The best thing about the digital is that it's not colour in a solution or the tabs that change colour, especially for a molasses wash it is great.
This is a ebay link to the one I a using, there are plenty cheaper available, I was just impatient and bought it at the local pet store. http://www.ebay.com.au/itm/AQUA-ONE-PH- ... 52b&_uhb=1

Yes, I was just talking to an expert on these today. The ultra cheap ones like mine do have a limited life but its the same old story, treat it good and it will last longer. I then purchased 2bottles of pH buffer and a storage solution. Each were 250ml and the lot cost about 25 bucks.
