The NexSys® control system is the latest in a long line of reliable, easy to use controllers from Lakewood Instruments. The NexSys® control system uses the latest in microprocessor technology with a 5.7” Color Touch Screen interface for a high level of application flexibility. All features, parameters, settings, and functional
requirements to operate, program, and monitor the NexSys® control system are accessible from the touch screen and DO NOT require the use of an external input, PC or device to operate or access.
The NexSys® control system even includes On-Board Help Screens with wiring, programming, and maintenance instructions.
The NexSys® control system comes standard with the following system interfaces and DMX outputs:
LON EIA 709 FTT10, BACnet IP, and MODbus TCP. The unit comes from the factory ready to integrate readings into a BAS, including: The state of any installed relay (On/Off) , Water meter readings, Conductivity readings, Additional sensor readings (ph, ORP), sensor alarms, Additional 4-20mA input readings, Flow condition, and other digital inputs.
The NexSys® control system comes standard with Ethernet capability through a browser (HTML5) interface that allows 100% access to all features and control parameters of the controller.
The NexSys® control system has an astounding
array of built-in features such as:
• LonWorks, MODbus, and BACnet communications interface
• Ethernet capability through an HTML interface
• The capability to send E-service reports to a subscribed service
• The ability to display operating values with time and date stamps on color coded graphs with zoom and scroll features
• Up to eight active sensor inputs: 2 tower cond, 2 M/U cond, pH and ORP
Trace chemistry capable
• Two water meter inputs with field expansion capability to four
• Enclosure is NEMA 4X rated
• Two flow switch inputs configurable to any relay output
• Ability to add up to eight 4-20mA input readings
• Ability to add four digital inputs
• Ability to mount every sensor/input up to 400 meters away from the controller via 4-wire twisted pair
• Ability to control the chemistry in two towers at the same time
• Six relay outputs expandable to ten relay outputs for user configurable operations such as:

The Yamatho Coupon Rack Kit allows for an economical way to build a corrosion coupon rack. The kit comes complete with everything you need (including Teflon tape) to assemble your own coupon rack.
The corrosion test rack simplifies the procedure for establishing a corrosion monitoring program. The coupon rack kit consists of ¾” or 1” threaded PVC schedule 40 clear PVC pipe and PVC fittings. The kit is easily assembled via threaded connections and an easy to follow instruction guide. This kit also includes (4) foam covers to minimize exposure to sunlight.
Four test coupon holders are provided so that multi-metallic systems can be tested. An inline 5 or 12 GPM Eddington flow regulator is incorporated into the assembly for
maintaining constant water velocity. A variable in-line flow meter is also available as an option for critical measurement of water velocities. An optional clear Y-strainer is available to help maintain water velocity through the flow meter and pipe rack.
The corrosion test rack is designed according to ASTM designation D2688-70 which specifies the monitoring of corrosivity of water in the absence of heat transfer (weight loss methods).
Made in the USA.
