Good day, I wanted to ask a question about the IMG-100 NW25 high vacuum sensor.

The IMG100 gauge has a sensitivity of 2.7 A/Torr +/- 20% at 5 x 10-6 Torr. It is accurate +/- 50 % within a pressure decade. This is normal for them not to have the exact same pressure reading, but they should all be the same range (Ex: 10-6torr, 10-9torr, etc.) 

There is no way to check the gauge with a resistance check.

100% IPA or acetone are recommended for most UHV cleaning applications.

Thanks for the answers to the previous questions!
I would also like to know what analog can replace the sensor IMG-100?
And regarding the previous questions (2) I did not express myself correctly, now not on the sensor itself, but on the cable connect a resistance and look at the pressure through a vacuum gauge?

Any of the Agilent the FRG gauges can replaced the IMG, but an analog board would be needed in the XGS controller. There is no easy way to directly measure the output signal of the IMG gauge on the sensor head or from the gauge cable.
