Aspen
Not RecommendedField testing showed the sensor cannot hold a reliable reading here, usually because the wounding response floods the install site and it reads zero.
Performance
Not recommended. Field trials in aspen saplings showed sensors producing sustained positive readings well above 0 bar, inconsistent with pressure chamber measurements of -15 to -30 bar. Reinstallation did not resolve the issue. Likely a species-specific xylem compatibility problem.
Known Issues
- Sustained positive readings inconsistent with pressure chamber measurements (-15 to -30 bar).
- Reinstallation does not resolve it, indicating a species-specific xylem incompatibility.
