    Good Product at great price
  

*by A***R on Reviewed in India on 10 February 2019*

Good product for measuring EC of water. Accuracy is enough for rough measurements. Haven't cross checked yet. Anyway, I got it for less than 600, which is a great price as well.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    EC reading doubtful
  

*by D***A on Reviewed in India on 4 December 2019*

Got this product yesterday. I bought it mainly for EC. Though TDS of water shown is correct but corresponding EC value is in hundreds which should be in decimals. The decimal is missing in the reading. Can company clarify this?
