Received quickly and works well. I can't vouch for accuracy as I don't have anything to compare it to, but I put it close to my smoke detector (they all contain Americium) and it did pick up the radiation. Very easy to use, highly recommended!

Es un excelente equipo de medición de radiación ionizante, lo verificamos con la radiación de fondo del lugar en donde nos encontramos y es muy preciso! Obviamente al igual que cualquier otro instrumento de medición si se requiere conocer su porcentaje de error o fluctuación para mediciones mas certeras se debe hacer la calibración correspondiente con un laboratorio acreditado! Sin embargo, los datos que ofrece son muy cercanos a los reales! No le pide nada a marcas más avanzadas en este tipo de equipos de medición! Y la realidad de las cosas es que este tipo de equipos ya se han vuelto una necesida, debido a que la radiación ionizante se encuentra en muchos lados, no sólo por la presencia de plantas nucleares, existen sitios en diferentes partes del mundo que tienen radiación ionizante ambiental muy elevada o equipos que la generan, y es importante conocer los valores de referencia para no exponerse innecesariamente a la radiación ionizante debido a los efectos biológicos que pueden producir, ya sean deterministicos o estocásticos (ICRP, 2007). Lo recomendamos ampliamente! Saludos cordiales!

A very affordable and well made item with a large, colorful display that is easy to read and with pages and pages of different displays allowing you to customize what you want to see and how you want to see it. This is a "smart" device that can link to your PC and through the cable, the battery is kept charged for two or three days of field surveys. More if you turn it off between uses. I bought this just for the fun of detecting uranium in the Chinle and Morrison geologic formations of the Colorado Plateau and seeing for myself that genuine dinosaur bones and petrified wood from those formations can be quite radioactive. As mentioned, I bought this just for fun and not for any practical, safety or economic reasons. Unfortunately I have not had an opportunity to use the device for its intended purpose, but I have confirmed that the unit is functioning well. It sure would be nice to have a counter that displayed actual EVs of the radiation so that I could tell just what radioactive elements are present, but they cost more and for me, it just for a whim more than anything else. When visiting dinosaur museums, I'll turn off all alarms and sounds so as not to panic the public if a bone proves to be a bit "spicy" and I recommend others do so too.

Although the item is lightweight, the materials that were chosen seem to be sturdy enough to survive the everyday handling that it undergoes. Even when the levels of illumination are low, the huge color LCD display is bright and simple to see. When I utilized this device in a low-light condition, I must say that the screen functioned quite well, providing me with clear readings without causing my eyes to strain. You can easily move between the various alarms and settings because of the menu's user-friendly interface, which has navigation buttons that react quickly. I discovered that its measurements were very accurate, with only tiny discrepancies, when compared to the readings of other professional equipment that I have in my laboratory. When I am monitoring ambient levels or testing particular things for contamination, it is comforting to know that it has the capability to deliver dependable results. Depending on the location in which I am working, the five various forms of alarms—sound, vibration, light, data recording, and email notification—provide me with a variety of alternatives to tailor the manner in which I get alerts. This is really helpful.

Ahora si llegó el producto bien no me lo cambiaron
