It is very important to beep the probe in a buffer solution to void it drying out. Also a dry probe will make the auto calibration mode on a high end PH meter fail in some cases as the sensor itself not providing a signal strong enough for the meter to red. pH probes generate very low currents and millivolt levels so allowing the probe to dry out never a good idea. Of your probe is a wet probe it will have arrived inserted into a small pot with a rubber o ring seal. Review: Awesome product & Seller, exactly as described and shipped lightning fast as well. ## Features - Protective coverall CE Type 5 & 6 - For fine dust particles - Reduced spray and limited splash - 2 way zip front with storm flap - Elasticated cuffs, ankles, waist and hood ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01J5F1U3G | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 124,049 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 70 in Electrodes | | Customer Reviews | 4.6 4.6 out of 5 stars (156) | | Date First Available | 31 Dec. 2010 | | Included components | 500ml of storage solution | | Item Package Quantity | 1 | | Item Weight | 500 g | | Item model number | HI 70300L | | Manufacturer | HANNA INSTRUMENTS | | Material | PE_(Polyethylene), PLA_(Polylactic_Acid), Plastic | | Part number | HI70300L | | Product Dimensions | 127 x 127 x 127 cm; 500 g | ## Images ![HI-70300L pH Electrode Storage Solution, 500ml - Image 1](https://m.media-amazon.com/images/I/61wTUyxGBBL.jpg) ## Questions & Answers **Q: whats the difference between this and their GroLine storage solution?** A: I use Skunk Labs Potassium Chloride solution . it's cheaper **Q: After a few days, the solution becomes crystallized and chunky. What am I doing wrong?** A: Not sure. Mine lasted for weeks and only became crystallized of left uncapped or in the open air . Cld be bad to begin with if only a cpl days . Try gettin a refund or a new order and see what happens .. **Q: How much of this are we supposed to use on the ORP meter tip? Just pour some into the basin that the tip slides into?** A: Well Hanna says not to store the unit in that cap for what reason idk at least on my ph 55 meter but I use those packets it comes with to store it in and use just enuff to cover the electrode then change it once a week or so not sure what ph meter u have but you could most likely use the cap I used it on the last unit I owned so ur call **Q: This is probably an obvious answer but I thought I'd be careful; Can this storage solution be used for an Oakton pH meter? This is way cheaper.** A: I'm sure its universal just one thing when I used it, it got crusty on me so I just use ph 4 or 7 solution to store mine in and use the cleanin solution once a week on it is all but it would work for your meter if you wanna try it out for yourself and see. ## Customer Reviews ### ⭐⭐⭐⭐ Should use *by D***Y on 12 July 2023* I have a PH meter with a wet probe.

I use it after cleaning or during idle periods; soaking for an hour reactivates sluggish probes reliably.
