Sensors - Marlox Thermocouples
Metal Sheathed - Inert Oxide Insulated
Marlox is metal sheathed, inert oxide insulated thermocouple cable from
marlin manufacturing Corporation. Available within ANSI/ASTM calibratioin
tolerances and with various types of sheath alloys. Marlox can
be ordered as complete fabricated assemblies or in random lengths.
Drawn to final size and fully annealed standard Marlox, single
or dual thermocouple element, is moisture-proof, pressure resistant,
accurate, bendable and weldable. Quality control procedures insure
that all thermocouple material is tested for adequate insulation
resistance. All certified Marlox stock is checked for ANSI/ASTM
limits of error conformance by lot sampling in our quality control
metrology laboratory, which is certified traceable to the National
Institute of Standards and Technology (NIST) and ISO
17025 NVLAP accredited (Lab Code 2000512-0). Post assembly
certified traceable calibration is available upon request.

General Selection Parameters
The conditions of measurement determine the type of thermocouple used. Temperature, atmosphere, protection, response, and service life should be considered. The following descriptions serve as a guide to selection.
- Thermocouple Type
- Select the thermocouple type that will be capable of operating in your application temperature range.
- Sheath Alloy
- Select a sheath alloy that will withstand the temperature and possible corrosives of your application.
- Sheath Size
- Use the thermocouple size that will withstand the rigors of your application, but with minimal effect on it.
- Junction Type
- Select the junction that will give the protection and response characteristics that you require.
- Marlox Transition and/or Extension Types
- Transition and Extension Types.
- Fitting or Mounting Type
- In order to attach and/or seal the thermocouple in your application, you can use a fitting - braze, weld or solder it in place.
- Terminal Type
- For connection to instruments, various terminations and extensions are available.
Specialty Marlox® Items
Marlin offers thermocouples utilizing noble metals and exotic materials for the sheath, thermocouple wires and insulation. These thermocouples are fabricated utilizing hard-fired refractory oxides and incorporate the highest manufacturing syandards to insure performance and to prevent contamination.
Marlox is available for your fabrication from our stock. Ends are cut square and moisture sealed.
