Ask a Question
  • For the SOEKS EcoVisor 5-in-1 EMF function. When using the EMF tester is the detection range from 200 MHz - 8 GHz? If not, what is the range?

    The detection range is for the most harmful to human bodies "low electric filed frequencies" is from 20 Hz to 2 kHZ (2000Hz). The frequency range you mentioned (200,000 Hz - 8,000,000 Hz) is just way too high and has no effect. Putting it simply, you don't even need a meter to measure those high frequencies. If you have a cell phone reception or a Wi-Fi signal or a Satellite Dish or a TV Antenna or a Radio signal, it means those high frequencies you mentioned are already there. On the other side, it's important to protect yourself from the low EMF frequencies as described by the WTO below. Those frequencies may come from various electric and electronic devices, household appliances, smart meters, high-voltage power lines, cell phones, microwaves, hidden electrical wires, computers, TV's, monitors, some Wi-Fi routers and much more. So use the EcoVisor EMF meter to TEST, DON'T GUESS!

    Additionally, the EcoVisor also tests for Magnetic Fields in the range of 0.08 - 20 A/m (Ampere/meter) or 0.10 - 25 uT (micro-Tesla). The magnetic fields are produced by electric currents from appliances, house wiring, low-voltage distribution circuits including cables carrying electricity into homes, and substations. Magnetic fileds can also be produced naturally by some types of rocks, environment, and other anomalies.     According to the World Health Organization (WTO) Low-frequency electric fields influence the human body just as they influence any other material made up of charged particles. When electric fields act on conductive materials, they influence the distribution of electric charges at their surface. They cause current to flow through the body to the ground. Low-frequency magnetic fields induce circulating currents within the human body. The strength of these currents depends on the intensity of the outside magnetic field. If sufficiently large, these currents could cause stimulation of nerves and muscles or affect other biological processes.

  • Tests for the meat and fish from different sources shows x5 more nitrate then normal 200 mg/kg? Are the readings correct and what should I do with it?

    The EcoVisor uses the latest patented technology multi-point probe with temperature compensation and is calibrated against GOST 29270-95 “Methods of Nitrate Measurements”. This is the closest and the most accurate you can get for the portable express analysis of nitrates in products. The next step would be sending the samples to a laboratory and in order to compare the results (which we did when developed the product), you'll have to take the readings within 30 minutes between the lab and personal test, otherwise, the amount of nitrates can change.   Here are a few tips, that could help: 1. Make sure that you test only fresh (raw) products. It's not correct to test cooked meats or veggies. 2. When fresh produce or meats are affected by heat (cooked), most of the nitrates break down. However, the vitamins and nutritional benefits diminish as well. 3. It’s good to remember that a safe nitrate dose for adults is 200-300 mg/kg per day, while 600-700 mg/kg during 24 hours is considered high and can lead to a Nitrate poisoning. For example, if you eat fresh fish or meat (e.g. sashimi, carpaccio, tartar) and the Nitrate levels are 2000 mg/kg and you eat more than 150 grams (5 oz), there is a high risk of the Nitrate poisoning. For children, elders and people with a weak immune system, the recommended dose is even lower.

  • Is SOEKS nitrate tester usefull to identify whether fruit or vegetable are organic or not?

    It’s common that in conventional produce chemical fertilizers, such as nitrates, are used. SOEKS Nitrate Tester (EcoVisor) is the best tool to identify nitrates if fruits and vegetables. However, even in organic products it’s possible to find high levels of nitrates if the storage conditions were not satisfactory, or the nitrates came from other sources rather than the fertilizer (e.g. ground waters, rain, factories etc.)

  • Does the radiation detector click or beep when it receives a count like traditional GM devices?

    Yes, the Ecovisor F4 makes sound evertytime a charged particle hits the Geiger Muller tube, similar to a conventional Geiger Counter. It also alarms you if High levels of radiaiton are reached or the nuclear dose is exceeded.

  • Does it measure water pH?

    No, the EcoVisor works as a TSD tester, measuring Total Dissolved Solids, e.g. number of particles in the water besides the actual water. 

  • How often should the device be checked and/or recalibrated?

    The SOEKS EcoVisor comes factory calibrated and certified by the multiple external agencies. It doesn't require further calibration during the lifetime of the device.

  • Does the EcoVisor\'s TDS also have ATC (automatic temperature correction)? If not, what is the recommended temperature range to test at? I\'d like to use it to test not only drinking water quality (spring water, RO water), but also PPM for colloidal copper and silver, and herbal tea.

    The SOEKS Ecovisor F4 has an automatic temperature compensation correction built in in the multi-point probe. You can use the TDS meter function and the device will adjust itself automatically based on the temperature. It's a good idea to wait a few seconds until the temperature on the screen of EcoVisor is stabilized.

  • What is the range of radiation levels that this device accurately detects and reports?

    The SOEKS EcoVisor accurately detects ionizing radiation levels as low as 0.01 uSv/h up to extreme levels of 999 uSv/h. It can also show the results in Roentgens (mR/h) from 1 to 99999. It’s possible to set up tresholds on the device, so the alarm will sound when certain radiation levels are reached.

Soeks EcoVisor F4

I received my Soeks EcoVisor F4 Friday January 11, Saturday I tried it out first time testing my water in home ,tap water ,filtered water and purified water bought from local store , I was very impressed with how user friendly it was to operate first time and my “different “readings from each water sample I checked . I’m looking forward to using all my functions in soon time . Thank you Soeks ! Dave in Indiana

Sensor isceasy-peasy

Easy and intuitive to use. I started using it before reading directions. I have started tracking water wand food feom different parts of the USA. Only downside, I wish the battery life was longer.. Device is good for a high-level, quick testing for safe food, water, enf and radiation.

My unit

Stan I received the unit in about 3 days. It gives me peace of mind to keep on top of our changing world. I am a retired electrician. I wish I would have had the unit while I was in the field. The equipment and environment was always new and nobody knew back then about the dangers we were around. The unit is very easy to operate. Thanks you John Hill

I will use every function!

My favorite function is "all of them", although I would probably use the EMF function the most frequently. The addition of the dosimeter is a deal breaker! I will use every function because this device makes it so easy to learn how to use it. Because everything is contained in one device, I am also more likely to carry it with me and have the function I need at any time. I was also pleasantly surprised to learn that SOEKS will provide a software upgrade in the future to be able to download data to PC. The designers of this product did a wonderful job! KUDOS to them.
