All the products we mentioned above are great. Yes, it is important to know of a few factors that you need to consider before investing in a micron gauge.
Here they are:
The accuracy of a micron gauge is the main indicator of its quality and performance. Unfortunately, there is no way to clearly determine the accuracy and precision of a micron gauge. The best way to be sure is to buy a gauge that comes with NIST certifications. The certification is only granted after the device follows a set of standards. Hence, it can be a way to ensure quality.
What good is a device if it does not have convenient design and durable construction? If you want to use your micron gauge in the garage or for rough and tough work, it is necessary that you go for something that is durable and sturdy.
Most of the micron gauges from good brands come with rugged construction however, not every micron gauge features water and dust proofing. Thus, based on your needs, choose your micron gauge wisely.
Design-wise, usually, micron gauges don't cause any issues. They come in varied sizes, hence, if you want something portable and easy to carry, opt for a small one.
No matter which model and brand you buy, dirt is a micro gauge's worst enemy. It can not only mess with the performance of the device but can also reduce the device's precision and accuracy.
Every micron gauge has its own set of instructions to follow when it comes to maintenance. You don't want a device that requires 20 to 30 minutes of cleaning after every operation. Going for a device that is easy to maintain and clean will make things more convenient.
Micron Gauges come with two types of displays namely analog displays and digital displays. Analog displays are pretty outdated and in comparison, to them, digital displays have bigger fonts and are easier to read. They also allow users to switch between different units easily.
Smart micron gauges appear to be taking over the market. These gauges can connect to smartphones via the brand-specific application and allow users to save and view all the previous data caught using the gauge.
Smartphone communication and connectivity opens doors to a number of features that traditional micron gauges cannot perform.
To connect a micron gauge to a certain device, whether using wires or Bluetooth, you have to check its device compatibility. Every device has a certain connection size, hence, before buying a micron gauge, make sure it is compatible with the machine(s) you want to use it with.
A micron gauge is a pretty nifty tool that helps can help facilitate the longevity of your machines. It allows the user to promptly find the changes in pressure reading. Despite being super useful, a micron gauge, when not used properly gives distorted results.
It works by removing non-condensable medium like air moisture to complete the process of evacuation. Here's a step by step guide of using a micron gauge:
It is a good practice to keep your pump, valves, and hoses clean since they can accumulate moisture over time.
A micron gauge can help add years to your machines. We have listed down the 9 best micron gauges on the market. Each one is selected based on a certain criterion and a range of budget. Cheaper alternatives might be tempting but they are neither accurate nor long-lasting.
Moreover, almost all the micron gauges mentioned in the article have a set of replacement parts easily available, hence, even if you have to get something replaced, you will not have to go through the hassle of replacing the whole system.
