FieldpieceMG44 - Wireless Vacuum Gauge

I own a CPS VG200 vacuum gauge and it seems that the sensor needs to be cleaned with denatured alcohol after every use and I have grown to distrust its reliabilty. So I ordered the Fieldpiece vacuum gauge and I have used it twice thus far to pull a vacuum on 2 recovery cylinders.1. The field piece appears to be accurate.2. There is no leak or crazy changes during the evacuation process.3. The decay test was excellent.4. The wireless feature is very helpful. You can set the auto turn-off feature for 1 hour or less, or just disable it and keep monitoring the progress of the micrin gauge from indoors. Two AA batteries came with it.5. The wireless feature DOES NOT work within the 1000 feet range. It may work if there are no walls. It worked for me at about 30 feet distance from my garage to the farthest point inside my house, but stopped picking up the signal when I went to the backyard.6. By comparison to the CPS micron gauge, I think the Fieldpiece is by far more reliable. I changed the gasket on the CPS vacuum gauge and when it reaches 150 microns the reading starts rising again beyond 500 microns on its own, and even went beyond 1500 microns. I cleaned the CPS VG 200 sensor per manufacturer's instructions and changed the gasket, but it still was irratic. I switched to the Fieldpiece right way and the problem did not reoccur.7. I do not find it necessary to spend more money on another brand or gauge, just because the other brand has more bells and whistles. Invest in other tools you need.I have used an Appion valve during the process, a Robinair 4 cfm vacuum pump with aa ballaster and an isolation valve, and two 3/8 hoses. The hoses were connected to a Yellow Jacket vacuum manifold.Take the time to play with the menu and insert the batteries with the positive polarity facing up towards the back cover.As I prime member I received the gauge on a Sunday, which I ordered on a Friday evening. The Amazon driver did an excellent job in terms of texting and the safe delivery of the product. These people need to be appreciated for their effort in keeping us customers happy when they deliver our goodies.Reviewed on 07/05/2024

Works excellent. Like the display on the piece itself. It does not register at 1000 feet away. I really didn’t expect it to.

Worked great for evacuation of a mini-split system.

This thing just makes my work that much more professional

I’m in HVAC installer and I use a lot of fieldpiece equipment. I love that this one can connect with the fieldpiece app along with my spark pros. Makes my install very easy and I’m able to save the process.

We ordered this tool and received a used one.

They do NOT work as far away as the other probes, you need to turn on this gauge and try to link up to your device very quickly or it won't link, appears to be accurate, works well with 1 hose setup

An extremely accurate Micron gauge connects right to the app on your phone.
