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.
