They are said to come calibrated for saline solutions, but your water will only be saline in part. The two I have are adjustable by a trimmer accessed via a hole in the rear of the casing. It was found possible to recalibrate one to WallyBrews findings in a sample of the same water I kept for this purpose. Accordingly I was able to take a TDS measurement in a few seconds this morning and then quickly interpolate between tests he did to determine the content of all major ions including alkalinity in my water.
Even if that version isn't adjustable it will quickly advise if your water has changed by whatever reading it gives.
Without patience, life becomes difficult and the sooner it's finished, the better.

Or would I be better spending more money on something like this?

PS, Thanks for all the advice I am getting...

The cheap one proved suitable for my purpose, so much so that I bought a spare. A sample of one water tested by WallyBrew is kept safely should it be thought necessary to recalibrate an instruments.
I suppose using electrical conductivity would be more logical, but using the summation of all major ions for brewing fits comfortably for this purpose.

Hi guys,
Just an update to my water analysis. Ive just tested my water with the Calcium test kit. Low and behold its low.
So far the water is:
Ca = 20ppm
kH = 0.1meq/l (5 CaCO3)
TDS = 49 ppm
pH = 5.2
I have mailed WallyBrew for a water test but this can't be done for a few weeks. Will be good to get the full water results from him.
What do you think to the water - as per brewing liquor it seems pretty useless.

Re: Salifert KH + Alkalinity Profi-Test Kit
It's very similar to my water,and my beers are not bad. It does require treating. I use calcium chloride and gypsum to take the calcium level up to 75 to 100 ppm aiming for a sulphate to chloride ratio of 2.5 to 1 (hoppy) to 1 to 2.5 (malty) . . . Dark beers I add potassium bicarbonate to take the alkalinity up to a maximum of 125.
