SDT340 Tank Test
The Professional’s Choice for Domestic Underground Tank Tightness Testing
Protect the environment and your clients’ assets with the SDT340 TankTest, an advanced ultrasonic system for detecting leaks in domestic underground storage tanks. Its unparalleled sensitivity allows you to find “mini defects” before they escalate into costly and damaging environmental events.
How it Works: Fast, Non-Invasive, and Accurate
The SDT340 uses a proven acoustic method to test tank tightness. By creating a partial vacuum inside the tank, it detects the distinct ultrasonic sound of air rushing in through any perforation. This non-invasive process is a game-changer for efficiency:
- No tank emptying or cleaning required. You can test a full tank, eliminating time-consuming prep work.
- No stabilization time needed. Get immediate results on-site, allowing you to move quickly from one job to the next.
- Dual-sensor technology tests both the liquid and air sections of the tank simultaneously, and you can even test the tank and piping in a single operation.
- Guided Mode ensures a quick, intuitive, and accurate test every time by walking you through each step.


Key Features & Benefits:
- Unequalled Sensitivity: Detects even the smallest leaks before they become a problem.
- Comprehensive Kit: The all-in-one kit includes everything you need for a complete inspection, from a vacuum pump to specialized acoustic sensors and a rugged protection holster.
- Verifiable Results: The included Leak Simulator proves the test was performed correctly, protecting you from claims of a poorly executed job.
- SDT TankTest Reporter Software: Create detailed, tamper-proof reports with unique numbering. The software license is free and provides unlimited use, saving you money on recurring costs.
Important Note: The SDT340 is not ATEX certified and is designed for use in non-explosive atmospheres.
