Instrumentation Selected by NASA for Discovery’s Final Flight
Jun 01 2011
ITT Corporation announced that its OI Analytical branded total organic carbon analyser (TOCA) and WTW branded VARIO® conductivity temperature meter have been 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 analyse water quality.
The OI Analytical TOCA from ITT Analytics was developed in collaboration with NASA specifically for use on the ISS. The TOCA will be used on-board to analyse 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 providing accurate and dependable data with minimal maintenance. The instrument’s colour touch-screen display with Windows® CE-based user interface simplifies instrument set-up and access to data, trending and diagnostic screens.
The ISS crew will also use the WTW VARIO conductivity temperature meter from ITT Analytics 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 robust and ergonomic design makes it particularly suited for this demanding application while its innovative touch screen enables all functions to be performed singlehandedly.
In addition to offering a high level of precision when measuring conductivity, temperature, specific resistance, salinity or TDS (total dissolved solids) of a solution, the meter’s pure water conductivity cell with flow-through vessel enables users to make rapid and easily controlled measurements.
“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."
