Overview
Gasboard-3800UV is a portable flue gas analyzer combining UV-DOAS, NDIR and electrochemical technology to measure SO2, NO, CO, CO2, HC and O2. With resolution down to 0.1 mg/m³ and no moisture or dust interference, it suits ultra-low emission checks, and it ships with a heated probe, heated line and Peltier conditioning unit.
Key Features
- Based on ultraviolet differential optical absorption spectroscopy technology, DOAS algorithm is adopted through the deep ultraviolet band and different optical path, no moisture absorption, no interference from moisture and dust, no cross interference between measurement gases.
- Low detection limit, resolution up to 0.1mg/m3, it is suitable for ultra-low emission monitoring in the different industrial applications.
- Sensor modular design, good stability with no vibration affect.
- Light source adopts flashing xenon lamp with long life time.
- It is equipped with integrated sampling probe, heating tube, and imported gas conditioning device removes dust and moisture.
- Automatic calculation of air coefficient and combustion efficiency.
- Automatic storage of measurement data.
- Dot matrix printer and USB communication interface to print real-time and historical data, or directly export the stored data to the USB flash drive.
- Stainless steel heating type sampling probe, heating temperature up to 200℃.
- The probe is equipped with SIC filter element for quick replacement.
- Sampling probes are available in different lengths (1 or 2 meters) to suit various industrial applications.
- Heating tube has self-controlled temperature function to keep high temperature of 180℃, it can prevent SO2 gas condensation to loss value.
- Original imported diaphragm pump, flow rate ≤60L/h.
- Gas-water separator to separate liquid water in the sample gas.
- Original Peltier cooler removes gaseous water from sample gas.
- Equipped with corrosion-resistant and pressure-resistant heat exchanger and independent digital PID controller.
- After treating, sample gas dew point:≤4℃, dust accuracy: 0.1μm.
