About


Martek Instruments, Inc. was established in 1968 as a manufacturer of portable environmental water quality analyzers. Ten years later, Martek expanded into ultrapure water quality analysis when it began developing products for this application with a special emphasis on power generation. The ability to collect, process, and transmit real-time data to system operators make the products Martek supplies ideal for monitoring high purity water environments such as nuclear and fossil fuel power plants, condensate polishing systems and demineralizers, semiconductor and pharmaceutical manufacturing plants, and other industrial applications.

Today, Martek manufacturers not only its own line of ultrapure water quality systems from its Raleigh, North Carolina facility, but offers products and accessories from well-known companies such as Thermo Orion to meet the needs of the scientific and commercial communities. Monitored parameters include:

  • Temperature
  • Conductivity (Specific, Cation, Degassed)
  • pH ORP
  • Dissolved Oxygen
  • Sodium
  • Silica
