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 adjusted to ambient air, constant conditions for the

measurement, sufficient measuring time:

 

Variants G 1690(T)-35: Sensor GOEL 370

    < 35 vol.-% _O2:          -0,2 ... +0.35 Vol.-% 0₂

    35..100 Vol.-%O₂: n/a

     Sensor lifetime at 20.9 Vol.-% O₂ approx. 2 years

 

Variants G 1690(T)-MAX: Sensor GOEL 381

35 vol.-% O₂:                  ‡0.25 vol.-% O₂:

35...100 Vol.-%O₂:          ‡2% *(measured value-20.9 Vol.-%O₂).

Sensor lifetime at 20.9 vol.-% On > 3 years
