Truchek® provides two benefits: continuous monitoring and tank-tightness testing

Truchek® provides a simple, reliable method for continuous hydrostatic monitoring of the tank interstice in both dry-hole and wet-hole conditions. In addition to monitoring both tank walls, Truchek provides options for tank-tightness testing.

Truchek avoids the limitations of passive-monitoring option using a liquid sensing prove in a dry insterstice. Regulations often require continuous monitoring of a double-wall tank or expensive periodic testing of the interstice. Truchek meet both requirements – hydrostatic monitoring and interstitial testing. Visit our new tank installation videos.
