Accutire MS-4021B Digital Tire Pressure Gauge with 4 Valve Caps, 5-150psi (psi, bar, kPa, kg/cm2)

Easy to use and easy to read the display.

Very good tire gauge. Does exactly what it says and easy to use. Great gift for grandson heading off to college.

Tire pressure gauges can run from the simple pencil types to the more sophisticated versions with dial or digital displays. Picking a good one depends on your personal needs, more than anything. Bought this Accutire MS-4021B Digital Tire Pressure Gauge when it was on a Lightning Deal and based on personal experience with an older model from the same company. My needs were specific: measuring the tire pressure on a mountain bike. This review wouldn't even be here had I not lost the original gauge by leaving it in my back pocket when going out on a quick ride that became extended. ◆ Likes: + Clear LCD display; easy to read in varying conditions + Good tire pressure range; from 5-150psi in ½-pound increments + Well designed; angled head makes it easy to use + Uses three LR44/A76 batteries; readily available ◆ Dislikes: - The three LR44/A76 button cell batteries are tricky to replace ◆ In Use: This digital tire pressure gauge is quite straightforward, and the directions for use and warranty info are printed on the back of the package. Before using it for the first time, it's necessary to pull out the small white paper tab from the rear of the handle and it will work just fine. To use the gauge, simply push the nozzle onto the tire valve stem and press down smoothly so that you don't hear air hissing, then hold it there until you see the pressure reading lock in on the digital display. The directions also include directions for checking the "zero setting," so be sure to remove the cardboard portion and keep it for future reference. My MTB tires are 26 x 1.95-inch, and on the sidewall the pressure range is noted as 30-65psi. I changed the air pressure a few times to see how well the gauge would respond, and it worked properly. I then checked it against my Planet Bike Analog Bicycle Dial Tire Gauge , which is very accurate and rated at 0-140psi, and the one that is used in the field. The two were very close, though the Accutire MS-4021B is a bit handier to use at a glance due to its digital readout. My only issue with this Accutire gauge is that the three button cell batteries are tricky to remove and replace. You'll need a small Philips jewelers screwdriver to remove the battery cover on the black handle, and you'll need to use care in prying out the small batteries or they will go flying... as happened to me the first time. When I reinserted the batteries, I cut a small, very thin piece of plastic and slipped it underneath the batteries so that they could be removed easier the next time. A small piece of tape would do just as well, but it a small nuisance. ◆ Summary: The Accutire MS-4021B Digital Tire Pressure Gauge is a decent product, and one that is easy to use. Bottom line is that it's a good multipurpose digital tire pressure gauge. 7/30/2013

Works well. Very accurate.

Works well

Love it no guessing trying to understand the reading of PSI. The original tire pressure gauges from years ago are hard to read. My first digital and Love this one PERIOD.

Works great. Haven't compared indicated tire pressures with a few of my other tire pressure gauges, but it is easy to use, lightweight and compact.

Reasonably priced digital tire gauge. It replaced an older dial gauge I had for decades and stopped giving reliable results. I take my 4X4 on the beach and have to air down to drive on the sand. I take it down to 18 psi and then using the air pumps at the park, pump back to 36 psi. So, I need a reliable gauge, and this one fits the bill. My only issue was the piece of plastic tape that keeps the batteries (included with the unit) from connecting to the unit would not pull out easy and I had to use a small Philips screwdriver to loosen the battery compartment and remove the plastic piece. Other than that, works fine

El general facil de usar solo es preionar un boton y el chequeo. Llevo unos meses con el la pila sigue igual funcionando y se ve de buen calidad a precio accesible.

This gauge is durable, easy to use, and easy to keep handy in a glovebox or door pocket. Reads accurately when tested against a calibrated air gauge. Still running on the original battery after 3+ years of monthly use.

This fortunately reads psi. It reads the same as another gauge I have and agrees with the car's TPMS so all three must be correct. I have an old version of this gauge from probably 20 years ago and it still works on the original battery. It's very easy to use and is highly recommended.

Accurate as expected

Excelente producto. Se ve claro, es preciso. Solamente a veces la valvulares negra como que si se afloja y se debe de apretar antes de medir. Para que la medición sea correcta se debe de medir en frio. Entonces carga las llantas a 6 psi más de lo que indica el manual. De ahí ya lo dejas la noche y en la mañana antes de partir lo dejas. Manejar con las llantas bajas causa el mayor desgaste y que exploten en carretera.
