Model 780, 785, 670, Stick:

Model 780:

For thin film coatings the easy-carry and easy to handle SPY Model 780 speeds inspection time with its built in Jeep meter and various other time saving and comfort features. This ergonomic holiday detector incorporates all the features of the previously manufactured SPY Model 715 detector with numerous upgrades and enhancements.

Model 785:

For thicker coatings such as coal tars, extruded and tape coatings, the Model 785 has a range of infinite voltage settings from 1,000 to 15,000 volts. This wide range permits you to maintain a steady inspection rate on most types of coatings on most pipe sizes without changing detectors. Pulse voltage output only.

Model 670:

The Model 670 is lightweight and easy to handle. The electrode wand assembly is easily inserted into the unit and secured. Since the working voltage is quite low, a direct connection from the ground cable to the conductive metal under the coating must be made. A trailing ground wire will not suffice.
Inspect more area faster. A revolutionary roller sponge electrode is an optional accessory for the Model 670. With this roller sponge electrode, coating inspections move along faster and with less operator fatigue.
The Model 670 operates on a single 9 volt alkaline battery housed in the detector handle. These standard batteries are readily available at retail stores. Under normal conditions, the battery will have a long life. There is a minimal drain on the battery until a holiday is discovered. Unit output is 67 volts DC. This voltage makes this detector sensitive and accurate. A uniform coating of only one mil of paint or other non-conductive material is sufficient to repel this small current. If a pin-hole holiday is encountered, moisture from the sponge will seep in to create a free path for electrical flow, activating the signal horn.
For coatings from 1 mil up to 10 mils thick, ordinary tap water can be used to wet the sponge. Above 10 mils, for coatings of 11 to 20 mils thickness, a non-sudsing wetting agent (such as Kodak Photo-flow) is recommended to increase the ability of the moisture to swiftly make its way through pin-holes in the thicker coating.

Model 915, 925 Shoulder:

Model 915 - Low Voltage:

Shoulder type Model 915 is for the use on thin film coatings. It has infinite voltage settings over a range of 1,000 to 5,000 volts. The detector has the same properties as the Model 715 only comes with shoulder strap.

Model 925 - High Voltage:

Shoulder type Model 925 is for the use on thin film coatings. It has infinite voltage settings over a range of 5,000 to 15,000 volts. The detector has the same properties as the Model 715 only comes with shoulder strap.
