TESMEN HOUND-200 EMF-Messgerät, 3-in-1 tragbarer Elektromagnetfeldstrahlungsdetektor für EF RF MF, WiFi-Signal, zur Verwendung bei EMF-Inspektionen zu Hause und im Freien sowie Geisterjagd - Grün

Top

super Messgerät, einfache Bedienbarkeit und Manual verständlich geschrieben!!!

L'appareil permet de mesurer 3 types d'ondes. L'écran est très lisible et efficace facilitant la détection d'ondes nuisibles dans un local, une pièce ou l'entièreté d'un appartement (dans mon cas). Le boitier est bien éclairé et paraît assez solide. Un étui et 3 piles LR03 sont incluses.

Alles Super geklappt

Macht was es soll und geht leicht zu bedienen.

Funzionale, semplice da utilizzare. Non starete più in ufficio accanto al modem, né vicino ai cellulari. Esaustivo per chi dice ancora che non fanno male le antenne 5G ed è sorprendente 🙈 vicino ai semafori con telecamera ! Istruttivo!!!

Top Gerät und über Akkustik und Optik sehr einfach in der Anwendung.

測定範囲が広いので、ICNIRP基準値に近づけます。ただ電磁波測定に詳しく無い方は少し勉強は必要です。

In our highly electric dependent society today we are exposed to electro-magnetic fields (EMF) from all electrical sources ranging from power transmission lines outside our homes to the electrical wiring, and appliances and devices inside our homes. As well we are now exposed to increasing amounts of radio frequency radiation (RFR) coming from our cell phones, wireless routers, cordless phones, Bluetooth devices as well as the microwave oven. The long term health effects of exposure to this low energy radiation on the human body has still not been conclusive and recommendations on safe exposure limits vary from country to countryWhile scientific studies are still ongoing and regulating bodies yet to establish safe limits, I myself would rather err on the safe side and limit my exposure. I have always wondered about the amount of EMF and RFR exposure I am getting at home. As I write this review, I am in my home office with a cordless phone base station sitting on my desk next to the computer monitor, and the home wireless router is on a shelf about 3 feet above my head.Professional EMF meters to measure EMF levels are fairly expensive as they are certified to be calibrated to standards to give accurate readings and not typically for the lay person. So when this Tesmen EMF meter was offered by Amazon at a very reasonable price ($40 at the time of this review) my curiosity and interest was piqued. At this price point the meter is certainly not professional grade and there is no certification of calibration so the measured readings may or may not be the correct value. However, for me I am satisfied to get even approximately correct values as well as the ability to make relative comparisons of EMF values between different locations.Upon opening the package, I was quite impressed with the contents: The EMF meter (more on this below), a carrying case, three Duracell AAA batteries to power the meter, and a thick user manual containing detailed instructions in six languages. The manual is even written in a grammatically correct and understandable fashion—at least for the English and French sections, I can’t confirm the others.The EMF meter is all-plastic construction but with the batteries installed has a decent weight and seems of quality construction. There is a decent size display screen measuring 1.5 in W x 1.75 in H and all the control buttons are below the screen. Above the display screen is pulsating green LED in the pattern of the ionizing radiation symbol (a trefoil), which is puzzling since this meter does NOT measure ionizing type radiation (think radioactivity). The screen can only display one type of field measurement at a time (either electric field or magnetic field or radio frequency). The large red ‘Function’ button below the screen allows switching the display between the different field measurements. When turned on, the screen displays the instantaneous reading in large font and also peak or highest measurement in smaller font. As a visual alarm, the colour of the screen background changes from green to yellow to red as the measured levels increase: green is supposed to represent a safe exposure level, yellow represents is a warning of increasing intensity and red indicates very high exposure levels. Now as I mentioned earlier, as there are no universal standards yet on what constitutes safe or acceptable exposure levels, this colour code has been arbitrarily set by the manufacturer. The Table on page 12 (English section) of the user manual shows the intensity levels at which the screen colour changes. (BTW, the numbers in the Table are off by a factor of 10: for example for RF levels, the table indicates ‘safe’ or green for 0.001 -1 mW/m2, yellow for 1-4 mW/m2, and red for 4-100 mW/m2 but when using the EMF meter green is actually 0.01-10 mW/m2, yellow is between 10-40 mW/m2 and red is over 40 mW/m2. Similarly, both the magnetic and electric field values given in the table need to be multiplied by 10 to correspond with the EMF meter). The meter also has an audible alarm in the form of a clicking sound whose frequency increases with increasing measured field intensity (sounds like a Geiger counter). Fortunately, this sound can be turned off if you find it annoying as I did.With this Tesmen EMF meter in hand I went around the house measuring various the fields from different electronic devices and appliances. Some high levels were expected from certain devices but I also found some unexpected surprises. First, as expected the wireless router in my office gave off very high RFR (>150 mW/m2, red screen) when the meter was placed next to it, but when I moved the meter to where I am sitting just 3 feet away, the RFR fell to the safe zone (~1 mW/m2). Unfortunately, the Tesmen meter only measures radio frequencies between 50 Hz - 3.5 GHz. My wireless router is dual band: 2.4 GHz and 5 GHz, so the EMF meter will not be measuring any of the 5GHz radio frequency radiation from the router. I could still be exposed to higher levels of RFR than indicated when sitting at my desk. The base station for the landline cordless phone sitting on my desk emits periodic bursts of high intensity RFR from its antennae to maintain communication with the cordless handsets even when the phone is not in use. In the kitchen the microwave oven (2.4 GHz) leaks enough RFR around the door to turn the meter red when placed right next to the microwave. However, when moved to three feet away, levels were back into the green ‘safe’ level. From now on, I will stand at least three feet away from the microwave when heating up food. And now for the surprise findings: my favourite recliner in the living room sits directly above the air handler downstairs in the basement for the heat pump. The magnetic field measured from the floor up to the seat height of the recliner was high enough to cause the meter’s screen to turn red. There is a large blower motor and supplemental electric heating elements inside the air handler which may be the source of this magnetic field. I think I will relocate the recliner. Also the electrical wiring running from the electrical panel and along the ceiling of the basement created large magnetic fields that can be measured on the floor above. Other surprising sources of magnetic fields include light dimmer switches and surge-protected power bars.While the Tesmen EMF meter may not be professional grade with calibration/certification, it is a decent quality device that has allowed me to identify and measure relative intensities of various sources of EMF and RFR around the house and take measures to mitigate exposure.

Diese Messgerät für Hausbedarf ist in Ordnung, aber nicht für Profi

Grundsätzlich ist das ein gutes Gerät mit vernünftiger Messleistung!Mich stört etwas dass das Messesymbol oben die ganze Zeit wie eine Lichtorgel blinkt!Es wäre wesentlich seriöser wenn das nur bei entsprechenden Messwerten anspringt bzw wenn sich die Geschwindigkeit des Blinkens je nach Messwert ändern würde!

Die angezeigten Werte sind nicht nachvollziehbar bzw. stimmen mit anderen Geräten nicht annähernd überein. Sie sind meist viel zu niedrig.

Ein sehr gutes Produkt und der Preis ist unschlagbar. Hier kann man nichts falsch machen.
