NeSS®: Sampling devices for Tanks & Vessels
MAIN FEATURES:
The NeSS® is a sampling device fixed on tank or vessel wall
Its design makes it possible to take a safe liquid sample, thanks to “Dead Man Hand Wheel Design” and by limiting fugitive emissions during the operation. The fugitive emission gases are captured through the replaceable gas cartridge screwed onto the unit.
This system is patented (cartridges are a standard used in masks commonly used in the oil industry).
RECOMMENDATION OF ASSEMBLY
- COMPLIANCE with CODRES (French Regulation)
- AVOIDING MOUNTING ON THE ROOF OF TANK
- ECONOMIC SOLUTION
- REPRESENTATIVE SAMPLES (limited dead zone)
