Review on High Precision Stainless Pressure Gauge for Compressor Hydraulic Testing and Inspection by Zach Flores

I have been using this as a pool filter gauge and from the description I thought it would be my last gauge purchase. Temperatures of -30F are very cold and, believe it or not, colder than Minneapolis. Bought June 2020. Closed for the pool in winter. The pool will open in Spring 2021 and the new zero is 40psi. The pressure gauge does not correspond to the specified operating temperatures. A 90-day guarantee isn't much. Other observations: no external corrosion visible after 1 year of operation. The sensor looks as new as the day it was delivered.
