🌡️ Yellow Jacket 69044 Vacuum Gauge: Accurate Measurement from 0-30" Hg/760-0 Torr, 3 1/8" Diameter Review

Absolute rubbish! During the first use, when I was close to full vacuum, the sensor broke and went back to zero where it stopped moving. Save money, buy digital.

Very good quality as I have come to expect from the Yellow Jacket, shows the full range to the limit of what my vacuum pump is capable of. My guess is that those who say the gauge doesn't show up in the high vacuum range have vacuum leaks in their system.

Does not indicate high vacuum above 50 Torr. Either I have a broken device or according to other comments it is not able to read the full vacuum. The pump used for testing is greater than 0.010mmHg. (10 microns).

Large, accurate (as far as I can measure) vacuum gauge. The device I received has a calibration adjustment screw. My problem is that the needle gets stuck and can be deflected more than 0.5 inch. Each time I press the sensor, the needle moves +/- about 0.25 inches.

I've searched everywhere for an inexpensive vacuum gauge with a measuring range of 0-760 mmHg. Laboratory companies sell them for hundreds of dollars. I got it in a few days and hooked it up directly to a 3/8" vacuum hose with a zip tie and it worked great. Note. Some other reviews incorrectly state that the fitting is a 1/4" " NPT thread. The product description is correct, it is 1/8" NPT. This is an unusual size that you are unlikely to find in a hardware store so you will likely need to…

Yellow Case 69044 Vacuum Gauge The Hg (inches of mercury) scale on this gauge ranges from 0 inHg (atmospheric pressure) to approximately 30 inHg. That's 30 inches of mercury. Note that 29.92 inches of mercury is an ideal vacuum, but this is unattainable on Earth. ) says the only way to accurately measure vacuum is to use a digital pressure gauge like the SuperEvac Yellow Jacket 69075 full-range LCD vacuum gauge in a case, but that's probably overkill for the DIYer. I used this gauge when…

This large sensor appears to be of very high quality and I'm totally satisfied *(I've changed my mind on this comment, see update below). The polycarbonate lens is thick and the stylus is vibration-dampened so it feels smooth and clear even when mounted close to the engine. I used to try to be a cheapskate and bought the Winters PEM series (http://www.amazon.com). .com/Winters-Economy-Pressure-Display-Accuracy/dp/B0087UBCIE) which came straight out with a non-working reading of about -20psi…
