Edward, refering to the 2nd reading-humidity at 30% and temp at 38ºC, it was recorded in a hot morning but in a highland conditions where the air was still cooling. The 30% humidity will not stay constant but fluctuates according to weather conds.

ken, there are many brand with different prices. Lower price range usually have a margin of error ( refer to your booklet ). A small error like ± 2% was ok for home grown plants unless a requirement for precision.
