Product Description

Guard Your Health

How healthy are your fresh fruit and vegetables?
Fertilizers that contain necessary elements for plant growth are used for cultivating fruits and vegetables. However, misuse of production technology, usage of prohibited fertilizers, pesticides and chemicals, as well as an increased level of fertilizer concentrations in the soil can all result in a serious damage to your health. Of all the substances that are transferred to the soil from fertilizers, nitrates are one of the most harmful if consumed in excess. Continuous intake of food with a high nitrate content may lead to an elevated risk of serious diseases.
Are you being exposed to dangerous agricultural chemicals? Many farmers apply too much fertilizer. This can result in unsafe levels of fruit nitrate and vegetable nitrate content. It's especially dangerous to children.


Nitrates and nitrites in fruit and vegetables: The risk to human health
Most health conscious people know about the dangers of pesticides in fresh fruit and vegetables. Few are aware that fresh fruit and vegetables expose them to dangerous nitrates.
Due to lack of regulations and consumer awareness, nitrates in fresh fruit and vegetables pose a greater threat than pesticides.


Nitrates cause serious disease
It has long been established that excessive nitrates are harmful to health.
Excessive nitrate consumption causes blue baby syndrome and adult methemoglobinemia. Nitrates significantly increase the risk of diabetes, Alzheimer's and Parkinson's disease and certain types of cancer.
Some researchers believe that the dramatic rise in cancer of the esophagus recorded over recent decades can be attributed to excessive nitrates in fruit and vegetables.

Nitrate content in fresh produce is unregulated
Due to the dangers, most jurisdictions tightly control the nitrate content of meat products. Food producers who add nitrates to meat must comply with strict regulations and labelling requirements.

Unfortunately nitrate levels in fresh fruit and vegetables are unregulated and unchecked in most places. There are no standards for producers or labelling requirements for sellers.

This is a risk factor. Improper farming and storage methods can result in excessive nitrate content in fruit and vegetables. Because there is no testing for nitrate levels at any point in the supply chain, consumers of fresh fruit and vegetables are exposed to unnecessary danger.

Healthy eaters are most at risk
No food is ever completely safe. Even fresh fruit and vegetables can make people sick from contamination from bacteria, pesticides and other residues.
Consumers are largely protected from these risks by testing and regulatory oversight. However they are not protected from excessive nitrate content in fresh fruit and vegetables. There is no oversight.
Because of this negligence, health conscious people who who eat healthy amounts of raw and lightly cooked fresh fruit and vegetables have a greater risk of consuming harmful nitrates.

More dangerous than pesticides?
People seeking healthier food often choose produce that's grown organically without pesticides and herbicides. But that organic label can provide a false sense of security.
Fruit and vegetables certified organic may still contain high levels of nitrates, absorbed from over application of natural fertilizers such as manure. So while avoiding harmful inorganic contaminants the consumer may be exposed to unsafe nitrate levels.
Currently the only way to know fruit and vegetables are completely safe is by analyzing the nitrate content of the food you eat.
Nitrate levels in fruit and vegetables can now be measured quickly, easily, and accurately with Greentest, the portable nitrate detector by our company.

GREENTEST-Always On Green Side

There Is A Difference

Our company dedicates ourselves to changing the quality of life and protecting us and our children from the infringement of harmful impurities, nitrates and nitrites. As a result, a revolutionary new food safety testing device Greentest, has been developed, which allows detecting fruits and vegetables cultivated improperly and evaluating the concentration of nitrates. It helps us satisfy our "greenlife" desires to rub the lamp.

Now you can identify unhealthy fruit and vegetables with this portable fruit and vegetable nitrate tester

  • Protect yourself and protect your family
  • Simply insert the probe into your sample
  • Easy-to-read test results in just 3 seconds

GREENTEST-A scientific approach to food safety

Greentest works by measuring the electrical conductivity of the fruit or vegetable matter being tested.

Lower resistance = higher nitrate content

The presence of nitrate ions in organic matter measurably increases conductivity. This measurement differs according to the ion concentration and cell structure of the fruit or vegetable under test.

Calibrated through extensive testing

Our scientists developed the Greentest nitrate content protocols by using a mass spectrometer to determine nitrate levels in a large number of fruit and vegetable specimens.

Testing a range of specimens under laboratory conditions allowed us to establish normative levels for various fruit and vegetable species.

A high degree of accuracy

The results were applied to test algorithms which have been coded into the Greentest device. The device has been extensively back-checked against specimens that were subsequently tested with a mass spectrometer.

The device is certified to be more than 90% accurate according to third party testing.

This is more than sufficient to produce a valid assessment of nitrate content.

GREENTEST-How It Works

THIS THING WORKS AND IS NOW NEXT TO MY FRIDGE HANDY SO I CAN EAT SAFER!

THIS THING WORKS AND IS NOW NEXT TO MY FRIDGE HANDY SO I CAN EAT SAFER!
So I had a bunch of old fruit in my fridge because I wasn't feeling well so it didn't get eaten. Let's see I had Cherries, Nectarine, Watermelon and an Orange. I didn't test the orange not sure why. Anyways, in my opinion it works I mean I knew this fruit needed to be tossed and I did just that after testing. I was sure to wash the probe tip each time between each fruit..what's interesting is the order of the strength of nitrates because the Nectarine was the oldest piece of fruit and it had the highest content warning me in red the content was 480..wow. Then I had bought the cherries a few weeks ago and you can see they are at 130 and then the watermelon I had sitting in the fridge for about 10 days and it was at 120. It wasn't a very sweet one I let someone else pick it and I didn't like it so it never got eaten..very sad about that. I have another one sitting on the pantry floor..hopefully it will be sweeter. Anyways in my truthful estimation it works. I didn't charge it or anything just held down the power button straight out of the box and was good to go. I didn't have any veggies to test since I always buy just sweet frozen corn and peas but, I have no doubt in my mind this thing is accurate or at least close to say hey that stuff is rotten throw it out! :D lol I kind of want to test it at the store but I don't think the produce guy would think that was a good idea. lol Although, you know how they cut up and make those fruit tubs..this would be a great thing for them to have prior to cutting up fruit that may not be as fresh as the other stuff. I received mine as a complementary sample in return for my testing and feedback on it. I'd say my test is conclusive no matter what the girl who says it's a scam says..she's full of it proof is in the rotten fruit! Hehehe Thanks and have a great day! Peace!, ~Kiki

The cover would not go in until I glued the two pieces together. See photo. Update, my msg to the seller: My unit has no hole in the lid. The cover comes off when I have it in my pocket. This hearly caused me injury. I do not accepet your $20 offer. This device has great potential for health of our patients. I need you to send a replacement and a postage-free return label for this defective unit. edut/update seller fixed the issue. this is a important device for our patient group.
we discovered that kirklund bottled water has 21X the nitrates of our municipal tap water. that bottled water is 2X the legal limiti. also corporate suprmarket dimsum has 2x nitrates compared to a local chinese bakery. updated rating
