CPS VG200 Digital Vacuum Gauge | NIST Calibration for Accuracy | Withstand 400 Psi Pressure, Easy-to-Read 5-Digit LCD | Perfect for Vacuum Testing in HVAC/R Systems

Had one I used for about 5 years, never had a problem with it. It was hit many times with refrigerant and positive pressures and still worked. Then I decided to go with the Fieldpiece wireless gauge for some stupid reason. Within 4 months it got hit with very little of the same as above. tried several times to clean it to no avail. The readings are all over the place. That was a complete waste of $225.00! I sold my old CPS to one of my coworkers and it's still running like a champ! I bought this one from my past experience with it, and I will never look back again. It's bullet proof and there is none BETTER!

This CPS VG200 Digital Vacuum Gauge with NIST Calibration for accuracy is the GOLD STANDARD for this type of gauge, and so is naturally a bit pricey. There are others at lower cost available, that work fine enough for most situations, if all you need to pull is a 300 to 500 Micron vacuum. However, this vacuum gauge can withstand 400 PSI of positive pressure, and can be cleaned of oil with a shot of denatured alchohol, uses one 9-volt alkaline battery, and comes with a pass-through Y fitting to monitor vacuum at the hose connection, has a hanger, and well-built carrying case. So if you are a Pro or still learning the trade, this is an outstanding item to add to your tool collection.

I almost sent this guage back. I had it connected directly to my vacuum pump and each time I shut the pump off the pressure would drop immediately. I notice that one of the ports on my pump had a plastic cap. I was not confident this cap would seal perfectly. I then decided to isolate the gauge with a small ball valve. Success. The plastic cap was the problem. The guage is GOOD.

I really love the product. I’ll order again

Gauge seems to be accurate, included tee is JUNK!Gauge went to 3 microns…. Gauge with the included tee won’t go below 500 on a 9cfm pump. Tried a different seal in it with zero change. The solder / braze job on it is leaking. Not happy about that!

Muy fácil para entenderlo , trae su manual y muy buena su calidad ,batería de 9v incorporada

The media could not be loaded. Alot of good reviews led me to purchase this and Maybe I got a lemon. This isn't a cheap tool which is why I was expecting some degree of quality. 1st time using it and this thing went crazy compared to my fieldpiece microns. Took it off the system and it's reading microns at atmospheric pressure. I have really lost faith in the quality of all tools . This is just another example.

I received a used one which was covered in refrigerant oil and requested a replacement. I would have been ok with a used on but not at full price. A replacement was sent promptly and a precision micron gauge like this will make your mini split installs a lot easier and give you greater confidence that you have pulled a deep vacuum.
