ZR-3211H UV DOAS Method GAS Analyzer
Overview
DOAS UV-based In-Situ Gas Monitor for Process Control, Compliance Monitoring. It can measure the concentration of SO2, NO, NO2, CO, CO2, O2, H2S, NH3. The water in the flue gas won’t affect the accuracy. This product is especially suitable for high humidity and low sulfur conditions. The instrument is designed to be integrated with the host and convenient for sampling. It can be used by environmental departments to test the gas concentration and emission from boilers, and can also be used in industrial and mining enterprises to measure the concentration of various harmful gases.
Applications
• Measure the O2 of gas and excess air coefficient.
• Evaluate and calibrate the accuracy of continuous flue gas measuring instruments.
• Other applicable occasions.
Standards
• GB13233-2011
• GB/T37186-2018
• HJ 973-2018
• HJ/T 397-2007
• HJ 1045-2019
• JJG 968-2002
Features
• Tested by UV-DOAS, measure 8 gases (SO2, NO, NO2, CO, CO2, O2, H2S, NH3) from the flue. The water in the flue gas won’t affect the accuracy. This product is especially suitable for high humidity and low sulfur conditions.
• Equipped with a pitot tube and smoke temperature sensor, it can measure smoke temperature flow rate and moisture.
• Integrated with the host and probe, convenient to operate.
• Built in a lithium battery, can work at least 3 hours in fully charged situation.
• Built in a condensate water removal module, ensure the sensor service life.
• Equipped with titanium alloy vacuum heat insulation pipe, suitable for high temperatures in the flue.
• Check and export the data by USB (excel table). Users can print the data via a blue tooth printer.
