MK-770-CE

Energy Saving & Preventive Maintenance

The JFE MK-770-CE is a specialized, portable Gas Leak & Discharge Viewer used for industrial maintenance and safety applications.

Gas and Air Leak Detection
The device uses an array of ultrasonic sensors to detect the high-frequency sounds produced by escaping gas or compressed air (such as air, vapor, nitrogen, argon). It then superimposes a sound pressure map onto a visible camera image in real-time, allowing the operator to instantly pinpoint the exact location of the leak from a safe distance (up to 10-20 meters).

• Air/Gas leak from:
  ・Piping pinholes and regulator joints due to corrosion

  ・Loose flange, deteriorated packing, defective welding

  ・Suction in vacuuming system

  Partial Discharge at:
  ・High-voltage transmission and transformer for substations and electrical rooms

  ・Switchboard, Insulator, Equipment terminal, Disconnector switch,
  Cable terminal, Joint section, etc

• Visualizes Leaks: Displays the leak location as a sound pressure map on a screen.
• Works in Noisy Environments: The ultrasonic sensors are not affected by audible background noise, making it effective for use in busy factories.
• Quantifies Losses: It can estimate the amount of leakage and calculate the annual loss costs, helping prioritize maintenance efforts.
• User-Friendly: An automatic mode simplifies operation for maintenance personnel without specialized training.
