Data acquisition is an important function in Continuous Emission Monitoring Systems (CEMS). The main objective of the data acquisition system is to provide real time reports that can be used for compliance reporting, process improvements and environment performance management. With in-built GSM/LAN connectivity, the gas readings are uploaded to the cloud, where they can be viewed from anywhere in the world on a laptop or mobile device and alarm functions can easily be configured, allowing 24/7 continuous monitoring.
Chemical Oxygen demand is defined as the amount of oxygen required for the oxidation of all the organic compounds present in a water sample.
The Uniphos online COD analyzer is a programmable, fully automatic analyzer which measures COD of waste / effluent water samples using a direct method of analysis. This direct method involves oxidation of sample by potassium dichromate and measurement by potentiometric titration. No human intervention is required during the measurement, as the analyzer is completely automated.
The inbuilt diagnostics feature gives an alarm if there are any faulty components or if the reagent level goes below the minimum level. Equipped with a next generation touchscreen HMI for display and programming, the analyzer provides a variety of data communication options such as RS-485 MODBUS and industry standard 4-20 mA analog output

The portable, microprocessor based Uniphos COD analyzer operates on the non-dispersive absorption principle to measure COD of waste / effluent water samples. This easy to use battery operated analyzer features an easy to use intuitive interface and has in-built data logging facility as standard. The stored data can either be exported to a computer or printed as a report to a RS-232 printer.
A COD Digester is also provided with the COD analyzer for digestion of the water sample mixed with reagents. It is a robust instrument capable of accommodating 25 vials at a time. A PID controller in the digester ensures that all the samples are heated precisely to 150oC.
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 emission of pollutants such as CO, CO2, NO, NO2, total NOx, SO2 etc. from stacks are often measured and reported for regulatory compliance purposes on a mass flow rate basis. Mass flow rates are typically calculated and reported in units of lbs or kg per hour and tons per year for these pollutants. The pollutant mass flow rate is a function of the pollutant concentration of the stack gas, the stack size & shape, and the stack gas velocity.
The Uniphos Integrated Temperature, Pressure and Flow Probe is meant for continuous and real time measurement of Temperature, Pressure and velocity of gases in industrial stacks. All the three sensors are integrated on a single flange and can easily be mounted on the stack without any hassle.
All diatomic and polyatomic molecules have one or several vibrational modes which can absorb radiation and give rise to a unique absorption spectrum in the infrared region with several absorption lines. Taking any one of the IR absorption lines of the target gas as its finger print, an instrument can be built for measurement of target gas concentration. Infrared technique is endowed with very high specificity when a right choice of the vibrational frequency of the target molecule is made. This technique is cost effective and reliable for measurement of gas concentration in parts per million range.
The Uniphos NDIR Stack Gas Analyzer are endowed with specificity and have adequate sensitivity for the detection of gases like SO2, NOx, CO, CO2 and CH4 in industrial stacks. The in-built powerful pump enables the analyzer to draw the sample from stack. Analyzer is equipped with the latest embedded and IOT technologies which enables the user to perform Remote calibration. This PLC based analyser incorporates all desired features which makes it user-friendly and fail safe.
The Uniphos Envirotrack is microprocessor based portable instrument custom made to measure the pollutants in the Ambient Air. It comes with an Air sampler where the sample air is scrubbed in a solution specific to the pollutant. The pollutant gas dissolves in the gas specific chemical and is further processed to produce a colored dye. The instrument measures the absorbance of light passed through this colored dye and relates it to the concentration of pollutants in ppb levels.
With datalogging included as standard and the presence of a USB interface, the user can easily transfer the stored data along with time and date to a computer.
The GasFinder3-OP is a field deployable Open-Path Tunable Diode Laser (OP-TDL) based gas analyzer system that is primarily used for:
This technology is also most commonly referred to as Open Path Gas Detection (OPGD) or Line of Sight (LOS).
This particular technology is ideal for detecting or monitoring for a number of different Toxic, Combustible, Hazardous, or Greenhouse Gases.
Operating on the principle of absorption spectroscopic technique to measure COD, BOD & TSS in Industrial wastewater, surface water, etc., the probe is equipped with a solenoid valve which is capable of auto purging/ cleaning the sensor. The Light source and UV detector present in the instrument provide an accurate measurement of COD, BOD, & TSS in wastewater.
Equipped with a next generation touchscreen HMI controller for display and programming the unit, the probe provides a variety of data communication options such as RS-485 MODBUS and industry standard 4-20 mA analog output. The analyser is also programmed to display BOD value of known matrix
