🔧 Tru-Flate 17-521 Low Pressure Tire Gauge: Ideal for Garden Tractors, Golf Carts, ATVs & More Review

A great way to check tank pressure for reverse osmosis water treatment systems. A regular "tire" sensor simply can't measure pressures up to 7psi. In spring I will use John Deere X500 tires.

Used this gauge for the first time today to inflate ATV tires to 7 lbs. Measurements ranged from 7 pounds to just over 8 pounds when measured multiple times per tire, so I think my error was in the 1 pound range. The caliber was only around $8-9, and the 7-8 pound gauge was just right for my needs.

I bought this for my garden tractor tires which were supposed to be 14 and 10psi. As you may know, most analog gauges are less accurate at the lower end of the scale, so your standard 60-80 psi gauge may not give an accurate reading at low pressures. This fills that gap. It appears to be of a sufficiently high quality and I have no reason to doubt its accuracy. If you have low pressure applications I recommend this gauge.

Bought to measure the pressure when filling the water tank of my reverse osmosis system with air. To ensure the pressure, I bought two pressure gauges. You read 7psi and 7.5psi. I thought these readings were very close, so I believe the sensors are very accurate. With pressure gauges, it was easy to fix the slow water supply to my reverse osmosis system (except for the pressure gauge) quickly and for free. I can recommend this clinical thermometer.

I bought it to measure fat bike tire pressure. I like the idea of not being battery dependent like digital sensors. And these skinny fellows are easy to hide in my tiny bike tool bag. I don't know how accurate they are as my 1 or 2 psi seems to be registering more than it should. But it's pretty consistent, so I can take that into account. You have to hold it up properly, which is sometimes difficult with gloves on in freezing weather; but I assume every sensor requires it.

Hard to read. The numbers are next to the dots, but upon re-examination, it turns out that the lines indicate full psi. The dots are intermediate marks. Why put an integer next to intermediate marks? Bad design. On top of that, it's still the best and most accurate low pressure gauge I've used to date, and I've used it a lot. Just recently I bought a much more expensive battery and the thing was complete bullshit compared to this one. It was new out of the box. In short, it will work for many…
