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. 

 euro 75

emf radio/microwave alarm is the size of a small pager.  (US), this detector is ideal for anyone trying to find out exactly what's emitting radio or microwaves, including hidden sources. Just turn it on, select the sensitivity level you want, and put it in your purse or pocket.  [Actual size is 2.25 inches high X 1.6 wide X .75 thick.]

RF METER

Accuracy in the FM, TV and cell tower frequency range (30 MHz – 2.4 GHz) is +/-25%. Sensitivity is low by 50% (-3 dB) at the frequency limits .5 MHz and 3 GHz. (Sensitivity is 25% at 5 GHz. That is, you must multiply the reading by 4 when measuring microwaves at that high a frequency. At 10 GHz, sensitivity is about 10%.)

A High-Pass selector switch allows you to measure either the full bandwidth ("Wide" = 0.5 MHz – 3 GHz) or to apply a high-pass filter ("Narrow" = 6 dB/ octive rolloff with a knee at 100 MHz) that effectively allows only 100 MHz to 3 GHz through. In practice, this high-pass selector function can be used to estimate one additional parameter: the average frequency of the RF (if it is in the range 10 MHz – 500 MHz).

euro 150

EMF EFM electromagnetic electric microwave meter

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.

 A circuit amplifies these signals and gives them the proper frequency-weighting (sensitivity increases linearly from 30 Hz to 500 Hz, but with some residual sensitivity up to 100 MHz). A unique network combines the three coil outputs nonlinearly to approximate a true magnitude. The meter is sensitive from 0.2 to 100 milligauss full scale at 60 Hz (or 0.1 to 50 milligauss full scale at 120 Hz, etc.) with a resolution of 0.2 milligauss in the sensitive range. Accuracy is +/-20% at mid-range. A version with flat frequency response (instead of linear sensitivity increase) is also available for the same price

It is the function that allows analyzer  to visualize on display and on the print if one of the controlled parameters overcome the set-up limits. On set-up pages can be set, up to 4 minimum or maximum alarms, to be chosen among the 8 available parameters. These alarms with transistor exit, if connected to MA4 external module by means of 4 relays, can signal the need of intervention

THE ANALYZER IS A ENERGY ANALYZER POWER ANALYZER  

is a portable version  electric energy analyzer. In fact, inside the case, type 24 hours you can find the analyzer, three amperometric clamp meters and if requested - a thermal printer is possible to connect Studied for a mobile duty,The analyzer is useful to do the measure campaigns on the three-phase electric plants with unbalanced loads. There's no need of any fixed installation. You can leave the analyzer and observe all the parameters of a plant in required time, simply by supplying the instrument to the 230 VAC net and further on by connecting the amperometric clamp meters and the voltmetric terminal. Our analyzer is produced in various versions that correspond to the user requirements. can have all the optional function  analyzer installed and it has got the possibility of the connection to PC and the observed data processing

The printer lets to print the data in the fixed intervals, the sheet of the printing has got as the heading month/day/year - hour/minute/second and following the measures of the basic three-phase and single phase parameters. The sign '#' before the parameter means that the alarm is set on that value. The sign '*' before the '#' means that the value has entered in alarm. The alarms are always positioned on the single phases. If a parameter under observation goes in alarm, the printer starts printing. If this alarm finishes, the next printing stars to be a proof of the variation.

 The Earth Magnetometer with battery and probe rod. It weighs only 18 ounces (= 510 grams), and runs about 8 hours on the included standard 9-volt alkaline battery. It measures difference in field strength to accuracy of +/-0.5% of the difference, either for point-to-point or time-to-time measurements. In other words, if one location is 2.00 milligauss (200 nanotesla) stronger than another location, the Earth Magnetometer will indicate that difference to accuracy of +/- .01 milligauss or 1 nanotesla.

    This magnetometer has a magneto-resistive sensor, which uses the spins of electrons flowing through a circuit, rather than their charge, to measure magnetic field. This type of device most closely resembles a “flux gate” magnetometer, but the magneto-resistive technology is newer, smaller, less expensive and intrinsically more stable over temperature.
