The Trifield Meter combines all the features needed for fast, accurate measurement of EMF pollution.
This is the only meter that combines measurement capability of electric, magnetic, radio and microwave frequencies.
It independently measures electric and magnetic fields.
Most homes and offices have hot spots with strong artificial electro-magnetic fields, where chronic exposure may cause mental or physical problems. Even the EPA names these fields as suspected carcinogens.
The Trifield meter has three separate sensors allowing independent measurement of magnetic fields, electric fields and RF or radio / microwave fields. It can help you detect defective equipment, determine safer distances for operating equipment and test better shields around your equipment.
Use it to measure high MAGNETIC fields around TV screens, clock radios, computer monitors/disk drives, electric typewriters, and many other common appliances in the home, car and office... AND power lines near the home.
Measure high ELECTRIC fields around such sources as computer monitors, TV's, fluorescent lights, improperly grounded electrical equipment, and electric blankets (especially if the AC plug polarity is reversed) - even when in the OFF position if plugged in!
Detect and measure RADIO / MICROWAVE fields around CEL cellular phones, microwave ovens (check for leaks, door sealing, etc.), CB radio transmitters, etc. A reading of .2 mW/cm2 at a distance of six feet suggests a leaking microwave door seal.
Depending on the position of the knob, the meter detects either frequency-weighted magnetic fields (two separate scales) or frequency-weighted electric fields in the ELF and VLF range. The device has significant sensitivity at 100,000 Hz, well past the 17,000 Hz horizontal scan of video displays. The radio / microwave setting can detect up to three billion Hz (3 Ghz), which lets you gauge radio-wave power, CB and cellular phone equipment, as well as many types of radars.
If you hold the meter in the center of a room and tip it to various angles, the magnetic reading will stay approximately the same regardless of which way you tip or rotate it. The electric reading is similar, although the presence of your body alters the actual electric field, so readings will vary more. The radio / microwave setting reads the full power of radiowaves when the meter is pointed toward the source.
The only meter which combines magnetic, electric and radio / microwave detectors in one handheld, compact, portable, time saving, easy to use instrument, allowing fast & accurate coverage of the entire nonionizing electromagnetic spectrum!
3-Axis measurement (three dimensional) & detection of electric and magnetic fields, which allows QUICK scanning of offices, homes, hallways, powerlines and vehicles, etc.
Independently measures / detects electric field and magnetic fields and is properly scaled to indicate the full magnitude of currents produced inside a conductive body.
Continuous sampling analog readout.
Detects either frequency-weighted magnetic fields (two separate scales) or frequency-weighted electric fields in the ELF and VLF range. It has significant sensitivity at 100,000 Hz, well past the 17,000 Hz horiontal scan of video displays.
Magnetic and Electric settings measure TRUE magnitude, a feature usually only found on very expensive meters.
One-Year limited warranty and will continue to perform indefinitely with reasonable care!
