Get rid of those probes, just kidding, all though, they’re nice for data logging and or a snap shot of the system while on site. I personally dumped the probes years ago and went back to my (22 year old) Y.J. manifold or just a single analog gauge with a tee on it and cooper temp probes for larger tonnage equipment and the thermistor style pipe clap for 20 ton or below.
