Digital Low Pressure Gauge with 1/4'' NPT Bottom Connector and Rubber Protector, Range to 15 psi, Accuracy 1% .F.S.

Es perfecto para lo que necesitaba. Medir presión de aire en tubería.

Works good so far. Does what its supposed to do.

I use it for pumping up SUP boards and the meter gives a very accurate representation of the air pressure with a sensible scape.

My original analogue guage was totally useless. It used to read up or down. Never anywhere near the correct pressures. I calibrated it and it lasted 1 use before going out again. I saw this one in Amazon for cheaper than most analogue pumps so gave it a try. It comes in a nice box with instructions. I removed the old analogue guage and binned it, then screwed in this new digital guage. Remember to use PTFE tape on the threads and if the guage doesn't sit where you want it when it's tight, use more PTFE tape. Never overtighten anything to do air compressors as the parts are prone to cracking. Inserted batteries and the unit came on right away. I blew up an old spare wheel to 36 psi (see video, bad quality but I'm stuck in the corner of the garage holding the phone and blowing up a tyre, so deal with it). I then put a calibrated digital guage and a calibrated analogue guage and both read the same within a few decimal points, which is to be expected as you'll always lose some air when you connect to the tyre valve. Overall I'm really happy with my purchase and I think it's a great price too.
