A first-rate gauge
I have had some occurrences of the fitting not sealing completely when attached to the valve stem, but removing the gauge, turning it about a quarter turn, and reconnecting it to the valve stem allowed the fitting to make a good seal, and I could still read the gauge easily (the hose is flexible enough to allow the gauge face to be turned so it can be read).
The company that manufactures and services the Accutire MS-5510B Tire Gauge has changed from the one mentioned in my original post (my 2nd gauge has the new company, Measurement Specialties, Inc.), but it seems to be a company at least comparable to the first one, specializing in pressure sensors, and they have contact info. printed with the gauge instructions.
After some months of use, I still feel this is the best gauge for the money and the easiest to use. Also, this gauge is now offered by Tire Rack and Proper Auto Care (both for more $ than it sells for here), which are two well-respected sites re high-quality automotive products.
Jan. 21 update: I got the low-battery indication while using the gauge, and it turns out that the LR1130 batteries are alkaline, not lithium as both the product packaging and instructions say they are. The batteries are indeed very easily replaced, and I’m replacing them with the silver oxide equivalent (SR1130W), as the original batteries apparently weren’t the freshest (although they were Hitachi-Maxell). I continue to like this gauge very much.
I think this is a great product at a great price (currently $35 total), and I just bought a 2nd one to lend so others can see for themselves (don’t want to be without mine in case it doesn’t come back).
Very simple to connect and take a reading, and when bleeding air the numbers drop with the drop in air pressure, so I can reach the exact pressure I want quickly. The batteries are user replaceable, but they are lithium (LR1130) and are expected to last more than several years (the packaging suggests they will last the life of the gauge, as “permanent power”). The gauge can be zeroed (recalibrated) simply by turning it on without any air pressure in the hose, confirming that the display reads “0.0,” and waiting until the display goes off (20 sec. when no pressure is present and 60 sec. when there is pressure present).
While the gauge display reads to a tenth of a pound, the actual stated accuracy in the instructions is plus or minus 1 percent plus 0.5 PSI, which suggests that the real accuracy is within about 0.2 to 0.8 pound, which is still better than any other gauge I’ve seen or used.
The instructions explain things well enough (they read as though they were translated into English, but still completely understandable), and the listed Web site for the actual manufacturer, Measurement Ltd., Inc. (in New Jersey), provides contact info. for user inquiries.
I like using this Accutire MS-5510B Tire Gauge (it’s quick and easy), and that makes maintaining my tire pressure at the proper level simple to do consistently (along with a good portable air compressor, like the TyphoonMax TX-500, which I also really like).
