Ensuring 24/7 Monitoring in All Conditions
Truchek provides true continuous hydrostatic monitoring of double-wall tanks in every scenario. Truchek’s successful performance of 24/7 leak detection of inner and outer tank walls, in dry-hole and wet-hole conditions – is based on 100,000+ installations. Hydrostatic monitoring avoids the limitations of passive monitoring, such as failure to signal leaking fuel in a dry hole. It also avoids expensive testing of a tank’s interstice that can be required with passive monitoring.
Meets industry tank-tightness testing requirements
Truchek meets both NFPA 329 and EPA’s criteria, and allows for two options for testing tank tightness.
- 10-hour test (tank not in use) with a 99% probability of detection and a 1% probability of false alarm – meets NFPA 329 criteria
- 4-hour test (tank in use) with a 95% probability of detection and a 5% probability of false alarm – meets EPA’s criteria

- Dual-purpose functionality – leak detection and periodic tightness testing
- 24/7 continuous tank monitoring regardless of installation conditions
- Top monitoring choice for double-wall tanks
- Tank-tightness criteria verified by the National Work Group on Leak Detection Evalutaions (NWGLDE)
