TriField Meters
This TriField meter is essentially the same as the TriField Original except it has a different electric field range, measuring between 0 and 1000 V/m. This is considered a much more useful range for measuring the electric field strength in and around domestic properties. This also provides greater sensitivity for the paranormal investigator who uses the electric field function. For locations such as those very close to pylons please refer back to the TriField original ALT1. Battery and instructions included. Calibrated to 50Hz.

Independently measure electric fields, magnetic field and radio/microwave fields with the one meter. The original TriField ® Meter combines all the features needed for fast, accurate measurements of electromagnetic fields. Scaled to indicate the full magnitude of currents produced by each type of field inside a conductive body it "sees" much more than many other electromagnetic pollution meters. Easy-to-see large analogue readout; 3-axis electric & magnetic sensitivity for fast surveys; 2 separate scales for magnetic field readings; hand-held portability and simplicity. The meter 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 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, and many types of radars. This meter is calibrated to 50Hz. Battery and instructions included. Calibrated to 50Hz.

So highly sensitive it will detect the presence of body parts. What makes this unit so useful for paranormal work is the squelchable audio tone which alerts the user to activity in the vicinity of the meter. The TriField Natural EM Meter was designed to do field measurements for special research. It detects changes in extremely weak static (DC or natural) electric and magnetic fields, and signals with both a tone and the movement of a needle-type gauge if either the electric or magnetic field changes from previous levels. A radio and microwave detector is also included, which reads radio power directly. Because man-made AC electric and magnetic fields are very common and could interfere with readings of static fields, the meter has been designed to virtually ignore AC fields. Normal construction materials do not block magnetic fields, so the meter can be placed indoors and will work equally well, and due to the built-in tone, it can be used in the dark, and will sound the tone at whatever level of field the user sets. Operates on a PP3 9 volt battery (included) and covered by a one-year warranty. Battery and instructions included.

Model 2 of the Trifield Natural EM with Coil has the following additional features: A socket for an external power supply for continuous or prolonged use. An input jack for the included high-sensitivity magnetic coil. The SUM setting in Model 2 can be used for early warning of any unusual atmospheric electromagnetic activity, such as geomagnetic storms or ball lightning. In this setting, it does not falsely trigger when people walk by. It detects changes in extremely weak static (DC or natural) electric and magnetic fields, and signals with both a tone and the movement of a needle-type gauge if either the electric or magnetic field changes from previous levels. A radio and microwave detector is also included, which reads radio power directly.
