Does it need to have the probe plugged in to sense E.M.F.?

no, according to my granddaughter who used it for her science project. it does come with everything you need.

Hi, I would like to know if you need the probe plugged in to detect EMF. I see two conflicting answers below. Is it a yes or a no?

Make sure you have tightened the probes tightly. I have used one for years and never had a problem.

Hold it to where it does not go off and move it towards a power cord or a fluorescent light. It should go off the closer to the power it gets. It does not tell you if it is measuring EMF or RF energy.

No......as far as I can tell. I have it plugged into the 110 here at the house.

only need to hook up one senser.If other is not plugged in it doesn't go off

I has to be plugged in. I was not very happy with this scanner. It has to be cleaned constantly to prevent the little white lines that appear on the scans. I just bought a Doxie scanner.

Yes, the probe has a connector that plugs into the back of the edge unit. No spicing to be done.

Use a volt ohm meter set to continuity and touch the red probe to one prong and the black probe to the other prong. If the meter reads open or over load it is bad.

Not with the included probes, you'd need an amp clamp to do that. Their clamp style probe has low resolution with currents under 1 amp but I've heard their thread-style amp probe is more accurate with those situations.

No. I have one set up on the bench. Apparently it's protected against reverse polarity :-) It shows 0.0 when powered on and the sampling wire is switched (white)

Yes, if you can keep the unit working. Mine only worked for a couple months then broke. After numerous promises to send working probes I tacked it up as a worthless piece of junk with NO support.

No. This is only to find electromagnetic radiation from electricity running through wire. Like overhead power lines. You need a microwave radiation detector for wifi and cell phones. Like this one: Hf35c Rf Analyze (800mhz - 2.5 Ghz) - Perfect for Smart Meters Detection

Yes. The sensor is tethered to the unit I don't recall the exact length, but the probe is in one room and the actual gauge is outside, I get readings with out opening door. Works fine for my needs.

No. The unit must be plugged in to an outlet and powered on in order to function.

By default it needs to be plugged in. I think there are wireless dongles for it also.

No. This is a water/nutrients/solutions only device. You do not want anything touching the probe but water/nutrients/solutions.

The probe only, of course... but keep in mind the readout is ONLY in Celsius, NOT in Fahrenheit!
