SKS Airchecker Air Pressure Gauge with Dual Head

This is a good buy - especially if you check tyres with both Shrader and Presta valves. Easy to work. Adjustable head is a great innovation n tight spots (e.g., bike spokes). Does tend to auto-shutoff quickly, but otherwise works well and is very accurate.

perfect for my mtb bike where I need to fine tune the psi!

I wanted this to get more accurate pressures for my gravel and MTB: my old track pump gauge goes up to 160 psi so was difficult to fine-tune pressures below 30 psi.The Airchecker had great reviews so I ordered it. But when it arrived it showed much, much lower pressures than the track pump that I e been using for 15 years: on my gravel bike it read 25.4 psi but track pump read ~35. Then on my road tyres it read only 42.5 psi, despite 80 psi on the track pump! I was worried: was my track pump actually overestimating pressures by 40-90%?? Or was the Airchecker actually rubbish?One other review said it can be inaccurate on first use and suggested to remove and then reinsert the battery. I did this: still no agreement between this and my pump. I then went to my local bike shop to test it against their pump (Zefal pump in the attached photos). This showed very close agreement with the 25.4 psi measured by the Airchecker (and I also validated it for several higher pressures). I’ve since bought a TopPeak Jow Blow pump that also agrees with the Airchecker.So, the good news is that the Airchecker is accurate. It’s really good at fine-tuning pressures for off-road riding. And small enough to take with you on rides (in case you want to test the real-world effects of different pressures).The bad news is that I’ve been running tyres at 50-60% of intended pressure for who knows how long 😱! Maybe the silver lining is I’ll be much faster now?Lesson learned: don’t always trust your track pump. I wish I bought one of these a few years ago…

This product did not seem to have any detractors when I checked the reviews so I felt safe to buy it, but it managed to let air out when I tried to use it. I will soldier on, as I may have been cack handed. There does seem to be a problem with some 'fits-all' connectors so thought this with two separate ones would be better. As I said a nice product, I like way it lights up so it is easier to read. I hope I can get the knack off using it without deflating what I am testing!Ok further trials and still not working, it can fit without leaking air but no reading appears just Zero zero! Maybe mine is faulty but it's not working for me!

Measures within a couple of psi of my Topeak Joe Blow Sport track pump. Feels a bit cheap and plastic but it’s sturdy and is holding up well so far. Only used on Presta valves and the seal is tight with little to no air leak when you first attach it. For comparison, my Topeak Smart Gauge D2 is a bit hit and miss when initially attaching to the valve resulting in air loss. The SKS Airchecker is more reliable.

Very good for the price. Air release could be a little better.

Very good build quality. Accurate. Portable and light. Easy to use on my motorbike( can be used on cars and bicycles as well). Good seal with valve. Really impressed. Considering ordering a second one to carry in my bicycle saddle bag(that’s how light it is)

Nice little unit, both types of valve fittings. Lightweight. Has a backlight on display which is handy.
