Divesoft Nitrox Analyser (DNA)

An ideal tool for every Nitrox diver. An innovative, accurate, durable and user-friendly Nitrox Analyzer that fits in your pocket and connects to your smartphone via Bluetooth.

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.

NOTE: The Oxygen sensor is sold separately.

The DNA does not include the Oxygen sensor. The Oxygen sensor is purchased separately as the DNA can be used with a functional spent rebreather oxygen sensor R22 (Molex connection) which is easily replaceable by the user. Help the environment by recycling your buddy’s rebreather Oxygen sensor during their annual sensor replacement.

Package includes:

#8460 DNA (without the Oxygen sensor)
#3864 Semi-hard zipper case 75×150
