GA-12 Hand-held Gas Analyser
Brand: madurGA-12 is madur’s smallest gas analyzer - hand-held, equipped with up to 3 EC cells. Small dimensions and light weight makes it very convenient for technicians that use analyzer on a daily basis.
Rich offer of equipment and add-ons makes it interesting for more demanding users. Manufactured according to the principles of EN50379.
Features- Equipped with 2 or 3 electrochemical cells (typical configuration: O₂, CO, NO/NOₓ)
- Works with an external portable printer via wireless communication (IR LED)
- Up to 60 hours of work (version with replaceable alkaline batteries)
- Fixed probe of two different lengths with inline filter and condensate trap
- Differential pressure sensor - for measurements of chimney draft and flow velocity (with help of Pitot tube)
- Additional gas filter with condensate trap (installed in the lid)
- Cooperation with digital RH and temperature sensors
- Measurements of gas and ambient temperatures
- Results presented on LCD display (128 x 64) with backlight
- Calculations of many additional parameters
- Firmware for gas calibration
- Two versions of power supply are possible:
- Version with four replaceable AA batteries (alkaline, Ni-Cd or Ni-MH)
- Version with built-in Li-ion rechargeable battery and additional mains adapter for battery charging
