Review on 🔬 CPS Products Portable Digital Atmospheric Monitor by Carlos Long

Bought from another site but share my experience with other users. Installed my first minisplit with it. I tightened the fittings with pliers, concerned that there would be a vacuum leak around the pan head. After tightening all the hardware, I found that it held a great vacuum. It turns off automatically after 5-10 minutes to save battery, but I'd prefer to keep it on longer as I spent hours resetting it to the server time and waiting to check for leaks. However, the setup worked well and I felt confident as I drained the refrigerant into the lines.
