Portable hydrogen gas analyser VG-2

   This gas analyser is based on MIS (metal-insulator-semiconductor)-sensor. VG-2 is applicable in the fields of: geology (gases sources researches), technics (detecting hydrogen solvated in metals and liquids), microelectronics (technological processes control) and medicine (hydrogen breath test). Warranty period - 1 year.
