GreenTest (2018)

In January 2018, food safety company, Alvarita, launched the world’s first portable nitrate and radiation detector in South Africa. GreenTest is a compact, award-wining, device that tests nitrate levels in fruit, vegetables, meat, and water, helping people to quantify their daily nitrate intake and make healthier choices. The food safe nitrate levels are determined on the bases of World Health Organisation (WHO) standards.
