The 1st category reference instrument - a complex for dynamic gas mixing DGK-NV for verification, calibration and testing of gas analytical instruments and systems of different types of oil vapors. The system is ideal for organizations with accreditation for verification.

DGK-NV is a dynamic gas mixer and provides preparation of binary gas mixtures by dynamic mixing two gas streams - gas mixture obtained by bubbling air through the target component in a liquid phase and a diluent gas.

Maximum permissible error of DGK-NV for petroleum vapor ± 2% LEL.
