EMF + RF Meters
Electromagnetic Field Meter (EMF)
Measures electro magnetic field emissions from electrical power lines and transmission equipment, computer, HVAC, audio/video, and other electrical appliances and equipment. While the evidence of the carcinogenic effect of such electromagnetic emissions is still inconclusive, prudent avoidance is recommended to avoid excess exposure over long periods of time.
Reads milli-Gauss and micro-Tesla on a large 1¼” high display. The display indicates when the object being measured is out of range as well as when the battery is low. Features both standard and maximum hold. Powered by a standard 9V battery lasting approximately 100 hours. Comes with battery, instructions, rubber boot and a soft carrying case.

3 Axis EMF Meter
Simply approach the source at any angle and the triple-axis meter automatically determines EMF (electro magnetic frequencies), eliminating the need for additional calculations. X, Y, and Z axis results can also be viewed independently. Measures electro magnetic fields of extremely low frequency (ELF) from electrical power lines and transmission equipment, appliances, computer, HVAC, audio/video, and other electrical equipment. While the evidence of the carcinogenic effect of electromagnetic emissions is still inconclusive, prudent avoidance is recommended to avoid excess exposure over long periods of time.
Automatically or manually log results with time and date stamps. Holds up to 500 readings which can be reviewed on screen. Features manual or auto ranging, mG (milli-Gauss) and µT (micro-Tesla) scales, min/max and hold functions. The meter has tripod screws and a large 3-line display indicating when the battery is low or is reading over range. Comes ready to use in a soft carrying case, instructions and a 9V battery that lasts approximately 100 hours.

3 Axis RF Meter
Measure the RF strength of Wi-Fi and LAN, cell phone, radio and TV transmission towers, wireless cameras and microphones.
Sper Scientific’s 3-Axis RF Meter 840047 measures RF (Radio Frequency) electromagnetic field strength in the frequency range of 50 MHz to 3.5 GHz. The 3-Axis probe provides simple, accurate, non-directional measurement from any angle. Results are displayed in large digits and a bar graph on a backlit LCD that also indicates maximum or average readings, low battery, and overload. You may set audible alarms a CAL (calibration) factor for a specific frequency or save and review up to 200 readings directly on the meter. Auto-ranging, with auto power off. Comes ready to use in a soft carrying case with belt loop, instruction manual and one 9V battery.
