  • Surface DC Voltmeter

    SVM2 - Alpha Lab, Inc.

    The SVM2 has high sensitivity (resolution), and can detect even a 1 volt charge anywhere within its full range of +29,999 to -29,999 volts. Thus it is easy to measure whether a given process is increasing or decreasing the static electricity present, even if the increase or decrease is by a tiny fraction. The meter reads the actual static signal, but it also captures and stores the highest positive and highest negative signals that were experienced since the last time that the "Reset" button was pressed. These peak + and can be displayed at any later time. The peak function has a "window" time of 0.005 seconds (which is much faster than the display) so even very quick peaks are captured and stored. There is also a user-settable alarm. The alarm will sound if the signal (whether + or -) ever exceeds the value set by the user for at least 0.005 seconds. The alarm can be reset or muted at any time.

  • Tome & Probe Kit

    Daerim Electronics Co.

    Without direct metallic contact, this kit can quickly and accurately trace and identify the specific wires within a bundle, at a cross-connect point or remote end. It works with all types of wire and cable, including twisted pair, multiconductor cable, de-energized AC wire, speaker wire, coaxial, security & alarm cable and LAN cable. TRACER-A(DR-77A) is a tone generator, which applies its tone signal to a wire pair that the user want to identify at the far end or within a bundle. For the easy access to wires, it has test lead wires with ABN clips and modular plug(RJ-11). Belt clip is convenient for the easy carry. Independently it can work to test polarity and continuity. TRACER-B(DR-77B) identifies the specific pair through the bell sound and LED light. Its recessed on/off control button prevents the accidental push. TRACER-A & B can be purchased separately.

  • Intelligent Automatic Touch Screen Control Oxygen Index Meter

    Shanghai Dean Electrical Co., Ltd

    1. Full-color touch screen control. You only need to set the oxygen concentration value on the touch screen, and the program will automatically adjust to the oxygen concentration balance and sound prompt.2. The step proportional valve is adopted to greatly improve the accuracy of flow control, and the closed-loop control is adopted to automatically adjust the oxygen concentration drift program back to the target value during the test, which avoids the disadvantage that the traditional oxygen index tester cannot adjust the oxygen concentration during the test and greatly improves the test accuracy.

  • Telos Systems

    Linear Acoustics

    Telos Systems—part of the Telos Alliance—was founded in 1985 by Steve Church, a talk show radio host and engineer who was dissatisfied with the poor quality of the on-air telephone calls on his shows. He was also an Engineer determined to do something about it. The resulting Telos 10 telephone interface system was a great success, inspiring Steve to build a business to make and sell the systems. Telos Systems has since become the industry leader in broadcast telephone systems and IP and ISDN codecs. The breakthrough Telos Zephyr audio codec, for example, is one of the most successful digital broadcast products in history, with more than 21,000 in use worldwide. Telos telephone hybrids and on-air talk show systems set the performance benchmark for the industry, and we continue to pioneer groundbreaking technology that pushes boundaries and gives broadcasters the telephony solutions they need for reliability, efficiency, and the best possible sound quality.
