Well built meter but uncertain measurements

- Reviewed in the United States on March 4, 2025Color: EMF02R-YellowVerified Purchase
- Reviewed in the United States on January 27, 2025This is a very affordable meter especially considering the functionality provided. The unit is compact and easily handheld. It seems built as well as most digital volt meters and included a charging cable, instructions and a protective case for storage. The display is beautiful and very easy to read while the key functions are all well laid out and accessible through a push of a button. I am concerned since no calibration is provide and there are no user options to calibrate the unit that the readings may be questionable. See attached photos of an overloaded meter reading the magnetic field generated from a small space heater. Also note measurement of an e field at 328 V/M from that space heater. That seems very high as we test our electronics product susceptibility at 200 V/M for automotive use and certification. I think a helpful item to include would be a guide that indicated typical levels present with various consumer electronic products. This would provide a basis on if the readings seen are what should be expected. This may be a very accurate measurement but I don’t have a very good basis of comparison so am a little sceptical.

- Reviewed in the United States on January 18, 2025Color: EMF02R-YellowVerified PurchaseThis is one of the easiest detectors I’ve ever used, funtions are very easy to learn
- Reviewed in the United States on November 14, 2024Color: EMF02R-YellowVerified PurchaseThis isn't a good suggestion to answer questions from those curious to find out what the total emf is in their home. Emails to the company went unanswered. I was looking for an less expensive alternative and this product isn't it.
- Reviewed in the United States on February 21, 2025Color: EMF02R-YellowVerified PurchaseThought it would be more durable for the price. Battery never shows fully charged.
- Reviewed in the United States on October 21, 2024Color: EMF02R-YellowVerified PurchaseIf I did not have this meter I would have damaged my hand further with an Alcatel telephone. My hand has been going numb and tingling the hand I hold my phone. The meter showed dangerous levels of radiation emitting from back a phone heading towards the tower. I no longer hold my phone because it is dangerous thank you so much also I do not go in my front yard for any length of time because of the power lines are in the red thank you so much you may have saved my life.

5.0 out of 5 stars Robustes Messgerät
Als Vine-Rezensent habe ich dieses Produkt „kostenfrei“ erhalten. Dies hat jedoch keinerlei Auswirkung auf diese Review. Das Produkt wird von mir bewertet, als ob ich es selbst hätte erwerben müssen.
Das Gerät macht auf den ersten Blick einen robusten Eindruck. Es liegt gut in der Hand und die Bedienung ist recht intuitiv. Die Tasten sind übersichtlich angeordnet, und das Display ist groß genug, um die Messwerte auch aus etwas Entfernung gut ablesen zu können. Besonders hilfreich finde ich die farbige Skala, die auf einen Blick zeigt, ob die gemessenen Werte im unbedenklichen oder kritischen Bereich liegen.
Allerdings gibt es auch ein paar Kritikpunkte. Die Genauigkeit des Geräts scheint bei sehr niedrigen oder sehr hohen Werten etwas zu schwanken. Ein weiteres kleines Manko ist die Akkulaufzeit. Obwohl das Gerät wiederaufladbar ist, musste ich es häufiger laden als erwartet. Bei intensiver Nutzung hält der Akku nur einen Tag durch, was für längere Messungen etwas unpraktisch ist.
