MODEL:OXYMON 

OXYMON Series Zirconia oxygen analyzer is an analyzer used to monitor and control the oxygen concentration of combustion gases, boilers and flue gas in industrial furnaces. It is widely used in industrial fields requiring a large amount of energy - such as steel mills, power plants, petroleum and petrochemical, ceramics, paper, food or textile industries, as well as various types of incinerators and medium/small boilers. In these areas, it can help save energy. It can also reduce the emissions of CO2, SOx and NOx by controlling complete combustion, and contribute to protecting the earth's environment, preventing global warming and air pollution.

The zirconia oxygen analyzer consists of a detection unit (oxygen probe) and a control unit (transmitter). Among them, the detection unit is installed on the flue, and the detector is composed of a dust proof device, zirconia tube, heating furnace, thermocouple, gas conduit, junction box and shell. The whole device adopts a fully enclosed structure to increase the sealing ability of the whole device and improve the service life. The control unit is the terminal for the user to operate the integrated functions, including the operation panel, the display interface, and the 4-20mA current output port. The oxygen analyzer with automatic calibration also includes a standard automatic order box.

Model: UT-IN Online Series  

UT-IN is a flameproof bypass type tunable laser gas analyzer for industrial on-line analysis and environmental on-line monitoring, especially suitable for harsh working condition such as high temperature, high humidity, high dust, and high board. The analyzer contains auto purge function with greatly reduces maintenance cost.

UT-IN laser gas analyzer consists of transmitter, received and gas cell. The transmitter drives the tunable diode to emit laser of certain wavelengths, which passes through the gas cell, then reaches the receiver. The receiver performs signal processing to obtain second harmonic signal, then calculates the concentration according to the relationship between the second harmonic signal and the gas concentration. 

Model: UT-IN-S-N-O-H-230

SO2-NO2-CO2 measurement:

• This analyzer uses UV absorption (for SO₂ and NO₂) and IR spectroscopy (for CO₂) in a compact, robust sensing head with LED light sources and no moving parts, requiring virtually zero maintenance.

Accuracy is ensured through automatic zero calibration using ambient air, with CO₂ scrubbed by a long-life disposable filter (2+ years replacement interval).

• Service needs are minimal: 36V DC power (@50 VA) and RS485 digital output via a single 4-way sealed connector.

NO/H2O Measurement:

• The NO/H₂O sensor uses the same in-situ probe design as the SO₂/NO₂/CO₂ sensor but employs a Quantum Cascade Laser (QCL) as the radiation source. The QCL provides a narrow, precise IR beam, allowing measurement of a single NO absorption line free from H₂O interference for highly accurate, noise-free readings. It simultaneously measures H₂O concentration using a nearby spectral line.

• Unlike traditional chemiluminescence (maintenance-heavy) or IR/UV methods (cross-sensitivity and short lamp life issues), the QCL offers long-term stability, no moving parts, and virtually zero maintenance, with a lifetime measured in decades.

• The analyzer measures NO from <10 ppm to several thousand ppm at temperatures up to 450 °C and can be adapted for other gases (e.g., NH₃) by selecting a suitable QCL wavelength, making it ideal for applications like SCR control in coal-fired power plants.

Model: UT-IN-S-N-O-H-230VAC

UT-IN series Flue Gas Analyzer is a highly integrated single-flange gas monitoring equipment, of which, core detection module adopts Tunable Diode Laser Absorption Spectroscopy (TDLAS), Differential Optical Absorption Spectroscopy (DOAS) gas absorption technology and Zirconia with independent intellectual property rights. The specially designed measuring cell effectively improves optical path length for gas absorption, which can measure trace gas accurately inside pipeline UT-IN series can be widely applied in online gas monitoring occasions including denitrification device, boiler flue and exhaust detection, etc. One equipment can realize online monitoring for multiple gas components, such as CO, CO2, SO2, NO, NO2, O2, H2O etc.

MODEL: OXYMON-ZPM

 It is widely used in N2 reflow furnace, N2 direct flow furnace, air separation device, gas puritymanagement, protective inert gas, ferrite sintering furnace and other environments to measureoxygen concentration

Model No: ZY-OXY-PM/PMD

The   ZY-OXY-PM   series   paramagnetic   gas   analyzer   is   based   on   the   characteristics   of   oxygen   with high paramagnetic. It can detect various concentrations of oxygen such as trace oxygen, constant oxygen and purity oxygen.  The magnetic mechanical principle has high analysis precision and long service life. It has non-explosion-proof and explosion-proof models and can be used in industrial hazard applications.

Model: UT-IN Series  

The laser gas analyzer can measure high-temperature (700°C), high-dust (50g/m3) flue gas,and can realize in-situ analysis at the work site; and the laser gas analyzer has a short response time, which is a true "real-time online" analysis instrument. It can be used to measure CO, CO2, O2, NH3, HCL, HF, CH4 and other gases. Provide real-time and accurate data for process monitoring, safety monitoring, and pollution monitoring.

Description


The Quench Water Sampler is used to take water samples from high-temperature and high-pressure lines for pH measurement. It cools the hot water sample to a safe temperature before it reaches the pH analyzer. This helps to protect the sensor and ensures accurate and reliable pH readings. The system is made of stainless steel for long life and safe operation.

Sampling System for Gas Detection Systems
Gas Detection Sampling System is designed to monitor Gas atmospheres. SEPL offers   customized sampling system based on different conditions. Standard sampling system consists of Isolation valves, blow down valves, rotameter, Air filters and the gas Detection system.

The Sample is passed through the sample system wherein we control the temperature, pressure and flow. The filtered and conditioned sample Gas is then passed across one or two different Detectors. This system is fault tolerant removing the need for expensive downtime and maintenance.

All transmitters have a 4-20 mA signal for direct connection to the site DCS, PLC or site control system. If needed we can provide local Alarms along with 4-20 mA output with a wide range of dry contacts, making the system very sophisticated and user friendly.

The Sea Water Sampling System is designed to safely collect representative seawater samples for chemical, biological, or physical analysis. It ensures accurate sampling from different depths or locations while preventing contamination. The system can handle high salinity, varying temperatures, and offshore conditions, making it ideal for marine research, environmental monitoring, and industrial applications.
