Metrix
The AM-2250 series is built on the legacy
of the Shark and 2200 controllers. Like its
predecessors it is designed to be the most
flexible, easy to use, and easy to see multiparameter controller on the market.
Aquametrix AM-2250 Controller
Zero Cards
The AM-2250 comes complete. There are no
extra costs associated with buying boards for
different sensors, or buying components to
achieve NEMA 4X.
Features
• pH, ORP, conductivity & flow parameters
available
• Highly visible large backlit LCD display
• Flexible and easy calibration, including
multi-point conductivity calibration for acids and bases
• Two 4-20mA process output with range
scaling and PID Control
• Universal mounting hardware for surface,
panel and pipe mounting
• Compatible with AquaMetrix models 60-series differential pH/ORP sensors, 500-series
combination style pH/ORP sensors, AS/
AM-series conductivity sensors, and most
pulsed flow sensors
• Temperature or flow totalizer output
• Three control/alarm relays with tempera-
ture or flow totalizer output option
Four Parameters
Select the parameter you wish to measure
from the easy-to-use menu. Choose Conductivity, pH, ORP or Flow. The user interface was
designed under the principle that the user
should not need to read the manual.
Three Relays
The AM-2250 provides control of external devices using its three independent control and
alarm relays. Each relay has adjustable high,
low, and in range set-points, cycle timer with
adjustable on and off times. This feature enables tighter control of batch processes by
eliminating chemical overshoot. Third relay
can be activated by temperature or flow totalizer reading as well.
Analog Outputs
The AM-2250 provides two isolated, independent and scalable 4-20 mA outputs.
One 4-20 mA output can be configured for PID
control. The second 4-20mA output can be
set for process or temperature.
Enclosure
The AM-2250 is packaged in a rugged NEMA
4X polycarbonate enclosure making it ideally
suited for indoor and outdoor heavy-duty applications. A mounting kit is included for surface and panel mounting. The enclosure outline makes panel-mount cutouts simple. Pipe
mounting kits are available.
One Big Display
The AM-2250 features a backlit LCD display can
be seen from a distance. The keypad allows
easy entry of menu items and numeric values.
Calibration
No other controller offers the same combination of flexibility and ease for calibration. The
process value is visible during calibration so
the user knows when it has settled down. Calibration of pH can be with 2 or 3 points. Calibration of conductivity can take as many as 16
points so acids and bases can be measured
through their conductivity.
All Calibration data is stored.
Applications
• Industrial process control, e.g. plating, food
and beverage, chemical processing, pulp &
paper, mining, food and beverage
• Municipal water and wastewater treatment
• Industrial and municipal waste treatment
and Neutralization
• Fume scrubbers
• HVAC, cooling towers and boilers
