NM01HHDKIT

Detects holidays, porosity, pinholes, leaks, and other discontinuities in coatings, linings, and membranes using pulse or continuous DC

• Available as a stick-type with pulsed DC or a compact wand style with continuous DC
• Lightweight, ergonomic design provides comfortable all-day use, reducing operator fatigue
• Regulated pulse or continuous DC voltage output that won't change under load— ±5% voltage accuracy
• Voltage calculator feature—input the coating thickness to automatically calculate the required test voltage
• Extensive electrode options—choose from a wide range of rolling spring and flat wire brush electrodes or use electrodes from other manufacturers with optional adaptors—custom sizes available upon request
• Long Form Certificate of Calibration included with each instrument

• Easy-to-use with bright, color LCD
• Ready to measure—includes everything needed for testing
• Audibly and visibly alerts when flaws/holidays are detected
• Lightweight, ergonomic design provides comfortable all-day use, reducing fatigue
• Voltage calculator feature—input the coating thickness to automatically calculate the required test voltage
• Press-and-hold Safety Trigger helps prevent accidental high voltage generation
• 7.6 m (25') ground (earth) cable with locking connector and spring clamp
• Shock proof/creep proof—internally sealed to minimize creep distance to high voltage components. Designed in accordance with IEC 61010-1.
• Built-in certified voltmeter (crest meter, jeep meter) displays and regulates the voltage at the electrode
• Long Form Certificate of Calibration included with each instrument
• Conforms to national and international standards including ISO, ASTM, and NACE
• Strobe light and loud audible alarms emitted when a holiday is detected.
• Loud audio alarm remains audible in noisy environments
• Removable Smart lithium-ion battery
