductivity measurement design that results in a ten-fold improvement inaccuracy at low and high conductivity values.• Form factor optimized for wall or panel mounting.• Large LCD screen (backlit in the AM-2250 and AM-2251).• A revamped menu structure that is so intuitive that the manual is unnecessary.• The ability to calibrate conductivity solutions in TDS units (mg/l) and % concentration.• Live readings during calibration to determine when the• Three-point calibration for pH to give more accurate pH values over a wide pH range.• Multi-point (<16) calibration routine for conductivity for measurement of acid and baseconcentrations.• PID control.1.2 Differences between the AM-2250, AM-2250TX and AM-2251The AM-2250 and AM-2251 are AC-powered controllers consisting of three relays and two 4-20 mAoutputs. The AM-2250TX is a transmitter version of AM-2250. It is loop-powered and does not containthe power-relay circuit board. Because of power constraints the LCD is not backlit.
