TM900 Telephone Test Set

Catalog Number: TM900

Whether installing, servicing, or maintaining voice service and data on copper lines, you’ll want the newest member of the Nautilus telephone test set family at your side. The TM900 offers a new LCD screen display showing “caller ID” and related features, plus a comprehensive phone book including ten number “last number redial”, direct display of line voltage, loop current, ringing frequency, and the ability to receive DTMF strings. All while still offering protection of digital traffic and hands-free speakerphone functionality, plus much more. With this innovative design, Tempo continues investment in “butt-in” test set technology, setting new, unmatched standards in both quality and customer satisfaction.

The TM900 butt set gives meaning to the term “weatherproof”: This award-winning, waterproof case design allows technicians to operate with confidence in even the most extreme weather conditions. Other key advancements include digital service and high-voltage alarm, and a quick-release, non-metallic belt clip composed of glass-filled nylon. This combination of rugged technology enables Tempo to offer the best warranty in the industry – 3 years.
