PORTABLE OSCILLOSCOPE
Great Way to Get Detailed Frequency Information
Anyone familiar with the operation of an oscilloscope will appreciate the incredible low price and full features of the hand held oscilloscope. Connected to a probe (magnetic, electric or RF) you can measure voltage up to 80V AC or DC and check the waveform up to 2MHz. See spikes, RF noise, harmonics. Check for dirty power. Operates on 5 AA batteries, not included. BNC input. Extend the input range to 600V with x10 probe setting.
- Input Impedence: 1Mohm//20pF (standard probe)
- Timebase Range: 0.2 micro-s to 1 hour/div
- Sensitivity: 5mV/div to 20V/div (0.1 mV minimum sensitity)

O-Scope/Spectrum Analyzer for PC
0 to 12 MHz, and Low, Low Cost!
Fantastically simple way to get frequency (and field strength) information from your EMF probes and meters with ACV output. Using your computer and monitor to display, all standard oscilloscope and spectrum analyzer functions are available through the Windows based software supplied.
Look what you can do:
- Look for harmonics or high frequency noise in powerlines
- See waveform, monitor spikes, surges, brownouts
- Compare Electric field to Magnetic field, or to temperature, sound, light or other parameters with appropriate probes
- Great for audio and automotive applications too

Record and Analyze Magnetic Field Signals
Use the handy E-Z Hook "Grabber" tip to track down unwanted RF sources in circuits or hold it in the air as an RF field strength meter!
Uses exotic low barrier microwave detector diodes to give exceptional sensitivity (down to microwatt levels). A great inexpensive way to check for RF. Max RF input: 100 mW (2.23 V into 50W). Max DC input: 50 VDC. 90 day manufacturer warranty. Made in USA.
Some experts warn against induced voltages of 20 mV or higher as they can theoretically interfere with the subtle cellular activity. Simply touch this sensor with a finger and know instantly what effect external fields are having inside your body (where it counts!). Will help you detect irritating sources of electric field which may not otherwise be obvious. (Note: this item is a sensor. To use it you must plug it into a voltmeter or DMM.
