The PPS36 DepthWatcher System is a portable device that runs on batteries or external power adaptor and has a LCD display where an slickline or coiled tubing operator could see actual tool depth, line speed, and line tension during a slickline job.

This device is also equiped with 3 additional 4-20mA channels designed for measuring other parameters. It could be operated on a stand alone mode (Memory) or on a real time mode (SRO) with the use of a computer to display depth, speed, tension and two channel values.

The PPS36 system uses a NEMA 4 type of enclosure constructed for either indoor or outdoor use to provide protection to personnel against incidental contact with the device and to the device against falling dirt, rain, snow, etc.
