Digital Gauge Manifold Buying Guide

Now as I am done with the reviews, I would like to share a few points that you should keep in mind before buying a digital manifold gauge.

Certain factors are the bare minimum when it comes to owning a manifold. You should not compromise on these points as they are the ones at least every potential manifold you are considering, should have.

Body

Preferably, a manifold gauge should have a brass or metal body (mainly Aluminum). These are the most durable ones. Since a gauge is a long-term investment, you don't want to compromise on the quality of your work, for just a few dollars.

Compatibility

In the market, eventually, the competition comes down to the number of refrigerant systems a manifold gauge is calibrated with. I may not be able to tell the ideal number as all manifolds differ in price and features.

However, do check whether it's calibrated with the industry's standards.

Additional HVAC functions

Some models of digital gauge manifold are also equipped with thermistors which, when connected properly, perform automatic calculation of superheating and sub-cooling.  If you perform these readings on a frequent basis then be sure to select a gauge manifold which is capable.

Suspension hook

This may seem trivial, but it is as important. A suspension hook eases the job at the workplace. So, don't go for manifolds without one.  Also, check for the quality of the hook as well. This will make HVAC service much easier when in the field.

Hose size

The recommended size for a hose is 60". Slight deviation for this can be accommodated. If you can not go for this size, go for the nearest option.

Sight glass

This one is not a must-have but is a plus point.  Having a sight glass on your manifold can add to ease of refrigerant charging and recovery.

Conclusion

Now, as we conclude our list of top 10 best digital gauge manifolds, I hope you are now well prepared to buy one. In the buying guide, I tried to include all the necessary points you should keep in mind.

In the list, I added a few potential best digital manifolds so that you only select from the best. By choosing any of the manifolds listed above, you’ll be going with a quality product made by quality manufacturers.
