TDS readings

What TDS levels are you all getting from tap water? I'm getting 8 ppm from my tap water and 0 ppm after going through the RO. Wondering if this is accurate or if I need to calibrate my meter.

88 before 0-1 after. It will vary from town to town

But I would very surprise any town could have water as low as 8 ppm

I thought the thing had a decimal point in the reading, but that must have been a spec on my glasses... :D

Mines 171 out of the tap today. Yucky hard water. :(

I get 17ppm befor and 0 after.. in the spring my TDS goes as high as 20ppm so you could have 8 ppm but I would get some one else to test it to be sure.

Sam, I get 14ppm out of my tap, 1 ppm exiting my RO and 0 ppm after my DI.

<font size="2" face="Verdana, Helvetica, sans-serif">Thanks Stephane. Yes, it will vary from town to town. I actually forgot to mention that I was originally interested to hear what people in Vancouver and the Lower Mainland were getting. Although it would be also interesting to see what other cities got.

Thanks all. Canadawest, yes, I remember you said something in the 10's before but couldn't find the reference now. I saw on Usenet that Reefburnaby was getting 14 also.

'"Dissolved solids" refer to any minerals, salts, metals, cations or anions dissolved in water. This includes anything present in water other than the pure water (H20) molecule and suspended solids. Suspended solids are any particles/substances that are neither dissolved nor settled in the water, such as wood pulp.'

Darn. I just recalibrated twice with 800 ppm calibration fluid, adjusting for current temperature, and I'm now getting a TDS reading of 2 for tap water.

OK, so I could have elaborated a bit [img]tongue.gif[/img]
