Looks similar to the one they have on eBay.
I have one. Works great. No problems. Just calibrate every so often.
I think I paid $45 shipped.

 

[Dmitry]

How do you calibrate it??

 

[Savager]

I have it for few weeks now and it works great. I only calibrated once. It's worth it. I ordered with ground shipment, and I got it within 3 days.

[Dmitry]

That settles it then! I'm tired of using these manual ones with the floating arrow, etc. :irked:

 

[michael stern]

I use it, works great

 

[Reefer420]

same here - works great... calibrate it using distilled water (or RO/DI I'm assuming), you don't need any calibration solution or anything.

I had a few, but I find the "taste the salty finger" test to be best. Change enough water, and mix up enough batches, and you too will be a taste-bud guru

How do you calibrate it??

Distilled water.
Calibrate it back to zero & it's set.
