Gas Leak & Discharge Viewer MK-770A

Model: MK-770A-CE / MK-770A-CCC

The JFE Tech Gas Leak & Discharge Viewer MK-770A Advanced Model: Detects Air/Gas Leaks and Partial Discharge, delivering superior energy savings & safety. The MK-770A is the advanced model of JFE Advantech's "Gas Leak Viewer" series, designed for real-time acoustic imaging of gas leaks and partial discharge from a safe distance.

MK-770A calculates and displays the annual financial loss caused by air leakage using the input values: unit price, operating hours of the equipment, and distance to the target.

Acoustic Imaging: Uses ultrasonic sensors (40 kHz center frequency) to detect leaks and overlays a "Sound Pressure Map" onto live camera images.
Dual Detection: Capable of detecting both gas/air leaks and partial discharge.
Financial Loss Assessment: Calculates annual loss costs based on unit price, equipment operating hours, and distance to the leak.
Noise Optimization: Uses an upgraded algorithm to identify and eliminate background noise for more accurate detection.
Video Recording: Unlike standard models, it can record video with a sound pressure map overlay (MP4 format).

Applications

The device is compatible with various gases, including argon, hydrogen, nitrogen, and steam. It is commonly used for:

Identifying leaks in air tubes, flanges, gaskets, and welded sections.
Detecting suction in vacuum piping.
Safety inspections for electrical partial discharge.

Detects a center frequency of 40kHz Detects ultrasonic waves with a center frequency of 40kHz, a frequency range that is most sensitive for air leak detection. *In ultrasonic leak testing under international standards such as ISO and ASTM (US), a frequency of 40kHz is commonly used. Specification : JFE Tech Gas Leak & Discharge Viewer MK-770A-CE Detection Method: Ultrasonic array sensor (calculates sound arrival time differences) Center Frequency: 40 kHz Leak Performance: Detects a 0.2 mm hole at 7 meters distance (at 70 kPa pressure) Partial Discharge: Detects 1000 pC equivalent discharge at 3 meters Detection Area: 62° Horizontal / 35° Vertical Display: 4.3-inch LCD (800 x 480 pixels) Frame Rate: High: ~8 times/sec; Eco: ~5 times/sec

Advanced Analysis :

Partial Discharge Mode: Displays a Time Waveform, Frequency Spectrum (FFT Graph), and Discharge Component Ratio to identify specific insulation failures.
Loss Cost Estimation: Calculates estimated annual financial losses based on user-input values for unit price and equipment operating hours.
Noise Filtering: Uses updated algorithms to eliminate background noise "flickering" in noisy industrial environments.
