Gitest

    Description

    Universal analytical device designed to analyze the composition of exhaled air for diagnostic purposes. Allows you to perform carbon isotopic composition breath tests and measure the content of hydrogen and methane in the exhaled air. The carbon isotope ratio and methane concentration are measured by absorption IR spectroscopy at wavelengths of 4.2 µm, 4.3 µm, and 3.4 µm. Hydrogen and oxygen concentrations are measured by electrochemical sensors.
    The device will be produced in two modifications:

    • Tabletop: up to 30 measurements per day
    • Laboratory: up to 200 measurements per day
