It identifies radioactive contaminated foods and construction supplies. It can also can easily measure the level of radioactivity according to the power level of ion radiation (gamma radiation and beta particles flux). For this reason the radiation can change the molecular structure and cause the nucleus and electrons to create a positively charged ion. Hence these positively charged ions can then penetrate into materials and cause damage. Therefore normal radiation exposure is 0.08 to 0.18 Sv/h. So anything greater than 0.4 Sv/h is too high. (0.01 mSv/h = 1 mcR/h). ## Customer Reviews ### ⭐ What a waste of time and money!!! *by on Reviewed in the United Kingdom 10 May 2019* The Soeks Ecovisor F4 device is basically a great idea, but is still in its infancy! Therefore no recommendation to buy! Better wait 2-3 years until the technology/software works without problems and is mature!The communication with Soeks has been very difficult. Well over 20 e-mails were necessary, a catastrophe! What a waste of time!After 14 days of proper use the temperature sensor was already broken. The temperature fluctuated arbitrarily from approx. 30 Β°C / 86Β° F upwards to over 80 Β°C / 176 Β° F. Therefore all measurement results were falsified. A wholesaler confirmed this problem by telephone, which had been known for a long time!The problem was initially denied by Soeks. It was claimed that the temperature display had no influence on the measurement. This cannot be true, because the results at different temperatures at the same measuring point are different. This was also confirmed by this leading wholesaler. The manufacturer also tried to sell him this opinion as a fact. However, he understood that it was not true.In addition, the EMF measurement only works correctly when the battery is fully charged. So you have 5 minutes for a correct measurement. Disaster!The consultation with the wholesaler showed that he has numerous defective devices, all defective because of the EMF battery problem and temperature sensor. Even the dealer does not get a replacement from Soeks. The drawer is already full. That is a cheek, I think. The wholesaler complained about the bad service of the manufacturer and emphasized that the idea and the patent are great, but the current implementation is only stress. Unfortunately, the problem seems to be more man-made than technical.The warranty case was initially denied despite naming the known defects. Only after threatening to publish a field report was a replacement device reluctantly offered. The defect was proven by a photo.As it turned out after sending, the EMF measurement is definitely defective, see photo. The microwave shows completely different values on the defective device as well as on the new device. Catastrophe! (The time displayed on the devices does not match. But this is only due to the setting)The way to the exchange was also a disaster! Despite guarantee case I had to take over import tax as well as time and travel expenses to the customs at own expense. Soeks refused until today any financial compensation of my expenses. I had additional expenses of ~80 dollars!!! Also the return costs of the defective device must carry the customer! Cheek! Despite the warning to publish my experiences, the company showed no understanding. The compensation was refused. Therefore now the publication of my experiences! Time expenditure altogether at least 12 hours! Nobody pays this expenditure, only the customer himself. Normally one should be able to assume with a warranty case that the company and/or the manufacturer carry all costs of the exchange. In this case the customer has to pay for errors and defects of the device himself. Only the postage costs for the new device were paid. Unbelievable! The guarantee conditions say nothing about who has to bear the total costs or how the distribution of the costs is. Attention! This is a trap! The company silently and secretly commits the customer for all additional costs of the exchange, even though it is a production-related error! It is simply unbelievable how costs are saved here and put on the customer. Actually it is self-evident that a warranty repair or a warranty exchange does not burden the customer in any way. This company thinks differently. Therefore save time and stress and rather wait a few years or buy an alternative device somewhere else. ### ⭐⭐⭐⭐⭐ This things great!! Won the Science Fair with my 12 Yr Old using it *by on Reviewed in Germany 3 August 2019* I love this device. My son and I and shopkeepers and other parents from the school all are amazed at the wealth of information Soeks 4 in 1 provides. We live in a country they cheat left right and center with everything....well not with this gadget at hand. Just beware the findings may be shocking as to what you have been led to believe is so pure and healthy. Its a fun and productive device to have, we use it often and now have a sure system of what to eat and drink where and when for good health. ### ⭐⭐⭐⭐⭐ DziaΕ‚a *by on Reviewed in Poland 11 October 2024* J.w. ## Frequently Bought Together - SOEKS EcoVisor F4 Geiger Counter Radiation Detector Dosimeter Nitrate Tester EMF Electromagnetic Electric Magnetic Field Device Water Quality TDS Meter Portable Electronic Touch Screen Easy to Use - EMF Meter,Advanced GQ EMF-390 Multi-Field Electromagnetic Radiation 3-in-1 EMF ELF RF meter, 5G Cell Tower Smart meter Wifi Signal Detector RF up to 10GHz with Data Logger and 2.5Ghz Spectrum Analyzer - TriField EMF Meter Model TF2 – #1 Handheld EMF Detector for 3 Types of Electromagnetic Fields: Radio (RF), Magnetic (MF) and Electric (EF) - Measure 5G, Cell Towers, WiFi, Bluetooth, & Smart Meters --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/58934336-ecovisor-f4-soeks-portable-4-in-1-tester-nitrate-water](https://www.desertcart.tn/products/58934336-ecovisor-f4-soeks-portable-4-in-1-tester-nitrate-water) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-22*
