My junior high's team has been having difficulties with their conductivity testers (they have both a digital and a low-tech LED one); both are saying that ordinary distilled water has "very high" conductivity. They tried recalibrating them, but it didn't seem to make a difference. Does anyone know what might be the problem?

Distilled water... well, ours is showing that it has no conductivity... that's a weird problem..

@CJAP Crazy: do you mean testers? xD or tests? for testers, if you search conductivity tester, they won't all show up as 'conductivity tester'. you'll have to click on each one and read the description, because some are both pH and conductivity testers.

You don't need practice tests to practice for Can't Judge. Just choose a powder and use all your chemicals and practice often.

True, but you also need to know some general chemistry. I've gotton questions on that, and if I hadn't studied chemistry, I would've done worse...
