TDS Meter suggestion needed

Another Marketing Gimmick is coming in name of TDS meter .... Relax , boil and filter tap water and drink without any worry 

The one from Xiaomi is good.

Am occasionally using this. Working fine

Aptechdeals TDS Meter/Digital Tds Meter with Temperature And Water Quality Measurement For Ro Purifier (TDS) https://amzn.eu/d/e...QV

thing with good reviews bro... dont think about these small things too much. all are good only. 

Planning to buy ro? Call ro local guy they bring the tds meter itself and tell them no if they offering higher price as compared to AZ/FK. 

IMO it’s used for only once to test tap water. 

I've been using Konvio Neer TDS meter for over a year now & it's readings are quite similar to the TDS meters the service guys bring with them during maintenance. It's a little expensive than your budget by ₹100 but it's worth it.

You are not going to get an accurate (calibrated) one in that budget.
