MMI provides a wide variety of equipment instrumentation that can be used with virtually any application including single-loop and dual-loop atmospheric or temperature controllers.

Instruments for Heat Treat Featuring MMInet Ethernet Connectivity and EasyLink OPC Compatability

Are you frustrated by slow or ineffective service, angered by limited or non-existent phone support, or tired of winding up in some big company's "voice mail jail"?

Marathon works with demanding companies that need the highest quality, longest-lasting instrumentation available; companies that require fast technical support, overnight service and 365 days a year of product availability. 

Since we manufacture all of our instruments at our Cincinnati factory, we are able to provide immediate troubleshooting and replacement; the foreign-made stuff that other companies paste their name on simply can't provide that level of support. 

Do you really want to wait days or weeks just to find out what is wrong when your process is down?

Unlike mass-produced instrument offerings, all Marathon instruments come with a full, 18-month warranty. Even more valuable to the end-user is Marathon's free phone support for the duration of the warranty period. No more endless phone menus and frustration trying to find someone who can solve your problem at some giant company. With Marathon Instruments, you'll be doing business with the manufacturer, not a reseller or distributor. With Marathon you're working with a company that knows who you are and will do what it takes to keep you running.

CarbonSender - Carbon / Temperature Transmitter with Probe Maintenance (manufactured in Cincinnati, Ohio)

The CarbonSender transmitter provides a cost-effective solution for carbon potential and temperature transmission (4-20 mA) to your PLC or SCADA system. This DIN rail module provides full probe maintenance / probe verification functions and can be integrated with Marathon's QuadBox to provide reference air, verification gas and probe maintenance for up to four probes in a single enclosure.

DualPro/MultiPro (manufactured in Cincinnati, Ohio): The DualPro and MultiPro are dual-loop process controllers. Both include calculations for various process variables including carbon atmosphere, dew point, and percent oxygen. Exceptional flexibility is provided by their ability to execute basic programs, logic programs, and recipe programs. Each comes standard with has four communications ports for powerful networking capability.

10 YEAR DISPLAY WARRANTY ON DUALPRO - STANDARD!

LCD on MultiPro is rated to 158 degrees F for operation and warranted for 2 years - Twice the industry standard for LCD displays!

Standard Features:

  • Up to 200 19-step heat treat cycles
  • Large LED display (Upper display atmosphere PV, lower display temperature)
  • Customer configurable from front display
  • Modbus communications
  • Ethernet TCP/IP connectivity available
Unique Features:
  • 200 background logic programs requiring calculations or decision making
  • Three (3) programmable isolated analog inputs (T/C, 4-20mA, slide-wire or linear voltages available)
  • Four (4) events partitioned as either inputs or outputs (expandable to 68)

VersaPro (manufactured in Cincinnati, Ohio): sets a new standard for value by providing single-loop control with industry-standard compatibility at a cost well below that of competitive units.

Developed for flexibility and value, VersaPro can be factory-configured for control of Carbon Potential, Dewpoint, Temperature, ReDox Potential or Oxygen Concentration. By utilizing a single, cost-effective base platform for each of these tasks, VersaPro lowers the costs of state-of-the-art process control, while raising performance and delivering the highest value in the industry.

With industry standards such as EasyLink OPCTM, Modbus, Ethernet and Marathon Protocol, the VersaPro not only supports your existing systems, but also serves as a future-proof building block as your system grows.

VersaPro also sets a new standard for ease-of-use with its integrated alphanumeric display. Operators no longer have to contend with confusing symbols found on other low-cost controllers. Instead, standard English words provide menu prompts and alarm messages.

CarbPro (manufactured in Cincinnati, Ohio): The CarbPro is a recipe programmable single loop atmosphere controller. The CarbPro can control variables such as % carbon, dew point, or millivolts. Control outputs are available for solenoid valves and motorized valves using either contact, voltage, or current loop. The recipe program can control four internal plus sixteen external input or output events and a slave temperature controller.

Standard Features:

  • Up to 200 19-step heat treat cycles
  • Large LED display (upper display atmosphere PV, set point in lower display)
  • Customer configurable from front display
  • 4 - Events (expandable to 64 events)
  • Ethernet TCP/IP connectivity available

10 YEAR DISPLAY WARRANTY - STANDARD!

UniPro (manufactured in Cincinnati, Ohio): The UniPro is a temperature controller with internal memory for up to 200 19-step recipes, two 4-20mA output, T/C selectable input, 2 Alarm and 2 control contacts, and four on-board events.



EasyLink OPCTM: EasyLink OPCTM from Marathon Sensors, is the industry's first 100% OPC-compliant communications interface. Allowing several lines of Marathon Sensors instrumentation to communicate with virtually any Supervisory Process Control Computer Software Program on the market today, EasyLink OPCTM can help gather real-time, process-critical data from your operation, enabling tighter, more precise control.
