AstroAI Digital Tyre Inflator with Pressure Gauge, 0.1 Display Resolution 250 PSI Air Chuck and Compressor Accessories Heavy Duty with Rubber Hose and Quick Connect Coupler

This is a great edition Tommy compressor. Purchased to replace my analogue gauge. Works well and have checked it’s accurate with my other gauges. Results are consistently accurate and similar to my other tools.

Found the gauge to be very sensitive and quite accurate

This arrived as promised and was impressive right from opening the box. once the initial problems were resolved it proved to be accurate and easy to use. It feels like a reliable and well put together product apart from 2 initial problems. When used for the first time the connection to the valve leaked. 2 reasons for this were identified. The first as that the connection from the handset output to the output hose was loose but easily tightened. The second was more troublesome as the connection to the valve leaked an every one of the 8 tyres I tried and this seemed to be a combination of 2 causes. The blade, for want of a better word, which should grip on the valve thread to hold the connection in place is in fact 2 blades and as such is too thick to grip on the thread and the other problem seems to be that the connection seems to seal only when it is pushed to the end of the valve thread. I solved the problem by using an extention with a valve thread on one end and a valve connector on the other. I managed to get a good seal on the input end of the extention and the other end had a traditional lever and worked perfectly so I now have a inflator and pressure gauge which agrees perfectly with the pressures reported by the pressure monitoring sustem. I wonder now if this was a manufacturing error and this item may have been returned as faulty.Otherwise, I am now delighted with my purchase although others would have complained and returned it.

Item arrived on time and as described and works well, plus value for money for amateur use! Only one negative it came with a 1/2inch BSP fitting so I had to purchase separately a 1/4inch fitting

Great piece of kit Great piece of kit and so easy to use.

Excellent, sturdy and well made, does the job, clear display and at the price value for money.Simple to change between displays, just press the button.Display is also illuminted so easy to read in darkness.

As advertised seems good quality

I use this on a Ryobi portable air compressor for car and bike tyres. I’m a bit of a tyre obsessive as I look after a few cars of my own, with summer and winter tyres, and have bikes running tubeless tyres which need higher air volume and flow speed to inflate and set up tubeless but use a different valve type.Previously I’d used a mixture of bike track pumps for bikes and cars, and plug-in 12v compressors for cars, all with analogue gauges, and used a digital gauge to finalize and check.Having had the compressor a couple of years I’d already fitted an analogue dial-type air gun trigger and swapped out the connector for a bike-type twin-head design with both schrader and presta fittings, but with the inaccuracy and finicky nature of needle dial gauges I was always checking with a separate digital gauge after inflating. Those are usually in 0.5psi increments for accuracy but easier to read than a dial.This gauge reads to 0.1 psi and can switch between Psi, Bar, Kpa Kg’/cm etc. so it saves having to work that out, since cars often have different units stated.The thumb-lever valve head isn’t great if you ask me, it’s a bit hit and miss unless you use it a lot and get used to it, letting out air if you don’t get it right, so the twin-head bike type valve head I bought separately works better for me having a more consistent and secure engagement.This unit with its digital dial is much easier to read and lights up if required as well.The only downside with this is that I’ve twice punched my skin and drawn blood while handling the trigger head. This might be due to the slightly longer lever than my previous analogue trigger making it easier to depress while handling, I don’t know, the design looks the same except for the lever length as my old dial-type trigger handle. I think it pinches between the lever and the trigger valve ‘piston’ just behind it, so just be aware of this when you start using it.
