The Multi-Sensor Water Leak Detection Probe from Electro Scan combines low-voltage conductivity technology with a high-definition CCTV camera, pressure sensor, and acoustic hydrophone, to accurately measure location, size, and gpm of each water leak. It finds water losses in pressurized water mains by measuring variations of electric current flowing through cracks, pinholes, defective joints, and defective service connections, in accordance with ASTM F2550. Available exclusively as a professional service from the company, Electro Scan Services is able to find and measure leaks that may not be detected or correctly measured by other techniques. 916/779-0660; www.electroscan.com.
