An hourglass functions similarly to a timer. It’s a tool to give you a certain interval time. However, unlike a digital timer that you are probably able to change the time interval, the time interval of hourglasses is fixed. In addition, although it’s said 10 minutes, for example, you should never expect it as accurate … Read more
A spectrum analyzer is a test instrument that functions to measure and visualize the signal amplitude over a certain frequency range. The screen visualizes them in a graphic of amplitude vs frequency. The signal amplitude is displayed on the Y-axis, while the frequency range is displayed on the X-axis. The signal amplitude is commonly expressed … Read more

Test indicator is a precision measuring tool in the workshop that you could use to measure runout, roundness, flatness, parallelism, and squareness. It’s a recommended choice rather than a plunger dial indicator when it comes to measuring in a higher degree of resolution. In addition to its functions, it can overcome the measuring challenge when … Read more
A dial indicator or dial gauge is able to magnify a tiny hard-to-observe length difference into a rotatable easy-to-count distance. When the plunger moves back and forth, it drives the needle/pointer on the dial scale to rotate. Nicely, this workshop precision measuring tool can give you a resolution down to .001″, even .0001″. By using … Read more
A tachometer is a measuring tool that functions to measure the RPM (revolution per minute) of a particular rotating object. For instance, if you are going to measure the RPM speed of a spindle motor of a milling machine, this device is able to do that. People use this device in many areas such as … Read more
The ruler is the most familiar linear measurement tool in our life. It’s easy to find and generally affordable. People use a ruler to draw a line with a certain defined length. In addition, it functions to measure a linear distance between two spots. Commonly, a ruler comes in imperial (inch) and metric (cm) reading. … Read more
