AGMS Extractive Analyzers

Overview

Anodyne CEMS is an online analyser for measuring concentration of various toxic gases in industrial process/ boiler stack. Being capable of Auto /remote calibration with digital communication, it provides a complete solution for stack monitoring. Anodyne CEMS analyzers are available spectrum of technologies depending on suitability, type of stack and user requirements. The technologies offered are mainly listed as:

  • Highly Sensitive and specific Chemiluminiscence based NOx analyzers
  • Highly Sensitive and specific UV Fluorescence based SO2 analyzers
  • Highly specific and sensitive Zirconia based Oxygen Analyzers
  • Non-Dispersive Infrared (NDIR) based Analyzers
  • Tunable Diode Laser Absorption Spectroscopy (TDLAS) based Analyzers
  • Ultraviolet Differential Absorption Spectroscopy (UV DOAS) based analyzers
  • Electrochemical sensor based Analyzer (discontinued)
  • Partnered with Uniphos Envirotronic Pvt. Ltd., a UPL group company and largest manufacturer of Gas Sensors in India, we offer a range of Gas Analyzers. All our scientific testing instruments are designed and developed by our of specialist engineers.

Features

Anodyne CEMS analyzers are equipped with range of features for ease of operation and cost efficacy. The main features are highlighted as below:

All analyzers are based on PLC and microcontroller catering to a rugged and reliable analysis of gases.

All AGMS CEMS are equipped with a sample pre-conditioning and conditioning systems that comprise of sampling probe, Sintered dust filters, sampling tube, micro filters. In-built pump is provided for sampling of gases and maintains constant pressure in the analyzer.

In – built zero air generation for zeroing and purging

AGMS state of art the technology to remove moisture and hydrocarbon scrubbing system caters to specific gas analysis.

All analyzers come with standard connection to AirQWeb, patented software from Turnkey which connects all instruments and generate graphs, time stamped excel and pdf logs.

User Friendly Interface

The colour touch screen and intuitive interface available makes very easy to test or configure the Analyzer. The interface allows offers features like measuring, zeroing, calibration, service and more. A USB port is provided to download the last 24hours recorded measurements as well as a diagnostic file containing the configuration and useful information for remote troubleshooting. The software of the controller can also be upgraded by connecting a USB key. An RS232/485 port supports MODBUS protocol to transmit each measuring channel value to a Data Acquisation System and can be connected a SCADA system. Additional parameters like status code, error code, calibration values, are available as Standard protocols in Diagnostics.

Remote Calibration

AGMS range of analyzers are designed to sustain every process/ stack condition and follow complete Government regulatory standards and design requirements. Each analyzer is equipped with Auto / Remote calibration system. The gas analyzers come with electronically controlled solenoid valves which function automatically. The valves are connected to gas cylinders which are controlled by remote calibration hardware and software. After every reading and calibration an automatic zero is performed.

Multiplexing System

When different stacks need to be analysed, AGMS analyzers come with an optional model which caters to monitoring upto 3 stacks with single analyzer. This feature is cost effective as only different sampling probes and sampling tubing is required for each stack with single analyzer stationed in a central control room.

Automatic Cleaning/Purging

AGMS analyzers are equipped with automatic and time controlled purging system. The intuitive analyzer interface and in – built pump drives a solenoid valve on compressed air to clean the probe and entire sampling line. It can alternately drive an air compressor if no air network is available on site. The period and cleaning time are adjustable to adapt to different applications and is selected and advised as per suspended particulate values.
