Jadenlea Posted September 17, 2015 Report Posted September 17, 2015 should I be storing it in a cup of distilled water so I dont have to calibrate it each time or SHOULD it hold its calibration for a little while Quote
JamesHe Posted September 17, 2015 Report Posted September 17, 2015 Never store in distilled water. You need store it in storage solution, which is 3Mol KCl solution. Quote
Shrimple minded Posted September 17, 2015 Report Posted September 17, 2015 I believe if it dries out it effectively loses its calibration. I reference the below for all things pH meter related. http://www.barrreport.com/forum/barr-report/articles-aa/11067-effective-use-and-care-of-ph-meters-and-probes Quote
JamesHe Posted September 17, 2015 Report Posted September 17, 2015 Distilled water will dilute probe reference liquid and response time will increase and reading would be unreliable. Keep the probe wet and store is in storage solution. Quote
Jadenlea Posted September 18, 2015 Author Report Posted September 18, 2015 just added this to my amazon cart but wanted to make sure its the right thing. Is this what you mean James? Thanks! http://www.amazon.com/Atlas-Scientific-pH-Storage-Solution/dp/B0071AR9XI/ref=sr_1_2?ie=UTF8&qid=1442538539&sr=8-2&keywords=Ph+meter+storage+solution Quote
JamesHe Posted September 18, 2015 Report Posted September 18, 2015 Yes, that's the correct one. You should check out the first comment. Q: what makes storage solution better than distilled water for storing pH electrodes A: pH probes should never be stored in distilled water; it will cause the salts inside the probe to leech out, rendering it useless. Either storage solution or a buffer solution should be used. Quote
Maurice Posted September 18, 2015 Report Posted September 18, 2015 Oh my goodness, I have been storing mine in RO water Is there any other solution that I can store it in except the storage solution as mentioned in the amazon link, as we dont get it around where I stay? RyeGuy411 1 Quote

You can store it in the pH 7 buffer solution. Maurice 1 Quote
Maurice Posted September 18, 2015 Report Posted September 18, 2015 Awesome thanks RyeGuy411 RyeGuy411 1 Quote
sarah Posted September 18, 2015 Report Posted September 18, 2015 In my lab, we keep it submerged in the pH7 buffer solution. Maurice and RyeGuy411 2 Quote
Maurice Posted September 19, 2015 Report Posted September 19, 2015 Thanks sarah, that is great to know! Quote
Jadenlea Posted September 19, 2015 Author Report Posted September 19, 2015 Ordered the storage solution before I saw the PH 7 thing . figures hehe. Quote
Soothing Shrimp Posted September 22, 2015 Report Posted September 22, 2015 yepper. That's how I ruined my Pinpoint ph probe. Quote
