  • Remote End Cable Testers

    XLR Sniffer/Sender - Sound Tools

    Designed by Rat Sound to deal with the "real world" of pro audio, the SoundTools Sniffer/Senders are the perfect tools for live environments. Test snake lines and cables when the ends are at a distance and avoid running extra cables just to test. Utilizing phantom power the Sniffer end can quickly test snake lines in minutes. The aluminum barrels eliminates the problem many testers face with solder joints failures and the unit will never rust. 3 simple LED’s will instantly diagnosis your cable as it tests for every possible shot, open, or cross wire in XLR cables. If the LED’s read all green you cable will work!

  • Profiling CTDs

    Sea-Bird Scientific

    A CTD measures Conductivity, Temperature, and Depth. Despite the name, all CTDs actually measure pressure, which is not quite the same thing as depth. The relationship between pressure and depth is a complex one involving water density and compressibility as well as the strength of the local gravity field. The CTD data can be used to calculate salinity, density, sound velocity, and other parameters of interest. The term CTD is often used today to describe a package that includes the actual CTD as well as auxiliary sensors to measure other parameters (such as dissolved oxygen, pH, turbidity, fluorometer, altimeter, etc.) and a water sampler to collect water samples for later analysis in the lab. The term Sonde is sometimes used as an alternative to CTD.
