Uniphos 500 HA12 Multichannel Controller with HMI

The TDLAS (Tunable Diode Laser Absorption Spectroscopy) technique in combination with WMS (wavelength modulation spectroscopy) is highly sensitive and specific method for detection of gases and is an excellent technique for concentration measurement of gaseous species in scientific as well as industrial applications. Uniphos TDLAS based gas analyzer are exceptionally reliable for trace level detection of atmospheric pollutants like HF, HCl, NH₃ etc. Our TDLAS based analyser provides an accurate and real time measurements of these atmospheric pollutants from ppm levels to percentage levels.   

The Uniphos Simple Sampling probe is tailor made for situations where temperature of the stack is not high, and condensation does not happen while extracting the sample from the stack. The dust filter present in the probe ensures that no dust is passed through the line.  User-Settable purging facility enables automatic purging of the probe at pre-defined time intervals.  

The Uniphos Peltier Cooled Probe is an advanced sample conditioning system to draw a gas sample from an emissions stack being monitored. Sample extraction and conditioning is an important part of all Continuous Emission Monitoring Systems (CEMS) and includes extracting the sample from the stack and maintaining the dew point of the sample at such a level that there is no condensation at any point until the concentration of the sample is measured. This ensures proper transport and measurement of sample concentrations.  

The Peltier Cooled Probe is a unique product which is based on an advanced hot and dry extractive technique where the sample is extracted and conditioned on the stack and transported to the analyzer using a non-heated sampling tube at ambient temperature. It consists of a stack mountable system which includes a heated probe, a short, heated sampling line and a Peltier cooled sample conditioning module, all integrated in a single enclosure. Using a Peltier Cooled Probe reduces the length of the heated sampling line to less than half a meter, bringing down the operating cost many times. 

The Uniphos Fluorescence Based SO₂ Stack Gas Analyzer is a reliable instrument with high sensitivity and selectivity which is designed and developed to meet customer’s requirement for measuring the concentration of SO₂ in PPM levels. Specific optical filters in the fluorescence cell in addition to moisture and hydrocarbon scrubbing systems ensures removal of any interferences making the analyzer highly specific for SO₂ detection.  

The optical excitation of SO₂ molecules results in fluorescence in the wavelength region typically between 240-420 nm and the fluorescence intensity is related to SO₂ concentration.  

The Analyzer is equipped with the latest embedded and IOT technologies which enables the user to perform Auto/ Remote calibration. The analyzer comes with built in diagnostics and internal memory which can store the test results along with date and time.
