I won a Shuttle Portable "Ph Meter" in the Aurora auction. Now, what do I do with it? I hit the bid button and was expecting to get outbid, but I wasn't. I have to assume that NASA paid a lot more than I did for this when they originally purchased it. Any ideas on what it may have been used for? |

This NASA website describes in great detail the workings of the fuel cell power plants, including what the pH sensors were used for. (On the page, hit Control-F and search for "ph".) There might have been a pH sensor for other reasons, like onboard experiments, but this seems like a strong possibility. |

First guess it was used by technicians to test the water supply in the mid-deck prelauch. Water that is too acidic or basic is bad for health and the shuttle's plumbing as well.As to what do do with it — pH meters are handy to check pH's of: - Home water supply (check with your local government for water quality tests to see if they match what you get, if not you might need to get it calibrated or they are wrong)
- Fish Tanks (some fish are very pH sensitive)
- Swimming Pools
- Experiments in the Park - is acid rain affecting the local pond?
Have fun! |

In response to your first question... You are a collector. Never ask yourself that question! |
