Review on 🔒 MEASUREMAN Pressure Connector Protective, 0-200 PSI: Enhanced SEO-friendly Name by Ashutosh Takumatla

I was looking forward to using this instrument but found the barometric pressure readings differed by about 5psi. Another reviewer mentions a calibration method. If I did that Trying this procedure my meter stops and never gives a 'pass' notification.After that it freezes and shows '00'.I have to remove and replace the batteries to restore normal operation.There doesn't appear to be any support for this in the product The "Measureman" brand name seems to only exist as a Revain product line. I was hoping to find a website with instructions explaining if and how the gauge can be calibrated. It's a shame because the measurement seems to be very accurate , as shown by the reproducibility of serial readings, although the quoted psi is wildly inaccurate, worth a try but I don't want a meter that the PSI I want to control is almost 20% off the expected accuracy. A simple calibration procedure would be useful and would make this meter very valuable, but in its current state I would say that despite its reasonable price the meter is worth very little.
