I bought an Expedition analyzer in Feb. 2003 and I'm currently on my fifth or sixth sensor (which currently hasn't read above 11% since January 08, I've just been financially reluctant to replace it).
My first two sensors were black and all of the last ones were white. While the white ones have been better, 15 months is the best they've done so far (the original black one lasted a month and you swapped it under warranty).
What am I doing wrong or is this the expected life span of the sensors? I store the analyzer in it's box at room temp (77-78) and moderate humidity (50-70%).
