APPLICATIONS

The G 1690 is a cheap and precise diving gas measuring device, but it is also a cheap but high-quality entry-level device for many other oxygen measurements - for example inert gas measurements. 

TECHNICAL SPECIFICATIONS

Measuring ranges oxygen concentration:

G 1690-35 / G 1690T-35: 

         0.0 ... 100.0% vol. O2, recommended for 0.2 ... 35.0% vol.% O2 

         (outside reduced accuracy) 

         standard for diving gas in recreational diving, 

         Protective gases with increased CO2 content and much more.

G 1690 MAX / G 1690T MAX: 

        0.0 ... 100.0% by volume O2 

        (also for values ​​<=0.2 and over Vol.-% O2) e.g. for protective gases with 

        lowest O2 content or high-percentage oxygen mixtures 

        with low CO2 content

        Resolution 0.1 vol% O2 

G 1690T-XXX: recreational diver variant: 

MOD calculation for Nitrox up to 36% 

        0..+169 ft. MOD resolution 1 ft. 

        0..+60m MOD resolution 1m 

Accuracy with calibrated device at nominal temperature:
