Zetian - Ultrasonic Flue Gas Flowmeter

FLW-300 single-ended flue gas ultrasonic flowmeter is a device for measuring gas flow rate based on the principle of ultrasonic transit time. The product adopts the innovative structural design of integrated temperature and pressure flow, which is easy to install and disassemble, and meets the requirements of relevant national standards. It is used for the flow rate measurement of boiler flue, chimney flue gas, etc. s Real-time continuous measurement of flue gas temperature, pressure, flow velocity and flow rate of low-speed flue, flue that cannot increase openings, etc.

Zetian - Dynamic Diluter

The DC-200 Dynamic Diluter uses high-precision mass flow controllers (MFC) to accurately controls the flows of dilution gas and standard gas so as to get standard gas of required concentrations. The standard gas path is made of passivated stainless steel tubes and is heated throughout to reduce the impact of sample residues on dilution accuracy. The product is mainly used in plant boundaries, ambient air on-line monitoring systems and preparation of standard gas in laboratories, with the advantages of high accuracy of gas proportioning, fast response time, high reliability and easy operation

Zetian - Ultrasonic Doppler Flow Meter

Based on the Doppler effect, the ZDMFA-01 Ultrasonic Doppler Flow Meter can simultaneously monitor the flow rate, velocity, water level, water temperature and other parameters with millimeter-level accuracy, suitable for fluid flow measurement in a variety of environments. In a one-package structure, the product is easy to operate, waterproof and pressure resistant, not affected by external environments and has a low failure rate. Therefore, the product meets the user's requirements for high accuracy and high stability.

Zetian - Enrichment Desorber

The Enrichment Desorber is a pretreatment device for gas chromatography analyzers. It is a fully automated, direct-feed, single-channel cold trap enrichment and thermal desorber that uses a combination of six-way valves and solenoid valves in the gas line design, and Tenax or activated charcoal adsorbent tubes as the enrichment and thermal desorption tubes to enrich trace volatile organic compounds (VOCs) in the ambient air, thus lowering detection limits of chromatography analyzers.

Zetian - Intrinsically Safe PID Detector

The PID Detector can effectively measure volatile organic compounds (VOCs) and other toxic gases. When organic gas is fed into the PID detector, an ultraviolet (UV) light source is used to open the chemical bonds of the organic gas, releasing free ions and electrons. The detector measures the charge of the ionized gas and converts it into a current signal, which is amplified to display the content of the organic gas via the data acquisition module.

Zetian - Explosion-Proof FID Detector

The Explosion-Proof FID Detector consists of an explosion-proof cavity, mounting base of flame arrester element, signal transmission line, control wire of temperature transmission and ignition heating wires, etc. When the organic gas is fed into the FID detector, the chemical bonds of the organic gas are opened under the action of high temperature ionization, releasing free ions and electrons. The released electrons move toward the electrode at one end of the high-voltage electric field, and thus are collected by the electrode to produce a measurement current. The magnitude of this measured current is related to the mass of organic gas entering the detector per unit time, and the total amount of signal collected during the injection time reflects the content of the organic gas.

Zetian - UV-DOAS Module

It is mainly used to measure harmful gas components in pollutant discharge pipe, widely applied in environment monitoring and thermal parameter measurement. The module can measure harmful gas concentration, including SO2, NO and NO2, etc. Compared with instruments adopt electrochemical sensor for measurement, it has advantages of high accuracy& reliability, fast response and long service life. Employing innovative anti-jamming algorithm, advanced material and sensor, the module is with stable performance and reliable quality.

Zetian - Portable Flue Gas Analyzer (Cold-dry)

EM-5P Portable UV Flue Gas Analyzer is mainly composed by monitoring unit of gaseous pollutants (SO2, NOX, CO, CO2), monitoring unit of flue gas parameters (e.g. oxygen content), data collection & processing unit. The structure consists of flue gas sampler, transmission pipeline, flue gas pre-processor and analyzer. The product is equipped with Android touch screen, large storage capacity, multi-port output and printer for real-time monitoring data, etc.

Emissions Monitoring - Flue Gas Analyzer

Zetian - NOX Converter

The NOX-200A is a pretreatment device for NOx analyzers developed by our company for ambient air quality monitoring and dilution method measurement in continuous emission monitoring systems (CEMS). The converter can almost completely convert NO2 in flue gas to NO based on the technical principle of catalytic conversion combined with temperature control technology.

Zetian - Flue Gas Analyzer (Hot-Wet)

EM-5 Flue Gas Analyzer (hot-wet) is a gas analysis product of multi-return optical path on basis of years of accumulated ultraviolet absorption spectroscopy. Based on Ultraviolet Differential Optical Absorption Spectroscopy (UV-DOAS) and Stoichiometric Algorithm (PLS), the analyzer can measure SO2, NO, NO2, O2, NH3, CO, CO2, Cl2, O3, H2S,HCl, CH3I, CH2O, etc. In addition, our analyzer can configure with self-developed built-in infrared module to measure CO according to customer requirement, which has higher accuracy and reliability, faster response compared to electrochemistry method solves problem of short service life.
