## Questions & Answers

**Q: Does this pen have the manafacturer's warranty?**
A: Yes. 1 yr on the pen and 6 mo on the electrode.

**Q: Why cant you store the probe in distilled water and is that any probe or just this one?**
A: Its for every probe and it's because it needs buffers in the water or it will draw them from the permeable bulb

**Q: Does the display have a back light? Its hard to read in low light.**
A: yes, i do have trouble reading.

**Q: What kind of batteries does this use?**
A: A stack of small watch batteries. I think the CR-4's. Not sure. I tossed this meter in the trash it sucked so bad. Bought an Oakton and have been much happier. The Hanna took nearly 10 minutes to give you a PH reading that was correct. Oakton meter takes maybe 15 seconds to give a perfect PH reading on a slow day.
