Hello. I've already received a request (hi, Alex!) to post the info on the inexpensive Hanna TDS meter I recently purchased. I'll have to wait to see my own post on the Digest version!
http://www.hannainst.com When the opening Home Page opens, click on "Special Promotions", then click on "USA" (or Canada for you north-of-the-border folks), then click on "TDS Tester". The Model TDS1 instrument I bought is at the top of the page, for $14.90. It's made in Portugal, completely plastic with a small LCD display at the top and a tube at the bottom you insert into the solution. 2" insertion is recommended. I tried it once with mine in only about 3/4" and it didn't read the same as with 2" insertion--so you need some sort of small container with at least 2" of solution for best readings.It runs on some Lithium watch-type batteries and is supposed to last for quite awhile, according to the literature. One packet of calibrated solution comes with the instrument. You can buy a whole box of calibrated solution packets also, for $25. A calibration sheet comes with each instrument, with a real technician's results and initials. For $14.90 you would hardly think the company could afford to actually calibrate each individual unit! When I ordered mine I was informed they had two models, for the same price--one with an additional temperature readout plus TDS, or the plain TDS model. I ordered the combo unit. As they asked for my phone number when I ordered, I received a call from them several minutes later saying all the combo units were out of stock, would I like a plan TDS unit, or wait for more to arrive in shipment. I went with the plain version, just to have one "right now". As the TDS meter is internally temperature compensated I decided I really didn't need the added temp function, for my own CS generating. I must say that dealing with this company has been a most pleasurable experience. I emailed them initially to ask if the "promotion" offer was still in effect. Someone actually called me the next day to say the promo offer was valid, plus someone emailed me with the same information, within 24 hours. When I actually ordered, the person was very friendly. I have rarely emailed a company with a question and gotten any sort of response under 7 days, if at all, and never had them call me. This company appears to be a good one to patronize, at least judging from my "customer service" experiences. Steve -- The silver-list is a moderated forum for discussion of colloidal silver.
