Huafen-Sunrise (HFSR) is a gas analyzer manufacturer, offering analyzing instrument and complete process gas analysis solutions for industrial and laboratory applications. HFSR was the first company in China to apply the electrochemical and thermoelectric method for the industrial process analysis. Now we provide oxygen analyzer, infrared gas analyzer, thermal conductivity gas analyzer, continuous emission monitoring system and integrated process analysis system for customers. Our instruments are widely applied for analyzing gas of oxygen, hydrogen, carbon monoxide, carbon dioxide, methane, ammonia gas and sulfur dioxide. Our gas analyzer has high precision and can be used in complex conditions with good stability. We can provide custom gas analysis solutions to satisfy client demands.

1. Electrochemical Gas Analyzer SR-2030
3. The oxygen Analyzer SR-2030 is a gas analyzer system which makes use of electrochemical methods to measure continuously the oxygen content in kinds of mixed gases.
1. Electrochemical Gas Analyzer SR-2030Ex
3. The SR-2030EX explosion proof oxygen analyzer has greater shell strength and smaller joint clearance between the components of the shell.
1. Thermal Conductivity Gas Analyzer SR-2050Ex
3. The traditional thermal conductivity gas analyzer has many shortcomings in a low range measurement.
1. Thermal Conductivity Gas Analyzer SR-2050Ex (Flameproof Type)
3. The micro-sensor (MEMS) we use features a high precision and integration micro-processing technology, as well as a high detection accuracy and stable performance.
1. Non Dispersive Infrared Gas Analyzer (NDIR) SR-2000
3. The SR-2000 NDIR infrared gas analyzer can be used to detect the designated gas content in mixed gas backgrounds such as CO, CO2, CH4, SO2, NH3, H2O, NOx and other hydrocarbons.
1. Non Dispersive Infrared Gas Analyzer (NDIR) SR-2000Ex (Flameproof Type)
3. The SR-2000Ex explosion proof infrared gas analyzer can be used to detect the designated gas content in mixed gas backgrounds such as CO, CO2, CH4, SO2, NH3, H2O, NOx and other hydrocarbons.
1. Tunable Diode Laser (TDL) Gas Analyzer SR-2030
3. Tunable diode laser (TDL) gas analyzer utilizes diode laser absorption spectroscopy (DLAS) technique. Compared to other techniques such as NDIR, gas chromatography, the result of DLAS will not be disturbed by H2O.
1. Tunable Diode Laser (TDL) Gas Analyzer SR-2030ExL (Flameproof Type)
3. With an explosion-proof degree sign of Ex d ⅡC T6 Gb, this flameproof type gas analyzer is suitable for the detection of group ⅡA, ⅡB,ⅡC as well as T1~T6 hazardous gases and the mixture of hydrogen and oxygen for hazardous areas of zone 1 or 2.
1. Paramagnetic Oxygen Analyzer SR-2030P
3. With a magneto mechanical sensor inside, the paramagnetic oxygen analyzer is used to carry out continuous oxygen concentration measurement.
1. Paramagnetic Oxygen Analyzer SR-2030ExP (Flameproof Type)
3. Paramagnetic oxygen analyzer adopts a flameproof enclosure. We adhere to the principle that an explosion proof oxygen analyzer should have excellent shell strength and maximum surface temperature.
1. Gas Detector, Gas Sensor, Gas Alarm
3. The SR-3000 combustible and toxic gas detector uses a catalytic sensor, electrochemical sensor or optical ionic sensor, and is an independent detector based on a highly integrated embedded industrial microprocessor.
1. Gas Dosing and Mixing System
3. The SR-S3000 gas mixing system is equipped with an online analyzer that is controlled by a micro-computer. It is used for gas distribution and injection combined with a high-precision quantitative sampling valve.
1. Industrial Gas Analysis System
3. The process gas analysis system is designed according to specific working conditions and sample gas conditions.
1. Analyzer Shelter, Analyzer House
3. An analyzer house is installed on site, and is an open air equipment piece often used in chemical factories and other process sites.
