GA-60 Portable Gas Analyser
Brand: madurThe largest of madur’s analyzers equipped with electrochemical cells. It can fit even up to 7 EC cells and up to 3 NDIR sensors. GA-60 has a large (320 x 240), graphical LCD with backlighting. Datalogger with SD card for storing results and built-in ribbon printer for standard (non-thermal) paper. The GA-60 analyzer is offered in two versions:
- In basic configuration the analyzer 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.
- Analyzer 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).
- Equipped with up to 7 electrochemical cells
- Equipped with up to 3 NDIR sensors
- Built-in 58 mm ribbon, graphic printer
- Built-in rechargeable battery for up to 16 hours of operation (for basic configuration with probe holder + probe pipe)
- Measurements of gas and ambient temperatures, optionally 8 additional inputs for temperature sensors
- Additional gas filter with condensate trap (installed in the lid)
- Differential pressure sensor - for measurements of chimney draft and flow velocity (with help of Pitot tube)
- Soot measurement programme
- Analog outputs (4-20 mA / 0-10 V) - optional
- SD card data-logger for saving results
- Calculations of many additional parameters
- Firmware for gas calibrations
