This gauge functions through a 'double-bridge' smart-chip microprocessor that controls accuracy--compensating for ambient temperatures, humidity and altitude variations.
Spotlight customer reviews:
Customer Rating: Summary: DO NOT BUY Comment: My experience with this item is that it's great when it works, but it stops working very quickly. I purchased one from Roadgear originally and it died after a little over a year. I called them up to complain and they offered to replace if I shipped in the old one at my cost (which I did). The replacement unit died again a couple of weeks ago, after a little over a year of occasional use. Customer Rating: Summary: Short Life Comment: I have owned four of these. One for the motorcycle, one for the truck, and one each for the cars.
The Good:
These gauges are accurate, repeatable, and very small.
The Bad:
They are disposable. I get maybe a year out of them, which is perhaps 2 uses. I tried to replace the battery in one. It would be somewhat challenging for someone who did not have the necessary micro screw drivers and the patience to remove various items. Inside you will find a shoddy piece of electrical tape holding the battery in place - nice touch. After I installed a new battery, reassembled the gauge, and turned it on, I discovered that it reset itself to units that are unfamiliar to me, perhaps pascals. I never did figure out how to change the units. The price of the product is not worth the time I put into it anyway.
I don't recommend this digital pressure gauge. Customer Rating: Summary: best on the market Comment: This is the best one i have found on the market i have tried and tested plenty of random and unsavoury air pressure and tread depth tools and this is by far the best with is nice small design and digital read out amazing i am a very happy customer
