gas-lab Q1
Analizzatore della composizione del gas senza combustione, che lavora in base all’ assorbimento degli infrarossi e alla conduttività del calore. Si compone in due parti: un’ involucro robusto che include i due sensori, e l’ elettronica primaria di misura. Opzionalmente può essere installato in ambiente pericoloso.
