hi peeps i have the hannah HI 98103 and i dont know if its just mine but it seems **** lol, ive calabirated it twice, change the batteries, but it just takes forever to stabilise, am i doin something wrong, i put it in whatever i want to test (egg white) and it went from 7.01 - 7.25 really slowly and just wouldnt stay on a number for long before going down or up, should i just get PH strips instead ?
Call the company, they're very good about working with people and will replace parts and even the entire Hanna if it's bad.
i brought this new off ebay, with this hannah do you have to swirl the probe in the sample to get the reading ?
I have this exact problem with my HI99104 hanna tester. I called the company in Australia and they said it probably needs to be cleaned properly in the cleaning solution (which I don't have) or there is something wrong with the electrode and may need to be replaced. All very irritating when I'm due to ovulate tomorrow... grrrr...
oh no thats a nightmare, ok i was told that distilled water can clean them well, just leave it to soak for an hour in there swirling it round every 10 mins, does yours have to be swirled around in the sample whilst you take your reading ?
Even if you've bought it off eBay, sometimes the company will help you get it figured out.
ok thanks il try them,
