About
The NeoSRO product line is designed for real-time pressure and
temperature measurements by using a mono-conductor e-line cable.
This model provides cost-effective solutions for oil producers to obtain
real-time downhole data.
The NeoSRO gauge sends data from downhole to surface on
real-time basis. The real-time data are displayed and saved on a surface
computer connected to a surface unit from Neotek.
MaxSRO software is provided free of charge for showing data in
both graphs and tables as well as conducting other functions. Well
depth can be up to 10,000 meters.
