Ok gonna try this again! I know it may not be the best but it does show that all reading are within 1. You'll have have a tolerance no matter what. The temp sensor spec sheet reads that it can mearsure within 2.5 kpa that is app. +- 18mmhg and we are reading within .5 to 1 for pressure at mmhg(millimeters of mercury). You are not going to get any closer then that with any other instrument.
