I have used the meters of different brands . Such as chines, Korean Tywan etc. But all are baseless. The result of this meters are not satisfactory . After experiment for a long time I
have selected and tested a Meter( from USA). The result is very very fruitful . Any body can compare the result with the pathology Lab . I am highly satisfied with this meter . If any body can test the Meter, he may contact with the distributor of the company as KALYANI ENGINEARS mOBILE : +9830801191.
