PORTABLE SAMPLING
HERMetic Sampler GTN for Marine Applications
The HERMetic Sampler GTN Chem is dedicated to applications where closed sampling is required, and when the sampled liquid should avoid any contact with the atmosphere in order to maintain its specifications.
What Is It?
The HERMetic Sampler GTN Chem is a portable gas tight sampler with liquid transfer under completely closed conditions into a septum-sealed laboratory bottle. It maintains sample integrity by preventing liquid contact with the atmosphere. A closed vapor recovery system dispatches vapors back into the tank. It is ideal for the following cases:
- When a representative sample of content is required
- For clean chemicals or refined products
- When samples must avoid atmospheric contact to maintain specifications
- When no gas release is permitted during sampling
- For connection on 2-inch HERMetic compact valves exclusively
The gas tight construction prevents pressure release and fume exposure, and the equipment is certified for use in potentially explosive areas. It can be fitted with specific sampling bottles for zone, spot, running, or bottom sampling.
How Does It Work?
Allows easy installation on 2-inch vapor control valves using a quick connect coupling. The sampling height can be read from a graduated tape. Liquid is transferred into a septum-sealed laboratory bottle after sampling. Carries KEMA 06ATEX0027 (II 1 Gc IIB T6) Construction Safety Approval and complies with EU Directive 94/9 EC. Approved by all major classification societies. Complies with API (MPMS Chap 17.11).
- Maximal tank overpressure: 0.3 bar, 4.4 psi
- Tape length: 30 m, 100 ft
- Capacity of sampling bottles: ~0.5 l
What Problems Does It Solve?
Ensures safety by preventing exposure to potential fire, health and air pollution hazards. Guarantees that the sample taken is never altered or contaminated by atmospheric contact. Users benefit from lower operation and maintenance costs.
