In the past I have owned a couple gauges that looked like the one you posted, and they all started to leak or give incorrect readings after a fairly short time. They would either leak around the pressure release button or from the seam where the chuck tip itself swivels. I also had one where the gauge itself started to display wrong readings. The mechanicals of the gauge just couldn't handle the rapid up/down pressure changes for very long. There might be some good ones out there, but I personally won't be buying any gauges made that way again.
You might want to look into tire pressure gauges used for bicycles for more options. Thin road style tires often get pumped up into the 80-130psi range, so there are pocket sized mechanical pressure gauges for them which go up to 150-200psi max. Most aren't heavy duty, because they are usually designed more as lightweight easily carried occasional use tools, but I'm sure there are some high quality options out there.
For quick/simple pressure checks I carry around a Milton 925 (20-120psi) slider type gauge. The body and head is metal and it's about the size of a Sharpie pen. At the higher pressure ranges where I use it, mine is always accurate within a psi or two when compared to my mechanical test gauges. They sell the same gauge with two styles of dual head tips as well if that's something you would prefer. For passenger vehicle tires or other air pressures below about 40psi I personally use a Milton 921 (5-50psi) gauge instead.
A better set up for higher pressures and constant use would be something like a Milton dual head service gauge, which can be easily re-calibrated yourself if necessary, and it's design will work better for things like dually tires. It is pocketable, but the pocket would probably need to be 9-10" deep for it to carry well without wanting to fall out.
I don't have that particular Milton dual head model, but I do have two vintage Schrader brand pressure testers that operate in the same manner (a "Service Tire Gauge" and a "Trutest Special"). They are my primary use gauges when testing higher pressures. They both measure air pressures up to 160psi, and they are accurate at car tire pressures as well (34psi or so). My Trutest special gauge is only 12" long, so it can ride sticking out of a jean or overall pocket without issue. I wear painter's jeans a lot, and the side pocket they usually have on the outside of the right thigh also works great for holding a tire gauge of this style. In my experience, good quality slider gauges are usually very accurate and also incredibly durable over time compared to mechanical dial style or digital gauge setups.
If you want to DIY your own high pressure gauge out of quality parts, you could do something similar to what I did when making myself a couple mechanical gauges for measuring lower pressures. Buy or re-purpose a good quality mechanical gauge that goes to 200psi or so and then thread a 1/4" npt female quick coupler onto the stem. Then put any of your regular air chucks onto the end of the quick coupler as needed to test tire pressures. Use a stubby air chuck and the whole setup would fit in a pocket no problem. The only potential drawback to my DIY setup is that it only displays the tire pressure while the gauge is being pressed on the valve stem. Remove the gauge and the displayed pressure goes to zero automatically. I actually prefer it that way, but it might be an issue for anyone who needs to test pressures in a location where you can't read the gauge until you after you remove the tester from the valve stem.
Good luck.
