Tinker & Rasor M1 Retro Holiday Detector – Low Voltage Wet Sponge Testing

Description

The M1 Retro Holiday Detector is a low voltage, wet sponge holiday detection instrument designed for quality assurance on thin film coatings. Featuring a regulated 67.5V DC output, dual resistance settings, and a push-button calibration check, the M1 Retro provides precise and non-destructive testing of coatings up to 20 mils on conductive substrates like tanks, piping, and concrete.

Engineered for field use, this sponge-type holiday detector is housed in a rugged belt-worn case and includes a lightweight 18″ wand with sponge assembly. The unit runs on a standard 9V battery, and includes a 3.5mm headphone jack for use in noisy environments—making it ideal for inspectors who need portable, reliable, and compliant low-voltage holiday detection.

Product Benefits:

• Reliable Detection: Regulated 67.5V DC output ensures consistent testing performance
• Versatile Resistance Modes: Switch between 80Ω for metal and 90Ω for concrete coatings
• Portable & Lightweight: Belt-worn construction with ergonomic wand for ease of use
• Non-Destructive Testing: Sponge-type detection prevents coating damage
• Standards Compliant: Meets NACE SP0188, ASTM D5162-A, and other low-voltage holiday detection protocols
• Quick Calibration Check: Built-in push-button verification ensures confidence in readings
• Field Ready: Includes 25’ ground cable, 18″ wand, sponge electrode, and water wetter for immediate deployment

Typical Applications:

• Pipeline & Tank Coating Inspection: Verify continuity of thin film coatings on conductive substrates
• Concrete Surface Testing: Ideal for concrete structures treated with corrosion protection coatings
• Storage Tanks, Pipes, and Vessels: Ensure defect-free coatings in water, chemical, or fuel storage assets
