GDS CH2O formaldehyde dynamic standard gas generator Introduction: The GDS-CH2O formaldehyde dynamic standard gas generator meets the requirements of the "Verification Regulations for Formaldehyde Gas Detectors" (JJG1022-2016). The system adopts a trimeric formaldehyde diffusion cracking system and a dynamic gas distribution system to generate formaldehyde standard gas. characteristic: The host is equipped with a gas mass flow controller, permeation tube furnace, permeation tube, electrical components, and measurement and control software. The trimeric formaldehyde diffusion tube contains a certificate of standard substance, and the dynamic gas distribution system uses the most advanced measurement and control technology currently available internationally, The equipment is stable and reliable, with high configuration accuracy. The principle of gas distribution is the mass mixing method, The 5 core components are gas mass flow controllers, which are widely used internationally and traceable. The system is equipped with two channel gas mass flow controllers, which can generate various concentrations of formaldehyde standard gas in real time. Technical parameters: Uncertainty of formaldehyde diffusion tube expansion:< 2.1% Formaldehyde gas concentration range: 0-1.5 µ mol/mol Expanded uncertainty of formaldehyde gas:< 2% Minimum Resolution: Gas Distribution Minimum Concentration: 10 ppb Adopting the principle of permeation diffusion and high-precision mass flow mixing method Core component flow controller: using original Parker MFC flow from the United States Output flow range: 5000 ml/min (non-standard product, customized according to needs) Gas input pressure: 0.4 MPa Communication method: WIFI/INTERNET/RS232 Adopting gas mixing technology PT-GDMS System display: 7-inch LCD touch screen Operating temperature: 5 ℃ -40 ℃ Power requirements: AC220V 50Hz
