  • Electroacoustic Analysis System

    CRY6151 - CRYSOUND

    CRY6151 Electroacoustic Analysis System is a full-featured electroacoustic device tester launched by CRY Sound. It has a history of 10 years. It is powerful and stable. It can measure the performance indicators of headphones (USB, Bluetooth, common), microphones (electret, MEMS, moving-coil type), headphone and microphone assemblies, receivers/headphone speakers, speakers/loudspeakers (common, Bluetooth), communication helmets, loudspeaker crossover devices, and other electroacoustic devices, such as sensitivity (SPL), impedance, distortion (THD), resonance frequency F0, left and right headphone balance, left and right headphone position, phase polarity, microphone current and voltage, SNR, microphone directivity, speaker's TS parameters, telephone receiving and sending loudness ratings, etc. Its test frequency range can be up to 20 Hz - 20 kHz.

  • Pathfinder Locating System

    The STICK™ - Rycom Instruments, Inc.

    Built with Pathfinder SAF Technology™ at its core, the Stick offers RYCOM’s most ophisticated technology in an economical package. Pathfinder SAF Technology™ is the heart of our premium locators, now RYCOM is applying this proven technology throughout the entire product line. From crowded easements, to long runs of pipe, to the most demanding of locating environments, users can depend on The Stick. Dependability is not only driven by the internal technology, but The Stick is built to last with an aluminum housing and sealed against weather. The ruggedly designed and well balanced receiver includes an LCD screen providing relative and actual signal strength, as well as a speaker for variable audio pitch. A peaking signal response allows the user to minimize interference and maintain the locate on the target conductor. The Stick cable and pipe locator offers multiple active frequencies — from 50Hz to 82kHz — ensuring flexibility to match the needs of the most complicated locating environments. Transmitter functions include transmitter induction, coupler induction and direct connection. Whether the locate is measured in feet or miles, with automatic impedance matching from 5 ohm to 25,000 ohms and 3 watts of output power, The Stick will meet the challenge. Rycom Instruments®, Inc. locators are designed and manufactured to make utility locating as accurate as you need and as simple as you want.
