Review on 🔧 Enhance Accuracy with Yellow Jacket 40332 Blue Compound Gauge and 19110 Quick Coupler by Paul Rosemark

This gauge arrived today. Not _quite_ as shown in the description. The gap between the blue and green scales is below zero PSIG, and this is as close to 0 as the gauge can be calibrated. To determine the superheat value, this difference is enough to make it almost useless. It's a great gauge and the short sleeve is incredibly handy for checking the pressure on an air conditioner with a critical load, as close to leaking refrigerant as it gets. But the sensor error is simply unacceptable. Sorry, but I'll get back to you now. I'll get another gauge as a spare and I'll order the clutch separately. I hope it resets properly.
