Compare the observed drift with the specified zero temperature coefficient before suspecting sensor failure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: What information should buyers provide when sourcing a replacement Baratron gauge?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eProvide the complete model code, full-scale range, fitting type, connector type, output signal and supply voltage. Also confirm wetted materials and process gas compatibility.
