Hi Pot Meters
The HI Pot Device is designed to Hi Pot de-energized 15kV class cables. The tool transforms 18 Volts from the battery to approximately 8,000 volts DC. When the battery is installed and the safety switch is in the closed down position, the unit is in voltage detection mode. The unit should be in this position when installing the device, as it will sound a warning alarm if you approach an energized source. When the safety switch is lifted and the toggle switch is switched up, the unit is in the Hi-Pot mode and the high voltage DC is being applied.

Directional Microphone
MI-8100
MI-8100 is a shotgun type directional microphone which sharply catches the intended sound. This directional microphone is helpful for the removal of background noise in the simple sound source exploration and in abnormal sound detection. Flat frequency characteristic from 50 Hz to 20 kHz and sharp detection with high S/N ratio provide high sensitive detection of various sound coming from the specific direction. By combining the acoustic vibration monitor BL-1100, only the intended frequency or sound is focused and caught clearer.

Sound Level Calibrator
521
Accepted internationally 1 kHz represents the "0 dB" reference point of A, B, C Weighting and other filters utilized in acoustic measurement. The Pistonphone - a mechanical sound source - offers a slightly higher degree of accuracy at a substantial increase in cost. In addition, the 200 or 250 Hz operating frequency is mechanically limited and not suited for measurements of filtered inputs. The 0.2 dB accuracy is quickly lost in the 0.7 to 1.5 dB tolerances acceptable for weighting filters at frequencies around 250 Hz.

Environmental Noise Monitors
Noise is one of the most complained about aspects of the environment, as not only does it have the potential to affect quality of life, it can also be difficult to monitor and therefore control. This type of noise is generally called environmental noise. There are many man-made sources of environmental noise, such as wind turbines, industrial sites, roads and traffic etc. If you are looking for equipment to measure noise in the workplace, look at sound level meters.

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.
