CPS® VG200 Vacrometer® Digital Micron Vacuum Gauge Digital vacuum gauge with 5 digit LCD display reads Microns, Torr, In/Hg or mBar. Calibrated to strict NIST standards for accuracy and reliability Monitors evacuation procedures from start to finish. Because of strict NIST standards and continuous calibration testing, the VG200 earned a reputation of best-in-class for its accuracy and reliability. A simple 2 button operation gives the flexibility to select or change units: MICRONS, MILLIBAR, TORR and INCHES/HG quickly during any procedure. It will also automatically compensate for varying temperature conditions, with no manual adjustments necessary. VG200 includes: Gauge Hook, Adapter “T-fitting” and Padded Vinyl Case.
