if your using a road bike, tire pressure on road bike goes upo as high as 120psi, but on MTB maybe 50-60psi, I will not be able to recommend any tire pressure guage, but I am using Silca floor pump and it has an air pressure guage and I foind that they are almost close to the accurate thing, so hand held air pressure guages, can't exactly give you the result you want, You might try using this floor pump with the guage..
