Surface DC Voltmeter
SVM2
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.

Power Line Meter
The Line EMI Meter measures electromagnetic interference in a single-phase AC power line. It plugs into a wall outlet (mains socket) and requires no battery. It immediately displays total line noise in millivolts (range 1999 mV, resolution 1 mV) in the frequency range 10 KHz 10 MHz (the frequency limits at which sensitivity is of the maximum sensitivity). A speaker plays the sound of the EMI, amplitude demodulated, in order to identify the EMI source (such as an AM or shortwave radio station vs. a motor vs. an electric arc).

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.

Automated Production Testing
Automated production testing is critical in today’s competitive manufacturing environment. Companies can no longer rely on variable costs, non-uniformity, and potential health hazards that come with a laborer-based manufacturing line. This is no less true for sound and vibration tests, ranging from in-process burn-in tests to product validation and verification tests. The measurement tools and intelligence behind present day manufacturing include data acquisition equipment as well as closed-loop control. And while these systems may not take part in the assembly of any goods, they are just as important to ensure quality control for both components coming into an assembly line and products going out.

Digital Telephone Hybrid
DMTH4
The DMTH4 integrates telephone lines, video codecs and external audio sources into the digital bus structure of DM Series processors so these sources operate as though they are another microphone or audio input in the sound system. The unit is much more than just a telephone interface. Instead, it is a complete DM Series digital matrix processor, with a 3-in/24-out digital matrix, automatic mixing and comprehensive signal processing on every input and output. In essence, it simply connects to telephone lines, video codecs and external audio sources instead of mic/line inputs and outputs and integrates seamlessly with DM Series matrix processors.

Suspension Component Test Systems
Acoustic quality, vehicle dynamics and stability, and driver comfort play an increasingly important role in the development of new chassis and suspension systems – both passive and active. Noises in suspension components can cause customer dissatisfaction and lead to high warranty costs and are difficult to diagnose especially on historically-used, noisy hydraulic test rigs. The MB Suspension Component Test Rig (SCTR) enables dynamic simulation of real road excitations and synthesized waveforms, performing industry-standard Force-Velocity and Force-Displacement tests and low speed friction tests, and assessing other NVH and structure-borne noises for comprehensive performance characterization and sound and vibration analyses on a wide variety of chassis components.

UDP Test Tool, Flood Generator, VoIP Readiness Test Tool
The Multiprotocol Network Tester is a freeware, open source tool which enables you to measure quality of your IP network. It can also be used to generate UDP flood or to simulate UDP DoS attack. SIP call is usually established using a SIP session with a bidirectional RTP stream. SIP and RTP protocols are based on UDP transport protocol. UDP uses a simple transmission model without implicit reliability, ordering and data integrity. Each single UDP packet is transferred independently. The quality of a SIP call depends on delays and loss of IP packets in a network. Long delays lead to large RTP jitter and bad sound quality of a SIP call.

Non-Destructive Testing Equipment
BOLT-Tester
BTS(BOLT-Tester) is developed in 2012 after the collapse at SASAGO Tunnel on the Chuo Expressway in Japan. Visual inspection and hammer sound testing are main inspection methods for maintenance and management of anchor bolts in a tunnel. However, these methods have some issues in regard to objectivity and reliability of the results. Pull out testing is also one of a testing method for the soundness test of anchor bolts, however, this method have also some issues in regard to cost and time, and there is a risk to damage the anchor bolt. BTS is simple and cost effective non-destructive testing equipment that solves those issues. BTS measures a waveform of impact force to evaluate the soundness of anchor bolt.

Vibration Testing
Response Dynamics Vibration Engineering, Inc.
We most often characterize a problem first and work from known conditions, and stay in “the known” as we proceed by making sense of what we observe as we move forward. We test and analyze the change in dynamics we are trying to create in real-time, on site, and often make changes to our experimental test plan on the fly as we discover how a system is actually behaving. In doing so we often get meaningful results from which we can make sound engineering decisions in a short time frame. We don't just make measurements and spit out data. We help identify the problem and propose solutions.

Acoustic Probe
AA-Ultrasonic
The AA-Ultrasonic acoustic probe is designed for use on air insulated terminations where a clear sound path between the electrically stressed insulation and the probe is present. The sensor is extremely sensitive and can detect activity below 10pC. The probe has a magnetic base to allow coupling to steel enclosures and a swivel head as so the detecting sensor can be aimed directly at the HV point. Corona in air and surface tracking can seriously damage high voltage insulating surfaces in a way that will ultimately lead to flashover and complete failure of the insulator. This discharge activity creates acoustic emission that can be detected using a high frequency sensor. The magnitude of the acoustic emission is indicative of the degree and severity of the discharge activity.
