Indicators in the «Measure» mode
A screen with the following elements appears in the measure mode:
8. Measuring result.
9. Unit of measure: mg/kg.
10. Result message showing nitrate concentration based on maximum daily
rates of nitrate consumption with food.
- if the measured result of nitrate concentration does not exceed the medium
norm of nitrate consumtion - you will see the following message marked
green «Normal nitrate concentration».
- if the measured result of nitrate concentration exceeds the medium norm of
nitrate consumption not more than 20% - you will see the following message
marked yellow «Insignificant excess of standart!»
- if the measured result of nitrate concentration exceeds the medium norm of
nitrate consumption not more than 50% - you will see the following message
marked red «Significant excess of standart!»
- if the measured result of nitrate concentration exceeds the medium norm of
nitrate consumption more than 50% - you will see the following message
marked red «Dangerous concentration of nitrates!»
11. Coloured indicator.

Remember that the result obtained is an estimate, and it cannot
replace a quantitative chemical analysis in a specialist chemical laboratory,
which is not free of charge and requires time. However, the presence of such
laboratory and a qualified chemist/analyst at home or in the pocket during
each purchase of fruit, vegetables or berries is impossible for the majority of
people, while the presence of nitrat-tester Soeks allows one to refuse the
purchase of suspicious foodstuff, and to significantly secure oneself and
relatives, especially children. Such analysis made using nitrat-tester Soeks is
performed in a few seconds, and the only thing the device needs for a
long-term operation is that you do not to forget to change the batteries or to
recharge accumulators as a usual cellular telephone.
Certainly, the question may always arise: what if excessive
electric conductivity of a foodstuff is due not to nitrate ions? Such situation
is possible, but will the buyer feel easier if he or she has bought a foodstuff
with an increased phosphate (or other ion) content instead of nitrates or
simply a foodstuff that started to spoil? Remember that base electric conduc-
tivity was determined for each individual type of fresh fruit and vegetables
while the composition and concentration of organic acids vary during rotting.
