ITT Analytics' Instrumentation Is 'Out of this World'

NASA has the company's total organic carbon analyzer and conductivity temperature meter onboard the space shuttle Discovery, which made its last trip to the International Space Station last week.

ITT Corporation announced that its OI Analytical-branded total organic carbon analyzer (TOCA) and WTW-branded VARIO conductivity temperature meter were selected by NASA for inclusion on the final flight of the space shuttle Discovery. The instruments will be used by the crew of the International Space Station (ISS) to measure conductivity and analyze water quality.

The company formed ITT Analytics in March 2010 following the company's acquisition of Nova Analytics.

The TOCA was developed in collaboration with NASA specifically for use on the ISS. It will be used onboard to analyze the organic carbon level in water that has been processed and purified, ensuring it is safe for human consumption in line with SSP 50260, International Space Station Medical Operations Requirements Document.

Possessing innovative electrochemical-oxidation technology, the TOCA maintains excellent long-term calibration stability with minimal maintenance. The instrument's color touch-screen display with Windows CE-based user interface simplifies instrument set-up and access to data, trending, and diagnostic screens.

The crew will use the conductivity temperature meter to measure conductivity of water within the ISS Oxygen Generation Assembly (OGA) to ensure the continued operation of the station's oxygen generation system. The instrument's design makes it particularly suited for this demanding application while its touch screen enables all functions to be performed single-handedly.

"ITT Analytics is delighted that two of its instruments will be playing a key role in Discovery's final mission," said Chris McIntire, president of ITT Analytics. "The instruments' high precision, robust nature and accessibility will ensure superior performance in the ISS's demanding environment."

Discovery lifted off for its final mission on Feb. 24. For more information about NASA, the ISS and the Discovery mission, visit
