Rated 4 out of 5 by from Verify accuracy Every one of these that I received has been out of tolerance, but they're simple to adjust and measure alright. Did the job just fine so far.

Rated 1 out of 5 by from Sensor Selection Tool Incorrect The online sensor selection tool doesn’t match the delivered sensor. This has happened twice in a row. We specify 0-1psi and get 0-1”WC.

I do not see a WEEE symbol on this device. Does it have the WEEE symbol if no can you add it? I can not buy/sell without proper compliance.

Asked by: Andrew at Caterpillar
