General Purpose Radiation Survey Meter/Geiger Counter
Rad 100™
The RAD 100™ is a general purpose radiation survey meter/geiger counter that detects and measures alpha, beta, gamma, and X-radiation. It is intended for personal safety and educational purposes. Like the popular Radalert® 100X, the RAD 100™ features a 3-second update on its digital liquid crystal display (LCD). The LCD shows the current radiation level in your choice of microSieverts per hour (SI units) or mR/hr for gamma radiation measurements. For mixed sources (alpha, beta, gamma) the CPM mode is recommended. This instrument also offers an accumulated total and timer function, up to 9,999,000 counts and 40 hours. A red LED blinks and a beeper chirps with each count (the chirp can be muted). This is a professional instrument that is also easy to learn to use and to operate, and carries the industry leading Medcom warranty (2 years overall limited to 1 year on the GM sensor). Many instruments designed by the Medcom team are still working perfectly after 30 years of use, so this instrument should provide a lifetime of useful information.

Frequency Extender
DC100
The DC100 system can be installed in the HP8568B(see H96 option below) without compromising the performance of the original instrument. The spectral purity and power accuracy of the primary band ( 100hz to 1.5Ghz) are insured from corruption by careful design of the DC100 system. Additional protection of the primary band is guaranteed as the DC100 system is automatically switched off (all power removed) when in primary band operation.

Frequency Response Analyzers
350C Series
Venable Model 350c is the 3 channel successor to the original workhorse Model 350a/b that launched in 1986 and established Venable Instruments as a market leader. The contemporary 350c Series incorporates a 3rd channel, allowing the user to measure more transfer functions simultaneously with one sweep, such as source and load impedance. The 350c is the only frequency response analyzer in the industry that can measure absolute phase, using a reference channel.

High Frequency Transformers
Osborne High Frequency Current Transformers operate at frequencies higher than 50/60 Hertz. Their purpose is to reduce high frequency system currents to lower values that are appropriate for instrumentation and/or protection circuits. They have been designed to meet specified current ratios, and burden impedance at a specified transformation error. One area of unique Osborne expertise is in designing for phase shift when high frequency current transformers are to be used for power measuring applications.
