When your vacuum line uses a Convectron-style pressure sensor, the exact model matters more than the brand sticker. If you are trying to keep a semiconductor or PCB wafer-processing system running without replacing the whole control loop, a replacement gauge like the Granville-Phillips Convectron Gauge 275071 can be the quicker route.
Quick verdict
This is a used Granville-Phillips Convectron Gauge 275071, offered at $85.00 for semiconductor and PCB manufacturing work. The condition is plainly stated as used, and the model number gives you a specific reference point. If you already have a compatible controller and need a gauge, this is worth evaluating. If you require a new unit or full calibration documentation, it is not that.
Who it suits
The Granville-Phillips Convectron Gauge 275071 suits buyers comfortable with equipment that has been in service and who value a concrete model number for replacement planning. It also fits anyone looking for a gauge for wafer-processing lines where the existing system already supports this model.
What stands out from the listed details
The product title identifies it as a Granville-Phillips Convectron Gauge, model 275071. The listed description states it is designed for accurate measurements and precision in wafer processing. That combination makes it a concrete candidate for a replacement, provided you can confirm compatibility. The condition is explicitly stated, which at least sets expectations before you consider the part.
Meaningful trade-offs
The biggest trade-off is that this is a gauge that has already been in service. The practical implication is that you will want to use your normal process for qualifying a used vacuum instrument. Calibration status, fit to your controller, and connection compatibility are all things to confirm before purchase. The model number should help you pull up the needed specifications from your own records or from Granville-Phillips documentation.
Bottom line
For a buyer who already knows the Granville-Phillips Convectron Gauge 275071 and how it fits into their semiconductor or PCB manufacturing vacuum system, the condition is the main factor to weigh. The model number and the stated accuracy for wafer processing give you enough to start a compatibility check before deciding.
Granville-Phillips Convectron Gauge 275071
The listed unit is a Granville-Phillips Convectron Gauge, model 275071, priced at $85.00. It is described as accurate and precise for wafer processing, which gives you a reason to consider it if you need a replacement for a similar unit. The limitation is that it is explicitly used, and you will need to confirm calibration, certification, and connection details through your own process before it can fit into a validated environment.
