ARB is an Australian 4×4 equipment maker, well known among off-road drivers for recovery gear, air compressors and the small tools that make trail days easier. Its tire pressure gauges are built for the same people: drivers who let air out of their tires before sand, rock or mud and pump it back up before returning to the road. If you are new to four-wheel driving, or buying a gift for someone who is, this guide explains the words on the box in simple terms.
The four ARB gauges here differ in two ways: whether they read out on a digital screen or an analogue needle dial, and whether they only measure, also let air out quickly as a deflator, or connect to a compressor to inflate as well.
ARB Tire Pressure Gauges Compared
| Gauge | Display | What it does | Scales | Listed size and weight |
|---|---|---|---|---|
| ARB510 E-Z Digital Tire Deflator | Digital, blue backlit LCD | Measures and deflates | PSI, bar, kPa, kgf | 7.5 x 6.5 x 1.5 in, 350 g |
| ARB601A Digital Tire Pressure Gauge | Digital, blue backlit LCD | Measures, inflates and deflates | PSI, bar, kPa | 7.87 x 2.95 x 3.54 in, weight not listed |
| ARB605B Analogue Tire Inflator | Analogue, oil-filled dial | Measures, inflates, bleeds air | PSI | 11 x 5 x 4 in, 3 lb |
| ARB506A Analogue Pressure Gauge | Analogue dial | Measures, with reset button | PSI and bar | 14.17 x 3.15 x 1.57 in, 16 oz |
A few terms first. Airing down means lowering tire pressure before off-road driving; a softer tire spreads out, grips better on loose surfaces and rides more comfortably over rocks. A deflator is a tool that lets air out quickly and in a controlled way, so you are not kneeling by each wheel pressing a valve for minutes. An inflator connects to an air compressor so you can fill the tire while watching the gauge. A chuck is the fitting that attaches to the tire valve; screw-on chucks lock in place, while push-on chucks are quicker to attach. We compared ARB’s listings and specifications, not our own measurements.

ARB510 ARB E-Z Digital Tire Deflator
Best for: Fast airing down before the trail
Pros
- Rapid air-down deflator
- Backlit LCD, four units
- Accuracy of 1 psi at 15-75 psi
Cons
- No inflation function listed
The ARB510 ARB E-Z Digital Tire Deflator is built for one job done well: letting air out quickly while showing you exactly where the pressure is. It combines a rapid air-down deflator with a digital gauge, and a screw-on chuck that suits all Schrader valves, the standard valve on car and truck tires, for a secure connection while air rushes out.
The large LCD has a blue backlight, which helps at dawn or dusk, and it reads in four units: 0 to 200 psi, 0 to 14 bar, 0 to 1,400 kPa and 0 to 14 kgf. The listing gives accuracy as plus or minus 1 psi between 15 and 75 psi, which covers typical road and off-road pressures. It switches on and off automatically, has a 250mm braided line, brass components and crimps, a rubber bump guard against drops and an updated, larger carry pouch. The listed size is 7.5 x 6.5 x 1.5 inches and the weight 350 g.
This suits the driver who airs down at the start of every trail and wants it done fast. It does not list an inflation feature, so you will need a separate way to pump back up; the ARB601A covers both jobs.

ARB ARB601A Digital Tire Pressure Gauge
Best for: Owners with an onboard compressor
Pros
- Inflates and deflates
- Push-on high-flow chuck
- Up to 200 hours battery runtime
Cons
- Needs batteries
- Needs an air source to inflate
The ARB ARB601A Digital Tire Pressure Gauge is the all-in-one digital option. The listing calls it a digital tire inflator and deflator: you connect it to an air source to fill tires while reading the pressure, and use it to let air out when airing down. It uses a large blue backlit LCD and reads 0 to 200 psi, 0 to 14 bar and 0 to 1,400 kPa.
ARB highlights an updated inflation chuck with a push-on connection designed for minimal air loss, nickel-plated brass to resist corrosion, braided stainless steel hose reinforcement and a high-flow design for quicker filling. The listing also names up to 200 hours of runtime on a set of batteries, a battery indicator, a coated thumb trigger, a rubber bump guard and a 23.5-inch dual swivel coated hose. It comes with a 1-year manufacturer warranty, uses NPT threads and measures 7.87 x 2.95 x 3.54 inches. The weight is not listed.
This is the pick for someone who already carries a compressor, or plans to, and wants one tool for the whole cycle of airing down and back up. If you prefer not to rely on batteries, the analogue ARB605B does a similar job with a needle dial.
ARB ARB605B Analogue Tire Inflator PSI for a Classic Dial

ARB ARB605B Analogue Tire Inflator PSI
Best for: Drivers who prefer a needle dial
Pros
- Oil-filled larger dial
- Solid brass geared movement
- Air bleed button
Cons
- Listing text mixes in digital wording
- Heaviest at 3 pounds
The ARB ARB605B Analogue Tire Inflator PSI is the analogue take on the inflator. It uses an updated gauge with a larger dial for easier reading and oil-filled construction. The oil inside cushions the needle and internal parts from vibration, which is useful in a bouncing 4×4. The movement is fully geared solid brass with a bronze Bourdon tube, a classic mechanical design where a curved tube straightens slightly under pressure and moves the needle.
It has a protective rubber gauge guard and an air bleed button for letting air out. It also has an updated inflation chuck, and it reads in PSI. The listed size is 11 x 5 x 4 inches, the weight 3 pounds, and it carries a 1-year manufacturer warranty. One caution: the description repeats text about a digital blue backlit display that belongs to ARB’s digital inflator, while the title, specifications and features all say this is an analogue unit. We treat it as analogue, which is what the part name indicates.
This suits drivers who like a needle they can read at a glance and prefer no batteries. If you want the fastest possible air-down, the dedicated ARB510 deflator is quicker to use.
ARB ARB506A Updated Analogue Design Air Pressure Gauge for Simple Checks

ARB ARB506A Updated Analogue Design Air
Best for: Simple checking and a glovebox gift
Pros
- No batteries needed
- Dual PSI and bar scales
- Dual chuck for all valve types
Cons
- Measures only, no deflator listed
- Dial size wording conflicts
The ARB ARB506A Updated Analogue Design Air pressure gauge is the simplest tool here. It measures tire pressure on easy-to-read dual scales in PSI and bar, with a flexible hose and a dual chuck designed for all rim and valve types. A gauge reset button returns the needle to zero after a reading, and a rubber guard protects the dial.
The listing describes the updated analogue design with a larger dial and oil-filled construction, but also lists “small dial” among the features, so the exact dial size is unclear. It measures 14.17 x 3.15 x 1.57 inches, weighs 16 ounces and has a 1-year manufacturer warranty. It does not list a deflator or inflator function.
This makes a practical glovebox tool or a small gift for a new 4×4 owner. For regular airing down, pair it with a deflator or choose the ARB510. For everyday cars, our guide to a compact digital tire gauge covers smaller, simpler options.
How to Choose the Right ARB Tire Pressure Gauge
Digital or analogue. Digital gauges (ARB510, ARB601A) show exact numbers on a backlit screen and offer several units, but need batteries. Analogue gauges (ARB605B, ARB506A) need no batteries and use oil-filled dials to handle vibration.
Do you air down often. If yes, a deflator saves a lot of time. The ARB510 is built for rapid air-down, and the ARB601A and ARB605B let you bleed air too.
Do you carry a compressor. The ARB601A and ARB605B are inflators that connect to an air source. The ARB510 and ARB506A do not list this.
Units you need. The ARB510 reads psi, bar, kPa and kgf; the ARB601A reads psi, bar and kPa; the ARB506A reads psi and bar; the ARB605B reads psi.
