MEASUREMAN 3-1/8" Dial Size, Digital Pressure Gauge, 0-100psi/bar/Mpa/Kpa, 1/4" NPT Lower Mount, 0.25% Accuracy

These are a very cheap alternative to the other brands and work just as well! I’ve check checked accuracy along side liquid filled gauges and they have been spot on!

Needed high pressure gauge and this one fit perfectly. Reading the pressure from a distance is good and it has a light also.

Works as expected for pressure measurement. Little bit slow to respond to pressure fluctuations.

I got to use my new digital gauge today and have to say, I love it.It is so nice to switch in between the various units like PSI, bar, kpa and Mpa.You always have to give it a little time to get adjusted to the pressure. But I have found that to be the case on any digital measuring device. The electronic takes time to adapt and calculate.I unintentionally left it on over night, but no problem.Now I can retire my collection of analog gauges and won't blow up a 600 PSI gauge anymore, because my pressure accidentally went over a thousand.

This is a really nice precision gauge, that works well and so far seems reliable. But until I had it in hand, I didn't really appreciate how bigt this thing really is. Including the protective rubber boot it is over 3 1/2" in dimameter, over 2" thick, and over 5" tall (including the fitting at the bottom).I have no better gauge against which to check accuracy, so for now accept the accuracy spec as stated.But I have 2 issues with this unit:1. It responds *very* slowly. It takes more than 15 seconds to get a stable pressure reading when given a pressure step. That makes it excessively slow to use for fine pressure adjustments. That's fine if all you need is an accurate reading of a stable pressure, but if you need to quickly adjust pressure very accurately you should probably pick a different gauge.2. Changing batteries is a PITA. The battery compartment is on the back of the unit, covered by both a large round metal cover (secured with 3 screws) and the rubber protective boot. So to change batteries you'll typically need to dismount the unit, remove the boot, unscrew the cover (being careful not to lose the screws), change the batteries, re-install the cover (noting that the screw pattern is not symmetrical, so you have to orient it properly even though "top" isn't marked), re-install the protective boot, then re-mount the gauge. That's a LOT more work than it ought to be.I've modified the boots on both of my units as shown in the photo. On one I opened up nearly the entire back of the boot to allow removing & re-installing the metal cover plate without removing the boot. On the other I've permanently removed the metal cover, and cut a rectangular opening just large enough to easily remove & install batteries. The latter would not be acceptable in a high-vibration environment. I see no justification whatever for making what ought to be a very simple battery replacement operation so absurdly difficult. The battery compartment ought to be covered with a snap-open or single-screw cover accessible with the boot in place.But other than the slow response and the battery compartment stupidity, I really like this gauge -- enough so that I've bought two, and wouldn't hesitate to buy more for applications that can live with the slow response.
