Abstract
A portable, hand-held fluid tester for testing and analyzing process fluids is provided with a volume controlled fluid reservoir. The test fluid reservoir is connected by a spillway to an overflow reservoir to provide more consistent and accurate fluid volumes for measurement. Improved mounting of electrodes in the test reservoir and connection to a testing printed circuit substrate provides for ease of assembly. A special temperature probe arrangement is also provided in a preferred embodiment.
