Trace-Gas - Model LAS H2O2 -Laser Absorption Spectroscopy Gas Analyzer

FromTRACE-GAS - brand by KNESTEL Technologie & Elektronik GmbH

SHARE

The TRACE-GAS H₂O₂ analyzer combines reliability, fast response and easy handling in one instrument. Developed for a calibration-free and direct measurement of Vaporized hydrogen peroxide (VHP, H₂O₂) in air. The VHP sensor also is resistant to chemicals and has low material adsorption of H₂O₂. Benefit from our nearly maintenance-free analyzer with long lifetime for your VHP measurement with H₂O₂sensor.
