Tinker & Rasor M1-AC Holiday Detector – In-Plant Low Voltage Testing System

Description

Product Description:

The Tinker & Rasor M1-AC Holiday Detector is a precision-engineered, low-voltage “wet sponge” holiday detection system designed specifically for in-plant, continuous-duty operations. Powered by 115/230V AC, this system delivers a regulated 67.5V DC output without the need for batteries—ideal for around-the-clock production environments like rebar coating lines and high-throughput coating plants.

With dual resistance settings (80kΩ for metal, 90kΩ for concrete), the M1-AC ensures accurate, non-destructive testing of coatings up to 20 mils on conductive substrates. Built into a durable mil-spec case, the unit supports long-term use in rugged industrial environments and includes a push-button calibration check for on-site verification.

An optional external signal plug is available to integrate visual or audible alarms, making the M1-AC Holiday Detector a reliable solution for quality control and compliance with NACE SP0188, ASTM D5162-A, and other international low-voltage inspection standards.

Product Benefits:

• Continuous Operation: 24/7 testing with AC power—no battery swaps required
