The 5 Best shaft RPM gauges (2023 reviews)

The agptek shaft rpm gauge's material feels more premium than its price would suggest. This device measures the rpm of a physically rotating / spinning object and that can have the included reflective tape attached to it. It works well and is able to measure reliably over a good range of speeds. It comes with reflective tape that you put on whatever you want to check the speed on. It will work on any system that has a rotating component that is accessible to its laser beam and that can have the included reflective tape attached to it.

The reflective tape is easy to use. It has a wide range of applications including measuring rotating speed of a machine, motors, model cars, wheels, lathe for metal or wood cutting work etc. The laser is pointed at the reflective material and counts the revolutions of the rotating ( reflective part.

Best For hydro electric system: Cybertech shaft RPM GAUGE

Buy on Amazon

Cybertech line of gauge come in a pretty wide variety of styles, so you can definitely find one that suits your individual preferences and needs. This is all you need for most home or light duty industrial applications. It comes in an nice zipper case and a few strips of foil tape. The tachometer is easy to use and has held up to the rigors of being used by an entire high school baseball team all winter and spring. It includes plenty of reflective strips for lots of applications and the case is adequate to keep it all in.

The position of the buttons could be improved to allow viewing the screen more easily while shooting. The tachometer checks the rpm by sensing that reflection when it goes by.

Why We Like This:

Works well in shade, not in the light of the day
Spin rate for curveballs and fastballs

Best For wood lathe: Digiten shaft RPM GAUGE

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate gauge. The digiten shaft rpm gauge is exactly that - it's a simple gauge that hits all the right notes. This hall sensor acts as a NO switch. It improves lathe use and also provides 1 pulse / rev. The pitch is 1.0MM via a metric thread gauge. It claims to measure speeds up to 9, 999 rpm. The sensor is looking for the magnetic field moving past it to generate a signal to count. This tachometer will not work for more than one pulse per second input without having an external N. The instructions are simple because it's a simple devise. It gives good accurate reading. This sensor acts as a NO switch.

Why We Like This:

Installation was very direct and simple
New and hot release

Best With phone: Reed instruments shaft RPM GAUGE

Buy on Amazon

If you often find yourself scrambling for convenient and suitable gauge, reed instruments shaft rpm gauge should be your first option for buying. It features a built-in laser pointer to assist with identifying the target area. It measures surface speed from 0.5 to 1, 999.9m/min. It includes reflective tape, large and small cone tip adapters, funnel adapter, wheel adapter, batteries and hard carrying case. It is a laser beam that works at a distance from 50 to 500mm for user safety. It is a height, the vertical distance from the lowest to highest point.

It comes with a range of attachments that can be used to measure speed on different kinds of rotary systems, which may include tips used for measuring shafts with a central hole or flat end surfaces, and rotary wheels for measuring conveyor belts. It is autoranging, to display the most appropriate test result value automatically. It has a QC (quality control) sticker that actually means something. It is suitable for measuring rotational speed and other measurements in mechanical or industrial engineering environments.

Why We Like This:

Large lcd display and low battery indicator
Works very well in both contact and optical mode
Simple to use and worked great out of the box

Best With wheel attachment: Extech shaft RPM GAUGE

Buy on Amazon

If you often find yourself scrambling for appropriate and satisfactory gauge, extech shaft rpm gauge is your solution. A digital tachometer like Extech’s rpm33 allows you to measure the revolutions of motors and rotating shafts to ensure operating efficiency. It measures pulses and rpms. It is built with a quartz crystal oscillator so that readings maintain a high level of accuracy. The meter can measure the linear surface speed ( m / min ft / min), so you will need to follow the next procedure.

This rpm meter has a wheel attachment that directly measures surface speed in m / min or ft / min. It is easy to use tachometer fir measuring belt or roller speeds from a distance up to 1.6ft (0.5m), so you can safely collect the data you need. This digital tachometer also allows you to store and recall up to 10 data sets with 4 parameters (measurement, max, min and average) for convenient future reference.
