Description of Enhanced Precision with Supco VG64 Digital Connection

Vacuum gauge with ultra-fine resolution (0.5 to 1000 micron), and a 0-12,000 micron vacuum range for accurate pressure measurement during system evacuation, and high-precision laboratory tests. Programmable, audible and visual alarm for high and low vacuum indicates when threshold is reached. Backlit, LCD digital display of seven international units including microns, Pascal, and PSI, and a 1/2-second response time. Auto shut-off eight hours after alarm activation, and when alarm is disabled. Built-in hanging apparatus for maneuverability.

Don't hold vacuum - update

I finally managed to use it and it reads a vacuum under 500 microns pretty well but it won't hold vacuum. It started to rise as soon as I closed the valve. Tried my friend's vacuum gauge with the same hoses and pump assembly and it held a vacuum. I tried again with my Supco gauge and it didn't hold a vacuum. I am using it for the first time and it is NOT good. Update I should have written a review for this product a while ago. The company replaced my vacuum gauge right away with no problems and

Pros
  • Built in gimbal for maneuverability
Cons
  • I'll add later

Internal leaks make it worse than useless. Internal leaks force you to look for non-existent system leaks.

When we first used this we drew a vacuum to 410 microns, isolated the pump, and then turned the pump off. The vacuum slowly increased to 1200-1300 microns. Assuming we had a leak, we pressurized the system and checked all connections for leaks. The pressure seemed to stay at 250psi. No leaks were found so we repeated the evacuation with new o-rings in the hoses and a different pump isolation valve with the same results. We figured we had a very small leak that we just couldn't find. I…

Pros
  • Automatically shuts off eight hours after the alarm goes off and when the alarm goes off
Cons
  • Slightly torn

Bad reputation with junk

Did I believe the bad reviews when I bought this sensor ? Not really. I usually attribute bad reviews to a combination of user error, unrealistic expectations, a poor quality product, or all of the above. Do I believe these bad reviews now? Oh yeah. I can't say for sure if the device I received was returned, but the film covering the display looked like it had been taken off and put back on, otherwise the sensor looked like new. To test it out before installing it in an HVAC system, I hooked it

Pros
  • Backlit digital LCD display showing seven international units including microns, pascals and PSI and a 1/2 second response time
Cons
  • Not sure
