VN202 MkII
The VN202 mkII has been designed as one of the next generation of diving oxygen analysers, following on from the successful VN202.
Suitable for the worldwide hostile diving environment, the VN202 mkII is easy to use with either hand and has very large digits.
It uses the proven R-17VAN oxygen sensor (as used in the VN202) with integral temperature compensation.
It is powered by two internationally available AA alkaline batteries, with an estimated life of 12-18 months.
The VN202 mkII is available in 2 versions: yellow On/Off button – automatic switch off green On/Off button – manual switch off.
The instrument is sealed for water resistance (IP65) and designed to be drop resistant.
The battery is housed in a separate compartment from the sealed electronics and can be changed without the use of a tool. Ensure batteries are fitted correctly. See internal labels.
