Main features:
 
1. CH4 concentration in water can be measured independently;
 
2. It can be applied to ROV, anchor system observation, seabed observation network, submarine beacon, navigation observation and laboratory measurement;
 
3. Adopt rapid membrane osmotic equilibrium measurement technology, build-in non-dispersive infrared detector, and do not need chemical reagents;
 
4. There is no need to use expensive calibration gas;
 
5. It is not affected by biological attachment and has low maintenance cost;
 
6. MicroSD memory card with built-in capacity of 2G can be used for self-contained long-term observation and storage;
 
7. Low power consumption, suitable for underwater long-term measurement;
 
8. Start working immediately after power supply, and do not need to use computer control on site;
 
9. Menu control interface, simple and convenient operation;
 
10. Provide the original measurement data and CH4 concentration data in ppm units;
 
11. The instrument simultaneously measures TDGP parameters of total dissolved gas pressure.
