Holiday Detection

Tinker & Rasor “M-1 Low Voltage” Holiday Detector

The M-1 is now worldwide as the best choice for the inspection of thin film coatings (0-20mils). The totally redesigned M-1 now uses 6 AA batteries and an advanced circuitry to produce 67.5 Volts. With on-board calibration verification, the M-1 can be checked in the field with no other test apparatus needed. An L.E.D. lights on the front panel when the unit is in calibration and a holiday is detected. The M-1 comes complete ready to work right out of the box. Head phones may now be used in noisy environments that drawn out the normal audio sound.
