[NLRS] piezoresistive transducers

[Curt Peterson]

Perhaps one of you electronic experts can help me. I am considering buying adigital barograph that uses a "piezoresistive transducer" to determine atmospheric pressure. The manufacture  -  Aquatech Scientific Instr.  LLC claims their barograph has an accuracy of +/- 0.25 mb (or =/- 0.007 " hg) atmospheric pressure. The Company seems legit. but the claimed accuracy is very high. Are piezoresistive transducers that good ? ? Please reply. Thanks.  KC0FQZ  Curt Peterson
