APPLICATIONS

The G 1690 is an inexpensive and precise diving gas meter, but is also an inexpensive but at the same time high quality entry for many other oxygen measurements - for example for protective gas measurements. 

 

TECHNICAL DATA

Measuring ranges oxygen concentration:

 

G 1690-35 / G 1690T-35: 

         0,0 ... 100.0 % vol. O2, recommended for 0.2 ...   35.0 % vol.-% O2 

         (reduced accuracy beyond) 

         Standard for diving gas , 

         Protective gases with increased CO2 levels etc.

 

G 1690-MAX / G 1690T-MAX: 

        0,0 ... 100.0 vol% O2 

        (also for values <=0.2 and above vol.-% O2) e.g. for inert gases with 

        lowest O2 content or high-percentage oxygen mixtures 

        with low CO2 content

        

        resolution 0.1 vol.-% O2 

 

G 1690T-XXX: Sport diver version: 

MOD calculation for Nitrox up to 36%. 

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

        0..+60 m MOD resolution 1 m 

 

Accuracy with calibrated instrument at nominal temperature:

Variants G 1690_-35: Sensor GOEL 370

< 2 vol.-% O2: +/-0.2%

< 35 Vol.-% O2: +/- 0,5%, above not specified

Variants G 1690_-MAX: Sensor GOEL 381 

< 2 Vol.-% O2: +/-0.1% 

< 35 Vol.-% O2: +/- 0.5% 

< 100 Vol.-% O2: +/- 1.5%
