GA-12plus handheld combustion analyser
GA-12plus

Handheld combustion analyser using electrochemical sensors.

A further development from the tried and tested GA-12 hand-held combustion analyser. This new analyser is equipped with the following extra features:

  • Can be fitted with up to 4 electrochemical sensors.
  • Suitable for a soot test using electronically controlled gas volume.
  • Fitted with a powerful Li ion battery.
  • Big memory capable of storing 32 measurement reports.
  • Backlit graphic LCD
  • Robust metal connectors

An attractive alternative to other, bigger analysers. Manufactured according to the principles of EN50379.
