DNA + O2 sensor <EAN 50
Limited stock of DNA analyzers, including the R-22S Sensor, ideal for <EAN 50.
This particular R-22S sensor delivers the highest accuracy when measuring oxygen concentrations below 50%, due to its slightly higher linearity characteristics.
Important: This product is not available in the United States.
The DNA is a small & smart pocket Nitrox analyzer that offers simple Oxygen measurement. The perfect partner for recreational and beginner Nitrox divers. Analyzing is easy and comfortable using the Divesoft App. No Internet is needed as the App operates offline.
This Limited Edition comes with an Oxygen sensor R-22S <EAN 50.
The R22S sensors meet the supplier's specifications with a "linearity" value of 2-3% over the full range of 0-100% O2.
Due to the slightly higher "linearity" value, the 100% Oxygen values can be analysed, but the sensors are the most accurate when used to measure values <50% of Oxygen.
Important: This product is not available in the United States.
Package includes:
#8460 DNA (without the Oxygen sensor)
#4115 Oxygen Sensor R-22S <EAN 50
#3864 Semi-hard zipper case 75×150
We recommend:
#8009 Connecting hose
#1052 Flow limiter for QD connection
#8437 Professional flow limiter Mk2

Divesoft.app
Get all you need for your dive in one place.
The Divesoft.app was designed to be your hub to get prepared for your dive. It can be used by all levels of divers who can benefit from its features at any time.
Dimensions of the analyzer: 45.6 × 111 × 40 mm (1.8 × 4.4 × 1.6 inches)
Weight: 100 g (3.5 oz)
Weight with sensor: 126 g (4.4 oz)
Range of measuring the concentration of oxygen: 0 to 100 %
Measuring temperature: 0 to +40° C (32 – 104° F)
Mixture pressure: consistent with ambient pressure, in the range of 700–1100 millibars (20–32 inches of Hg) which corresponds to the standard atmosphere at an elevation in the range of 0 to 3000 m (0–10000 feet) above sea level.
Rated gas throughput: 0.2 L/min
Oxygen sensor: Divesoft R-22S or compatible (the expected lifetime of a brand-new sensor is 2-3 years)
Power source: CR 2450, user replaceable (the expected lifetime is 1-2 years)
The gas connection: direct contact connection to both "DIN" valve (EN 144-2) for 200/300 bars (G 5/8 thread) and M26x2 valves. Possible connection with the Divesoft professional flow limiter and connection hose.
Warranty: 24 months, 12 months on the oxygen sensor. The battery is not covered by the warranty.
