Thermo Scientific Miran Sapphire 205B is a family of portable, lightweight infrared instruments that can monitor ambient air in workplace environments for the purpose of detecting the presence of gases. Thermo Scientific Miran Sapphire 205B exclusive design of the wavelength generator filter allows accurate and fast wavelength selection separating the MIRAN SapphIRe Analyzer from other portable gas analyzers.
Thermo Scientific Miran Sapphire 205B contains a single-beam infrared spectrophotometer to specifically and accurately measure many gases with a single unit. Thermo Scientific Miran Sapphire 205B results of this analysis can be displayed in parts per billion (ppb), parts per million (ppm), percent (%), mg/m3, or absorbance units
Thermo Scientific Miran Sapphire 205B models can be configured with two options: intrinsic safety certification and spectral scanning using Thermo Scientific ThermoMatch Spectrum Correlation Software.
Thermo Scientific Miran Sapphire 205B Applications:
- Industrial hygiene monitoring
