PORTABLE GAS ANALYSERS
|
|||||||||||||
|
Portable flue gas analysers. From lightweight, low-cost units for O2 and CO up to top-of-the-range industrial equipment fitted with up to 9 gas sensors. Our analysers use a mixture of electrochemical and IR sensors. Of course, even the smallest analyser calculates all the relevant combustion parameters.

GA-21plus - Combustion Gas Analyser
|
|
|||||||||||
|
The portable combustion gas analyser GA-21plus is specially for service technicians who are permanently occupied with adjustments and measurements on a range of heating equipment. The added comfort of the internal printer makes this instrument a very attractive proposition. A special graphic display was developed solely for this purpose, showing oxygen against Lambda and CO as a bar chart. The instrument can also be fitted with an optional NO sensor to allow measurement of NOx concentrations, as well as other sensors for toxic gases.

GA-21Bio plus - Landfill Gas Analyser
|
|||||||||||||
 |
|
||||||||||||
|
Modern technology has at last produced an instrument that can be used both for measurement of landfill gases and testing of flue gas on heating plants. Our precision NDIR gas sensors are used for the determination of CO2 and CH4 in this landfill analyser. Further sensors can be added fro measurement of H2S or other components.
Two extra analogue inputs allow the simultaneous measurement of a voltage or current signal and a temperature. |

GA-40plus - Gas Analyser
|
|
|||||||||||
|
A further development of the GA-21plus. Can be fitted with up to 9 gas sensors and is equipped with a range of additional analogue input channels.
Using the optional dryer, it is possible to carry out longer term measurements. The analyser can also be fitted with two NDIR sensors for direct measurement of CO2 and CH4. |

GA-40Tplus - Flue Gas Analyser
|
|
|||||||||||
|
The flagship of the madur electrochemical line. Using up to 9 gas sensors and equipped with a professional sample preparation and conditioning system including heated hose and filter.
6 additional analogue inputs for voltage/current signals and temperature together with 2 optional analogue outputs give the instrument an unheard of flexibility. The analyser can also be fitted with two NDIR sensors for direct measurement of CO2 and CH4. |

Photon - NDIR Gas Analyser
|
|
|||||||||||
|
Madur's new Photon is a flue gas analyser designed to use principally infrared sensors, but can also be fitted with up to 9 electrochemical sensors. The modular construction allows the instrument to be configured to suit practically any user needs.
The range of each sensor can be chosen as required for the measuring system (within the capabilities of the sensor). The analyser also has a sufficient number of analogue and digital inputs and outputs to ensure ease of data transfer in both directions and documentation of all results. This NDIR analyser can also be used for various control operations. Equipped with advanced temperature control technology to ensure accurate and repeatable results under all conditions. |
