| Maintenance | Cleaning sensor, replacing o-rings | Cleaning sensor, replacing o-rings, checking vent tube (blow out fitting), no desiccants to replace |
| Applications |
- deeper applications, higher fluctuations - when barometric data is required (barometric efficiency) - very humid conditions, risk of wellhead flooding - areas prone to long-term freezing conditions - hard to reach areas, cumbersome deployment |
- shallow applications, low fluctuations - surface water, wetlands - watershed monitoring - stormwater and flood monitoring - no option for Barologger deployment, or don't want extra step of data compensation |
