GA-60

GA-60 portable gas analyzer

The largest of madur’s analysers equipped with electrochemical cells.
It can fit even up to 7 EC cells and up to 3 NDIR sensors.
GA-60 has a large (320x240), graphical LCD with backlighting. Datalogger with SD card for storing results and built-in ribbon printer for standard (non-thermal) paper.

Analyser is offered in two versions:

  1. In basic configuration analyser is not equipped with the gas dryer and works with the probe holder + gas probe pipe. It can be paired with PGD-100 gas dryer with heated hose.
  2. Analyser equipped with a built-in NAFION® type gas dryer and heated hose - configuration especially recommended for measurement of gases highly reactive with water or disturbed by its presence (SO2, HCl, NO2, Cl2).

Hereby tool helps to configure, in few simple steps, ready to measure analyser. It allows to select main structural components, like gas dryer, gas sensors, etc. Some elements, like probe pipes are to be selected separately. This mini-configurator, generates a list of madur codes that identifies the selected configuration. Customer may add own comments and requests. Device configuration has to be verified by pressing the Refresh button in the Order Summary section. Order summary can be send to our sale engineers for validation and in order to obtain price offer.

supplemental equipment - ordered separately, but essential to work with the analyser

Probe holder

Probe holder

THIS ELEMENT IS ORDERED SEPARATELY, YET IT IS ESSENTIAL TO WORK WITH ANALYSER!
SUITABLE ONLY FOR THE A VERSION OF GA-60 (without built-in dryer).
Together with an exchangeable gas probe pipe is a complete gas probe for extraction of gas samples.
It has single gas tube ended with quick coupler and electric cable ended with a 7-pin connector.
Gas probe pipe is mounted with a M30x1 fastening.
In the electric connector there is a PT500 sensor for measurement of ambient temperature.
Probe holder can be equipped with an in-line filter with a condensation trap (pore size of the filter inlet is 20µm).
Probe holder is available in two versions:

  1. heated (with a slit for a filter for soot measurement test)
  2. unheated (without a possibility to perform soot test)

see probe holders section

Heated hose

Heated hose

THIS ELEMENT IS ORDERED SEPARATELY, YET IT IS ESSENTIAL TO WORK WITH ANALYSER!
SUITABLE ONLY FOR THE B VERSION OF GA-60 (with built-in nafion dryer). Replaces the probe holder.
Heated hose with heated gas filter supplies gas sample to the analyser’s conditioning module.
Hose has M30x1 threaded connection to fix gas probe pipe. The other end has magnetic quick-coupler and electric connector to connect it with analyser.
Standard length of hose is 3m, it is possible to order other lengths of hoses.
Hose is provided with a carrying bag.

see heated hoses section

Gas probe pipe

Gas probe pipe

THIS ELEMENT IS ORDERED SEPARATELY, YET IT IS ESSENTIAL TO WORK WITH ANALYSER!
Exchangeable gas probe pipe mounted on the probe holder with M30x1 fastening.
It has thermocouple type K (in some configurations type S) for measurement of gas temperature and a threaded fixing cone. With the probe holder is a complete gas probe.
There are many probe pipes available. They differ in length and working temperature.
For work efficiency it is advised to own different probe pipes to be able to adjust to the measurement place.

Ordering code:
see gas probes section

Optional equipment

Ambient temperature sensor

Ambient temperature sensor

This ambient temperature sensor on a 3m cable is used for measurement of the boiler’s inlet air.
In basic configuration the ambient temperature is measured by sensor installed in the connector of the gas probe handle.

Ordering code:
Z40P-SENS-TEMP

Pitot tube

Pitot tube

Pitot tube is used for indirect measurement of gas flow velocity (measurement with the analayser’s differential pressure sensor).
A few lengths of tubes are available. Pitot tube has 2m gas tubings to connect it with the analyser.

Ordering codes:
Z00-PITOT-5002
Z00-PITOT-8002

RS232C to USB converter

RS232C to USB converter

2.5m cable that allows to connect the analyser (its RS232C port) with USB port in PC computer (especially valuable when PC is not equipped with COM port).

Ordering code:
Z40P-USB-ADAP

Bluetooth communication module

Bluetooth communication module

Module connected to the analyser’s RS232C port, allows to communicate with PC computer over Bluetooth protocol.
