Overview
Gasboard-3800GHG is a portable greenhouse gas emission analyzer using patented micro-flow NDIR dual-chamber sensors to measure CO2, CH4, N2O and CO in flue gas, with ranges from 200 ppm and accuracy up to 1% F.S. With an integrated heated probe, portable conditioning unit and optional temperature, pressure and flow measurement, it can calculate emission rates and totals.
Key Features
- PCT approved product based on micro-flow NDIR technology to measure low concentration gases. (US Authorization No.: US11079322);
- One analyzer can simultaneously and continuously measure up to five gases such as CO2, CH4, N2O, CO and O2;
- CO2, CH4, N2O, CO can choose the patented Microflow NDIR technology, the range can be as low as 200ppm, accuracy up to 1%F.S.;
- Small drift, anti-moisture interference, good long-term stability;
- Dual beam NDIR technology can be used to measure CO2 and CO for flexible collocation for medium and high concentration measurement requirements;
- Both digital and analog signal output functions, simple data management;
- Portable instrument, and equipped with high-performance sampling probe and pretreatment device.
